Amphetamine (USAN, abbreviated from alpha-methylphenethylamine) or amfetamine (INN) is a psychostimulant drug of the phenethylamine class that produces increased wakefulness and focus in association with decreased fatigue and appetite.

Brand names of medications that contain, or metabolize into, amphetamine include Adderall, Dexedrine, Dextrostat, Desoxyn,[3] ProCentra, and Vyvanse, as well as Benzedrine in the past.

The drug is also used recreationally and as a performance enhancer. Recreational users of amphetamine have coined numerous street names for amphetamine, such as "speed". The European Monitoring Centre for Drugs and Drug Addiction reports the typical retail price of diluted amphetamine in Europe varied between €3 and €15 ($4 and $21.55 USD) a gram in half of the reporting countries. Racemic amphetamine on the street is typically about 10% pure.[4]

Effects

Data from The Lancet suggests amphetamine is ranked the 8th most addictive and 6th most harmful of 20 popular recreational drugs.[5]

Physical effects

Physical effects of amphetamine can include hyperactivity, dilated pupils, vasoconstriction, blood shot eyes, flushing, restlessness, dry mouth, bruxism, headache, tachycardia, bradycardia, tachypnea, hypertension, hypotension, fever, diaphoresis, diarrhea, constipation, blurred vision, aphasia, dizziness, twitching, insomnia, numbness, palpitations, arrhythmias, tremors, dry and/or itchy skin, acne, pallor, convulsions, and with chronic and/or high doses, seizure, stroke, coma, heart attack and death can occur.[6][7][8][9][10] There is also significant[weasel words] research that highlights the changes amphetamine produces in the dopaminergic system, even in clinical doses.[citation needed] One possible interpretation is that neurotoxic effects exist even with doses approved for medical use.[11]

Psychological effects

Psychological effects can include euphoria, anxiety, increased libido, alertness, concentration, energy, self-esteem, self-confidence, sociability, irritability, aggression, psychosomatic disorders, psychomotor agitation, grandiosity, repetitive and obsessive behaviors, paranoia, and with chronic and/or high doses, amphetamine psychosis can occur.[12][13]

Withdrawal effects

Withdrawal symptoms of amphetamine consist primarily of mental fatigue, mental depression and increased appetite. Symptoms may last for days with occasional use and weeks or months with chronic use, with severity dependent on the length of time and the amount of amphetamine used. Withdrawal symptoms may also include anxiety, agitation, excessive sleep, vivid or lucid dreams, deep REM sleep and suicidal ideation.[14][15][16]

Side effects

Contraindications

Amphetamine elevates cardiac output and blood pressure making it dangerous for use by patients with a history of heart disease or hypertension. Amphetamine can cause a life-threatening complication in patients taking MAOI antidepressants. The use of amphetamine and amphetamine-like drugs is contraindicated in patients with narrow-angle glaucoma or anatomically narrow angles. Like other sympathomimetic amines, amphetamine can induce transient mydriasis. In patients with narrow angles, pupillary dilation can provoke an acute attack of angle-closure glaucoma. These agents should also be avoided in patients with other forms of glaucoma, as mydriasis may occasionally increase intraocular pressure.[17]

Amphetamine has been shown to pass through into breast milk. Because of this, mothers taking amphetamine are advised to avoid breastfeeding during their course of treatment.[18]

Dependence and addiction

Main article: Amphetamine dependence

Tolerance is developed rapidly in amphetamine abuse; therefore, periods of extended use require increasing amounts of the drug in order to achieve the same effect.[19]

Overdose

An amphetamine overdose is rarely fatal [citation needed] but can lead to a number of different symptoms, including psychosis, chest pain, and hypertension.

