Amphetamines belong to the psychostimulant drug class and result in increased mental activity. Illicit amphetamines like speed are also snorted or smoked using a pipe. Although amphetamine and methamphetamine pills can be swallowed, pills and powder may be dissolved in water and injected, especially when taken illicitly. Amphetamines are highly addictive stimulants that are used for the treatment of ADHD. Protection against methamphetamine-induced neurotoxicity has also been observed following administration of ascorbic acid (vitamin C), cobalamin (vitamin B12), and vitamin E. It has also been found that TBI patients testing positive for methamphetamine at the time of emergency department admission have lower rates of mortality.

Paying for Treatment

Alcohol and other depressants can counteract some of the side effects that occur due to the stimulation of the central nervous system. In long-term users, consistently high blood pressure or heart rate can increase the risk for heart attack and other serious complications. Although these substances are effective when used as prescribed, some of these effects can be life-threatening. Amphetamines usually produce physical and psychological side effects within minutes.

Dental and oral health (“meth mouth”)

Services such as counseling, behavioral therapy, and medication-assisted treatment (MAT) can help patients detox from amphetamines. Fortunately, there are many addiction treatment centers that provide quality rehabilitation services for amphetamine abuse. Amphetamine withdrawal refers to the range of symptoms that can occur when a person stops taking amphetamines after using them for a prolonged period of time.

• One explanation could be that amphetamine induced behaviour is enhanced by the presence of oestrogen, whereas testicular hormones may have the opposite effect.28 Another possibility is that women arrested for illicit amphetamine use were particularly disadvantaged in comparison with men, with higher levels of trauma, lack of psychosocial support and stigma.29
• Two studies reviewed examined dexamphetamine as stimulant agonist treatment.
• Amphetaminenote 2 is a central nervous system (CNS) stimulant that is used in the treatment of attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity; it is also used to treat binge eating disorder in the form of its inactive prodrug lisdexamfetamine.
• Care may be delivered through outpatient services (e.g., RAAM clinics) or residential rehab treatment with structured therapy and aftercare.
• If reported in the studies, secondary outcome measures were also considered for inclusion (see Box 1).

In the state of Florida, among the deaths investigated by the state medical examiners in 2016, there was an increase in the presence of amphetamine (65%) and methamphetamine (104%) at the time of death. Amphetamine addiction is generally caused by using high doses of amphetamine. zoloft and pepcid After an initial incidence of drug-induced psychosis, psychological stress may be sufficient to trigger a psychotic episode even during abstinence. Amphetamine-induced psychosis may also occur due to long-term use of the drug. The stimulating effects of amphetamine may allow consumption of higher volumes of alcohol and result in liver and muscle damage.

Signs and Symptoms of Amphetamine Use and Addiction

The presentation of these symptoms may manifest in and mimic many different mental disorders aside from singularly ADHD itself (28). The 1997 clarification by the FDA broadcast regulations allowed for Schedule II drugs to be advertised directly to consumers (13). During the following years of the 1960s, FDA estimates of amphetamine production would grow little beyond 8 billion 10-mg doses, implying that consumption of the drug had already reached saturation levels in 1962 (20). Addiction involves a loss of control of use, meaning that many pharmaceutical companies benefit from the increase in demand of these drugs as well as their use outside of the prescribed amount and off-label uses.

The 6 Stages of Mental Health Recovery

Owing to the effect pH has on absorption, proton pump inhibitors, which reduce gastric acid, are known to interact with methamphetamine. Specifically, acidic substances will reduce the absorption of methamphetamine and increase urinary excretion, while alkaline substances do the opposite. The pH of gastrointestinal content and urine affects the absorption and excretion of methamphetamine. Methamphetamine may counteract the effects of antihypertensives and antipsychotics owing to its effects on the cardiovascular system and cognition respectively. Methamphetamine also interacts with monoamine oxidase inhibitors (MAOIs), since both MAOIs and methamphetamine increase plasma catecholamines; therefore, concurrent use of both is dangerous.

Similar to its therapeutic effect in ADHD, dextroamphetamine enhances cognitive control and may reduce impulsivity in patients with BED by enhancing the cognitive processes responsible for overriding prepotent feeding responses that precede binge eating episodes. Centrally, dextroamphetamine increases neurotransmitter activity of dopamine and norepinephrine in prefrontal cortical regions that regulate cognitive control of behavior. Binge eating disorder (BED) is characterized by recurrent and persistent episodes of compulsive binge eating. Children with ADHD who use stimulant medications generally have better relationships with peers and family members, perform better in school, are less distractible and impulsive, and have longer attention spans. Stimulants like methylphenidate and amphetamine are effective in treating ADHD because they increase neurotransmitter activity in these systems.