Psychosis

Main article: Stimulant psychosis

Abuse of amphetamines can result in a stimulant psychosis that can present as a number of psychotic disorders (e.g. paranoia, hallucinations, delusions). The intensity and duration of symptoms may vary, but unlike true psychotic disorders (e.g., schizophrenia), stimulant psychoses are not considered to be permanent and will eventually resolve upon discontinuation of the drug's use.[citation needed]

Mechanism of action

Primary sites of action

File:Amphetamine2.png
Ball-and-stick model of amphetamine

Amphetamine exerts its behavioral effects by modulating several key neurotransmitters in the brain, including dopamine, serotonin, and norepinephrine. However, the activity of amphetamine throughout the brain appears to be specific;[20] certain receptors that respond to amphetamine in some regions of the brain tend not to do so in other regions. For instance, dopamine D2 receptors in the hippocampus, a region of the brain associated with forming new memories, appear to be unaffected by the presence of amphetamine.[20]

The major neural systems affected by amphetamine are largely implicated in the brain’s reward circuitry. Moreover, neurotransmitters involved in various reward pathways of the brain appear to be the primary targets of amphetamine.[21] One such neurotransmitter is dopamine, a chemical messenger heavily active in the mesolimbic and mesocortical reward pathways. Therefore, the anatomical components of these pathways — including the striatum, the nucleus accumbens, and the ventral striatum — have been found to be primary sites of amphetamine action.[22][23]

The fact that amphetamine influences neurotransmitter activity specifically in regions implicated in reward provides insight into the behavioral consequences of the drug, such as the stereotyped onset of euphoria.[23] A better understanding of the specific mechanisms by which amphetamine operates may increase our ability to treat amphetamine addiction, as the brain’s reward circuitry has been widely implicated in addictions of many types.[24]

Endogenous amphetamines

Amphetamine has been found to have several endogenous analogues; that is, molecules of a similar structure found naturally in the brain.[25] l-Phenylalanine and β-Phenethylamine are two examples, which are formed in the peripheral nervous system as well as in the brain itself. These molecules are thought to modulate levels of excitement and alertness, among other related affective states.

Dopamine

The most widely studied neurotransmitter with regard to amphetamine action in the central nervous system is dopamine. All of the addictive drugs appear to enhance dopamine neurotransmission, including amphetamine and methamphetamine.[26] Studies have shown that, in select regions, amphetamine increases the concentrations of dopamine in the synaptic cleft, thereby heightening the response of the post-synaptic neuron.[27] This specific action hints at the hedonic response to the drug as well as to the drug’s addictive quality.

The specific mechanisms by which amphetamine affects dopamine concentrations have been studied extensively. Currently, two major hypotheses have been proposed, which are not mutually exclusive. One theory emphasizes amphetamine’s actions on the vesicular level, increasing concentrations of dopamine in the cytosol of the pre-synaptic neuron.[25][28] The other focuses on the role of the dopamine transporter DAT, and proposes that amphetamine may interact with DAT to induce reverse transport of dopamine from the presynaptic neuron into the synaptic cleft.[21][29][30][31]

The former hypothesis is backed by studies from David Sulzer's lab at Columbia University demonstrating that injections of amphetamine result in rapid increases of cytosolic dopamine concentrations, while the drug decreases the number of dopamine molecules inside the synaptic vesicle.[32][33] Amphetamine is a substrate for a specific neuronal synaptic vesicle uptake transporter called VMAT2. When amphetamine is taken up by VMAT2, the vesicle releases dopamine molecules into the cytosol in exchange. The redistributed dopamine is then believed to interact with DAT to promote reverse transport.[25] Amphetamine and amphetamine derivatives are also weak bases that accept protons, and can collapse acidic pH gradients in the vesicles that would otherwise provide free energy for neurotransmitter accumulation: the "weak base hypothesis" of amphetamine action suggests that collapse of this free energy contributes to redistribution of dopamine from very high (molar) concentrations in the vesicles to the cytosol.[26][34] Calcium may be a key molecule involved in the interactions between amphetamine and VMATs.[28]

The increase of cytosolic dopamine appears to trigger neurotoxicity, as dopamine readily auto-oxidizes, so that amphetamine or methamphetamine's increase in cytosolic dopamine can lead to oxidative stress in the cytosol that in turn promotes autophagy-related degradation of dopamine axons and dendrites.[35]

The second hypothesis of amphetamine action on the plasma membrane dopamine transporter postulates a direct interaction between amphetamine and the DAT. The activity of DAT is believed to depend on specific phosphorylating kinases, such as protein kinase c, to be specific PKC-β.[31] Upon phosphorylation, DAT undergoes a conformational change that results in the transportation of DAT-bound dopamine from the extracellular to the intracellular environment.[30] In the presence of amphetamine, however, DAT has been observed to function in reverse, spitting dopamine out of the presynaptic neuron and into the synaptic cleft.[29] Thus, beyond inhibiting reuptake of dopamine, amphetamine also stimulates the release of dopamine molecules into the synapse.[21]

In support of the above hypothesis, it has been found that PKC-β inhibitors eliminate the effects of amphetamine on extracellular dopamine concentrations in the striatum of rats.[31] This data suggests that the PKC-β kinase may represent a key point of interaction between amphetamine and the DAT transporter.

Additional actions of amphetamine contribute to its ability to release dopamine from neurons, including action as an inhibitor of monoamine oxidase, an enzyme responsible for dopamine breakdown in the cytosol; an ability to enhance dopamine synthesis it is presumed via actions on the enzyme tyrosine hydroxylase, which synthesizes the dopamine precursor L-DOPA; and some blockade of the DAT, an action that amphetamine shares with cocaine.[36] Due to the combination of these actions and its long half-life, amphetamine can release far more dopamine than can cocaine or other addictive drugs.[26][37]

Serotonin

Amphetamine has been found to exert similar effects on serotonin as on dopamine.[38] Like DAT, the serotonin transporter SERT can be induced to operate in reverse upon stimulation by amphetamine.[39] This mechanism is thought to rely on the actions of calcium ions, as well as on the proximity of certain transporter proteins.[39]

The interaction between amphetamine and serotonin is apparent only in particular regions of the brain, such as the mesocorticolimbic projection. Recent studies additionally postulate that amphetamine may indirectly alter the behavior of glutamatergic pathways extending from the ventral tegmental area to the prefrontal cortex.[38] Glutamatergic pathways are strongly correlated with increased excitability at the level of the synapse. Increased extracellular concentrations of serotonin may thus modulate the excitatory activity of glutamatergic neurons.[38]

The proposed ability of amphetamine to increase excitability of glutamatergic pathways may be of significance when considering serotonin-mediated addiction.[38] An additional behavioral consequence may be the stereotyped locomotor stimulation that occurs in response to amphetamine exposure.[27]

Other relevant neurotransmitters

Several other neurotransmitters have been linked to amphetamine activity. For instance, extracellular levels of glutamate, the primary excitatory neurotransmitter in the brain, have been shown to increase upon exposure to amphetamine. Consistent with other findings, this effect was found in the areas of the brain implicated in reward; namely, the nucleus accumbens, striatum, and prefrontal cortex. In addition, several studies demonstrate increased levels of norepinephrine, a neurotransmitter related to adrenaline, in response to amphetamine. This is believed to occur via reuptake blockage as well as via interactions with the norepinephrine neuronal transport carrier.[40] The long-term effects of amphetamines use on neural development in children has not been well established.[41] Based on a study in rats, amphetamine use during adolescence may impair adult working memory.[42]

Pharmacology

Chemical properties

Molecular structure of amphetamine. Methamphetamine has the same structure, with the addition of a methyl group attached to the nitrogen.
Chart comparing the chemical structures of different amphetamine derivatives.

Amphetamine is a chiral compound. The racemic mixture can be divided into its optical isomers: levo- and dextro-amphetamine. Amphetamine is the parent compound of its own structural class, comprising a broad range of psychoactive derivatives, from empathogens, MDA (3,4-Methylenedioxyamphetamine) and MDMA (3,4-Methylenedioxy-N-methamphetamine) known as ecstasy, to the N-methylated form, methamphetamine known as 'meth', and to decongestants such as ephedrine (EPH) . Amphetamine is a homologue of phenethylamine.

At first, the medical drug came as the salt racemic-amphetamine sulfate (racemic-amphetamine contains both isomers in equal amounts). Attention disorders are often treated using Adderall or a generic equivalent, a formulation of mixed amphetamine and dextroamphetamine salts that contain

  • 1/4 dextro-amphetamine saccharate
  • 1/4 dextro-amphetamine sulfate
  • 1/4 (racemic amphetamine) aspartate monohydrate
  • 1/4 (racemic amphetamine) sulfate

Pharmacodynamics

Amphetamine has been shown to both diffuse through the cell membrane and travel via the dopamine transporter (DAT) to increase concentrations of dopamine in the neuronal terminal.