Evidence suggests that lisdexamfetamine’s treatment efficacy in BED is underpinned at least in part by a psychopathological overlap between BED and ADHD, with the latter conceptualized as a cognitive control disorder that also benefits from treatment with lisdexamfetamine. One review highlighted a nine-month randomized controlled trial of amphetamine treatment for ADHD in children that found an average increase of 4.5 IQ points, continued increases in attention, and continued decreases in disruptive behaviors and hyperactivity. Additionally, a 2024 meta-analytic systematic review reported moderate improvements in quality of life when amphetamine treatment is used for ADHD. Long-term amphetamine exposure at sufficiently high doses in some animal species is known to produce abnormal dopamine system development or nerve damage, but, in humans with ADHD, long-term use of pharmaceutical amphetamines at therapeutic doses appears to improve brain development and nerve growth. Recreational doses are generally much larger than prescribed therapeutic doses and carry a far greater risk of serious side effects.sources 3

While these drugs are prescribed for legitimate medical conditions like ADHD and narcolepsy, their misuse and abuse can result in severe addiction. Similar to other CNS stimulants like MDMA (Molly), using amphetamines to suppress appetite or reduce fatigue can trigger a dangerous cycle of repeated use, culminating in dependence and addiction. Sometimes informally known as smart drugs or club drugs, amphetamines are popular among younger adults who consider them accessible and safer than substances like heroin or meth.

In the March 19, 2025, issue of JAMA, National Institute on Drug Abuse researcher Beth Han and colleagues examined prevalence and patterns of prescription stimulant use, misuse, and disorders among U.S. adults. Chronic misuse of stimulants can result in mood swings, depression, irritability, and even psychosis. No matter where you live, there is a drug rehab center that can help you overcome your addiction.

Methamphetamine use was found to be related to higher frequencies of unprotected sexual intercourse in both HIV-positive and unknown casual partners, an association more pronounced in HIV-positive participants. The crash following the use of methamphetamine in this manner is very often severe, with marked hypersomnia (excessive daytime sleepiness). Because of its strong stimulant and aphrodisiac effects and inhibitory effect on ejaculation, with repeated use, these sexual encounters will sometimes occur continuously for several days on end. Participants in this subculture, which consists almost entirely of homosexual male methamphetamine users, will typically meet up through internet dating sites and have sex.

• The risk of bias of the included studies was assessed with the Cochrane tool, and the strength of evidence with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
• Symptoms of amphetamine overdose involve many of the symptoms observed after acute amphetamine use but are more severe.
• Our team does their best for our readers to help them stay informed about vital healthcare decisions.
• Amphetamine has also been shown to produce a conditioned place preference in humans taking therapeutic doses, meaning that individuals acquire a preference for spending time in places where they have previously used amphetamine.
• While abuse of amphetamine drugs is very prevalent in younger people, deaths were most likely to occur in those aged between 45 and 54 years of age.

Here we review studies reporting on pharmacotherapies for the treatment of SUD or drug dependence due to AMPH/MA. Globally, it is estimated that 7.4 million people are dependent on amphetamines, and that dependence affects 11% of people who use amphetamines . The stimulant (or a closely related substance) is taken to relieve or avoid withdrawal symptoms The effects of chronic and regular high-dose AMPH/MA use are more complex than occasional use, and may involve the development of a substance use disorder—characterised by social and physiological (e.g. tolerance, withdrawal) manifestations . Amphetamines refer to both amphetamine (AMPH) and the structurally similar methamphetamines (MA), both of which are used extra-medically. Approximately 29 million people worldwide aged 15–65 years were estimated to have consumed amphetamines in the past year to 2017 .

In addition, both a review and a hydroxyzine hcl oral uses meta-analytic systematic review found lisdexamfetamine to be superior to placebo in several secondary outcome measures, including persistent binge eating cessation, reduction of obsessive-compulsive related binge eating symptoms, reduction of body-weight, and reduction of triglycerides. Dextroamphetamine also activates TAAR1 in peripheral organs along the gastrointestinal tract that are involved in the regulation of food intake and body weight. Moreover, dextroamphetamine induces synthesis of the cocaine- and amphetamine-regulated transcript (CART), a peptide neurotransmitter that regulates food intake. Through noradrenergic signaling pathways, dextroamphetamine triggers lipolysis in adipose fat cells, thereby prompting the release of triglycerides into blood plasma to be utilized as a fuel substrate.

In spite of strict government controls, amphetamine has been used legally or illicitly by people from a variety of backgrounds, including authors, musicians, mathematicians, and athletes. As the addictive properties of the drug became known, governments began to place strict controls on the sale of amphetamine. Amphetamine was first synthesized in 1887 in Germany by Romanian chemist Lazăr Edeleanu who named it phenylisopropylamine; its stimulant effects remained unknown until 1927, when it was independently resynthesized do people snort ambien by Gordon Alles and reported to have sympathomimetic properties.