Amphetamine, both as d-amphetamine (dextroamphetamine) and l-amphetamine (or a racemic mixture of the two isomers), is believed to exert its effects by binding to the monoamine transporters and increasing extracellular levels of the biogenic amines dopamine, norepinephrine (noradrenaline) and serotonin. It is hypothesized that d-amphetamine acts primarily on the dopaminergic systems, while l-amphetamine is norepinephrinergic (noradrenergic). The primary reinforcing and behavioral-stimulant effects of amphetamine, however, are linked to enhanced dopaminergic activity, primarily in the mesolimbic dopamine system.

Amphetamine and other amphetamine-type stimulants act principally to release dopamine into the synaptic cleft. Amphetamine, unlike dopamine transporter inhibitor cocaine, acts as a substrate for DAT and slows reuptake by a secondary acting mechanism through the phosphorylation of dopamine transporters.[43] A primary action of amphetamine is mediated by vesicular monoamine transporters (VMATs); the transporters appear to provide a channel through which dopamine and other transmitters can exit the vesicle to the cytosol. According to the "weak base hypothesis" this is exacerbated by amphetamine acting to alkalinize the vesicle, which depletes the free energy favoring vesicle accummlation so that transmitter is redistributed to the cytosol. Together, these actions cause the release of dopamine, norepinephrine, and serotonin from monoamine vesicles, thereby increasing cytosolic concentrations of transmitter. This increase in concentration assists in the "reverse transport" of dopamine via the dopamine transporter (DAT) into the synapse.[44] In addition, amphetamine binds reversibly to the DATs and blocks the transporter's ability to clear DA from the synaptic space. Amphetamine also acts in this way with norepinephrine (noradrenaline) and to a lesser extent serotonin.

In addition, amphetamine binds to a group of receptors called Trace Amine Associated Receptors (TAAR).[45] TAAR are a newly discovered receptor system that seems to be affected by a range of amphetamine-like substances called trace amines.

History

Amphetamine was first synthesized in 1887 by the Romanian chemist Lazăr Edeleanu in Berlin, Germany.[46] He named the compound phenylisopropylamine. It was one of a series of compounds related to the plant derivative ephedrine, which had been isolated from Ma-Huang that same year by Nagayoshi Nagai.[47] No pharmacological use was found for amphetamine until 1927, when pioneer psychopharmacologist Gordon Alles resynthesized and tested it on himself, in search of an artificial replacement for ephedrine. From 1933 or 1934 Smith, Kline and French began selling the volatile base form of the drug as an inhaler under the trade name Benzedrine, useful as a decongestant but readily usable for other purposes.[48] One of the first attempts at using amphetamine as a scientific study was done by M. H. Nathanson, a Los Angeles physician, in 1935. He studied the subjective effects of amphetamine in 55 hospital workers who were each given 20 mg of Benzedrine. The two most commonly reported drug effects were "a sense of well being and a feeling of exhilaration" and "lessened fatigue in reaction to work".[49] During World War II amphetamine was extensively used to combat fatigue and increase alertness in soldiers. After decades of reported abuse, the FDA banned Benzedrine inhalers, and limited amphetamine to prescription use in 1965, but non-medical use remained common. Amphetamine became a schedule II drug in the USA under the Controlled Substances Act in 1971.

The related compound methamphetamine was first synthesized from ephedrine in Japan in 1920 by chemist Akira Ogata, via reduction of ephedrine using red phosphorus and iodine. The pharmaceutical Pervitin was a tablet of 3 mg methamphetamine that was available in Germany from 1938 and widely used in the Wehrmacht, but by mid-1941 it became a controlled substance, partly because of the amount of time needed for a soldier to rest and recover after use and partly because of abuse. For the rest of the war, military doctors continued to issue the drug, but less frequently and with increasing discrimination.[50]

In 1997 and 1998,[51][52] researchers at Texas A&M University claimed to have found amphetamine and methamphetamine in the foliage of two Acacia species native to Texas, A. berlandieri and A. rigidula. Previously, both of these compounds had been thought to be human inventions. These findings have never been duplicated, and the analyses are believed by many biochemists to be the result of experimental error, and as such the validity of the report has come into question. Alexander Shulgin, one of the most experienced biochemical investigators and the discoverer of many new psychotropic substances, has tried to contact the Texas A&M researchers and verify their findings. The authors of the paper have not responded; natural amphetamine remains an unconfirmed discovery.[53]

Performance-enhancing use

Adderall, an amphetamine mixture, is used by some college and high-school students as a study and test-taking aid.[54] Amphetamine works by increasing energy levels, concentration, and motivation, thus allowing students to study for an extended period of time.

Amphetamine has been, and is still, used by militaries around the world. British troops used 72 million amphetamine tablets in the second world war[55] and the RAF used so many that "Methedrine won the Battle of Britain" according to one report.[56] American bomber pilots use amphetamine ("go pills") to stay awake during long missions. The Tarnak Farm incident, in which an American F-16 pilot killed several friendly Canadian soldiers on the ground, was blamed by the pilot on his use of amphetamine.[57] A nonjudicial hearing rejected the pilot's claim.[citation needed]

Amphetamine is also used by some professional,[58] collegiate[59] and high school[59] athletes for its strong stimulant effect. Energy levels are perceived to be dramatically increased and sustained, which is believed to allow for more vigorous and longer play. However, at least one study has found that this effect is not measurable.[60] The use of amphetamine during strenuous physical activity can be extremely dangerous, especially when combined with alcohol, and athletes have died as a result, for example, British cyclist Tom Simpson.

Amphetamine use has historically been especially common among Major League Baseball players and is usually known by the slang term "greenies".[61] In 2006, the MLB banned the use of amphetamine. The ban is enforced through periodic drug-testing. However, the MLB has received some criticism because the consequences for amphetamine use are dramatically less severe than for anabolic steroid use, with the first offense bringing only a warning and further testing.[62][63][64]

Amphetamine was formerly in widespread use by truck drivers[65] to combat symptoms of somnolence and to increase their concentration during driving, especially in the decades prior to the signing by former president Ronald Reagan of Executive Order 12564, which initiated mandatory random drug testing of all truck drivers and employees of other DOT-regulated industries. Although implementation of the order on the trucking industry was kept to a gradual rate in consideration of its projected effects on the national economy, in the decades following the order, amphetamine and other drug abuse by truck drivers has since dropped drastically. (See also Truck driver—Implementation of drug detection).

Detection in body fluids

Amphetamine is frequently measured in urine as part of a drug abuse testing program, in plasma or serum to confirm a diagnosis of poisoning in hospitalized victims, or in whole blood to assist in the forensic investigation of a traffic or other criminal violation or a case of sudden death. Techniques such as immunoassay may cross-react with a number of sympathomimetics drugs, so chromatographic methods specific for amphetamine should be employed to prevent false positive results. Chiral techniques may be employed to help distinguish the source of the drug, whether obtained legally (via prescription) or illicitly, or possibly as a result of formation from a prodrug such as lisdexamfetamine or selegiline. Chiral separation is needed to assess the possible contribution of l-methamphetamine (Vicks Inhaler) toward a positive test result.[66][67][68]

Society and culture

From the 1960s onward, amphetamine has been popular with many youth subcultures in Britain (and other parts of the world) as a recreational drug. It has been commonly used by mods, skinheads, punks, goths, gangsters, and casuals in all night soul and ska dances, punk concerts, basement shows and fighting on the terraces by casuals. [citation needed]

The hippie counterculture was very critical of amphetamines due to the behaviors they cause; in an interview with the Los Angeles Free Press in 1965, beat writer Allen Ginsberg commented that "Speed is antisocial, paranoid making, it's a drag... all the nice gentle dope fiends are getting screwed up by the real horror monster Frankenstein speed freaks who are going round stealing and bad-mouthing everybody".[69]

In literature

The writers of the Beat Generation used amphetamine extensively, mainly under the Benzedrine brand name. Jack Kerouac was a particularly avid user of amphetamine, which was said to provide him with the stamina needed to work on his novels for extended periods of time.[70]

Scottish author Irvine Welsh often portrays drug use in his novels, though in one of his journalism works he comments on how drugs (including amphetamine) have become part of consumerism and how his novels Trainspotting and Porno reflect the changes in drug use and culture during the years that elapse between the two texts.[71]

Amphetamine is frequently mentioned in the work of American journalist Hunter S. Thompson. Speed not only appears among the inventory of drugs Thompson consumed for what could broadly be defined as recreational purposes but also receives frequent, explicit mention as an essential component of his writing toolkit,[72] such as in his "Author's Note" in Fear and Loathing on the Campaign Trail '72.[73]

"One afternoon about three days ago [the publishers] showed up at my door with no warning, and loaded about forty pounds of supplies into the room: two cases of Mexican beer, four quarts of gin, a dozen grapefruits, and enough speed to alter the outcome of six Super Bowls. ... Meanwhile, [...] with the final chapter still unwritten and the presses scheduled to start rolling in twenty-four hours . . . . unless somebody shows up pretty soon with extremely powerful speed, there might not be a final chapter. About four fingers of king-hell Crank would do the trick, but I am not optimistic."

In music

Many songs have been written about amphetamine, for example in the track entitled "St. Ides Heaven" from singer/songwriter, Elliott Smith's self-titled album. Semi Charmed Life by Third Eye Blind also references amphetamine. Another blatant example would be the song simply labelled "Amphetamine" by Alternative rock band Everclear, the song "20 Dollar nose bleed" by the Pop-rock band Fall Out Boy, and the song Headfirst For Halos by My Chemical Romance. It has also influenced the aesthetics of many rock'n'roll bands (especially in the garage rock, mod R&B, death rock, punk/hardcore, gothic rock and extreme heavy metal genres). Hüsker Dü, Jesus and Mary Chain's and The Who were keen amphetamine users early in their existence. Land Speed Record is an allusion to Hüsker Dü's amphetamine use. [citation needed] Amphetamine was widely abused in the 1980s underground punk-rock scene. Pop-punk band NOFX have incorporated references to Amphetamines and other stimulants, the two most obvious being the song "Three on Speed" from the "Surfer" 8" LP (in reference to the three guys being on Amphetamine while recording the album), and earlier the album "The Longest Line" is in reference to a "line" of Amphetamine ready for insufflation. The Rolling Stones referenced the drug in their song "Can't You Hear Me Knocking" on the album Sticky Fingers ("Y'all got cocaine eyes / Yeah, ya got speed-freak jive now"). Lou Reed refers explicitly to the drug on his album Berlin, in the song "How Do You Think It Feels?". Reed's band The Velvet Underground, a creation of Andy Warhol's Factory Years, was fueled by amphetamines, as well as naming their second album White Light/White Heat after the drug and making reference to the song in "Sister Ray.". The Pulp song Sorted for E's & Wizz refers to British slang terms for ecstasy and amphetamines.

Many rock'n'roll bands have named themselves after amphetamine and drug slang surrounding it. For example Mod revivalists, The Purple Hearts named themselves after the amphetamine tablets popular with mods during the 1960s, as did the Australian band of the same name during the mid-1960s. [citation needed] The Amphetameanies, a ska-punk band, are also named after amphetamine, but also imitate its effects. Dexy's Midnight Runners, of number one hit "Come On Eileen", are named after Dexedrine. Motörhead derived their name from the British slang for 'speed freak' and Motorhead's Lemmy Kilmister is a long-term user of speed.

An American electronic music duo The Crystal Method has a reference to methamphetamine (Crystal Meth) in its name.

A hip hop artist by the name of Yelawolf references Adderall in his song "Billy Crystal" featuring Rock City off of his album "Trunk Muzik 0-60".

The Northern Soul scene, a offshoot of the mods, had people taking amphetamines to keep dancing all night. One DJ, Roger Eagle, got out of the Northern Soul scene saying: "All they wanted was fast-tempo black dance music... [but they were] too blocked on amphetamines to articulate exactly which Jackie Wilson record they wanted me to play."[74]

In film

Producer David O. Selznick was an amphetamine user, and would often dictate long and rambling memos under the influence of amphetamine to his directors.[75] The documentary Shadowing The Third Man relates that Selznick introduced The Third Man director Carol Reed to the use of amphetamine, which allowed Reed to bring the picture in below budget and on schedule by filming nearly 22 hours at a time.[76]


The title of the 2009 movie Amphetamine plays on the double meaning of the word in Chinese - besides the name for the drug it also means 'isn't this his fate?' which figuratively ties to the movie's plot. The word is transliterated as 安 非 他 命 - "ān fēi tā mìng" - and as commonly happens with transliteration of non-Chinese terms each character has independent meaning as an individual unrelated word.

  • In the United Kingdom, amphetamines are regarded as Class B drugs. The maximum penalty for unauthorized possession is five years in prison and an unlimited fine. The maximum penalty for illegal supply is 14 years in prison and an unlimited fine.[77]
  • In the Netherlands, amphetamine and methamphetamine are List I drugs of the Opium Law, but the dextro isomer of amphetamine is indicated for ADD/ADHD and narcolepsy and available for prescription as 5 and 10 mg generic tablets, and 5 and 10 mg gel capsules.
  • In the United States, amphetamine and methamphetamine are Schedule II drugs, classified as CNS (central nervous system) stimulants.[78] A Schedule II drug is classified as one that has a high potential for abuse, has a currently-accepted medical use and is used under severe restrictions, and has a high possibility of severe psychological and physiological dependence.
  • In Canada, possession of amphetamines is a criminal offence under Schedule III of the Controlled Drugs and Substances Act, with a maximum penalty for repeat offenders of fines of up to $2,000, imprisonment for up to one year, or both.[79]

Internationally, amphetamine is a Schedule II drug under the Convention on Psychotropic Substances.[80]

Prodrugs

A number of substances have been shown to produce amphetamine and/or methamphetamine as metabolites, including amfecloral, amphetaminil, benzphetamine, clobenzorex, dimethylamphetamine, ethylamphetamine, famprofazone, fencamine, fenethylline, fenproporex, furfenorex, lisdexamfetamine, mefenorex, mesocarb, prenylamine, propylamphetamine, and selegiline, among others.[81][82] These compounds may produce positive results for amphetamine on drug tests.[81][82]

Derivatives

Amphetamine derivatives are a class of potent drugs that act by increasing levels of dopamine and norepinephrine in the brain, inducing euphoria.[83][84][85] The class includes prescription CNS drugs commonly used to treat attention-deficit hyperactivity disorder (ADHD). It is also used to treat symptoms of traumatic brain injury (TBI) and the daytime drowsiness symptoms of narcolepsy, postural orthostatic tachycardia syndrome (POTS) and chronic fatigue syndrome (CFS).

Smuggling

The 213 kg of amphetamine worth 40 million AED was seized by the UAE Drug combat authorities, on 30 November 2011 from an Iranian ship that was supposed to deliver the consingment in Malaysia and made a port stop in Sharjah.

The Gulf News published on 30th November 2011, says "This is the biggest drug bust of its kind in 2011 and the second big one in the last three years worldwide," said Dr Wadia Maalouf, International expert at the United Nation's Drug and Crime office.[86]

Shortage

As of November 2011 there is a general shortage of Amphetamine in the United States.

Rockville, MD: National Institute on Drug Abuse. pp. 47–67. This study has provided the first objective data regarding the use of potentially abusive drugs by tractor-trailer drivers... Prescription stimulants, such as amphetamine, methamphetamine, and phentermine were found in 5 percent of the [317] drivers [who participated in the study], often in combination with similar but less potent stimulants, such as phenylpropanolamine. Nonprescription stimulants were detected in 12 percent of the drivers, about half of whom gave no medical explanation for their presence... One limitation of these findings is that 12 percent of the randomly selected drivers refused to participate in the study or provided insufficient urine and blood for testing; the distribution of drugs among these 42 drivers is unknown... Finally, the results apply to tractor-trailer drivers operating on a major east-west interstate route in Tennessee. Drug incidence among other truck-driver populations are unknown and may be higher or lower than reported here.
