Amphetamine is a central nervous system (CNS) stimulant that is used in the treatment of attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity. Amphetamine was discovered as a chemical in 1887 by Lazăr Edeleanu, and then as a drug in the late 1920s. It exists as two enantiomers: levoamphetamine and dextroamphetamine. Amphetamine properly refers to a specific chemical, the racemic free base, which is equal parts of the two enantiomers in their pure amine forms. The term is frequently used informally to refer to any combination of the enantiomers, or to either of them alone. Historically, it has been used to treat nasal congestion and depression. Amphetamine is also used as an athletic performance enhancer and cognitive enhancer, and recreationally as an aphrodisiac and euphoriant. It is a prescription drug in many countries, and unauthorized possession and distribution of amphetamine are often tightly controlled due to the significant health risks associated with recreational use.
3,4-Methylenedioxymethamphetamine (MDMA), commonly known as ecstasy, and molly or mandy, is a potent empathogen–entactogen with stimulant and minor psychedelic properties primarily used for recreational purposes. The purported pharmacological effects that may be prosocial include altered sensations, increased energy, empathy, and pleasure. When taken by mouth, effects begin in 30 to 45 minutes and last three to six hours.

Dextroamphetamine is a potent central nervous system (CNS) stimulant and enantiomer of amphetamine that is prescribed for the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. It is also used as an athletic performance and cognitive enhancer, and recreationally as an aphrodisiac and euphoriant.
Adderall and Mydayis are trade names for a combination drug called mixed amphetamine salts containing four salts of amphetamine. The mixture is composed of equal parts racemic amphetamine and dextroamphetamine, which produces a (3:1) ratio between dextroamphetamine and levoamphetamine, the two enantiomers of amphetamine. Both enantiomers are stimulants, but differ enough to give Adderall an effects profile distinct from those of racemic amphetamine or dextroamphetamine, which are marketed as Evekeo and Dexedrine/Zenzedi, respectively. Adderall is used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. It is also used illicitly as an athletic performance enhancer, cognitive enhancer, appetite suppressant, and recreationally as a euphoriant. It is a central nervous system (CNS) stimulant of the phenethylamine class.
Unani or Yunani medicine is Perso-Arabic traditional medicine as practiced in Muslim culture in South Asia and modern day Central Asia. Unani medicine is pseudoscientific. The Indian Medical Association describes Unani practitioners who claim to practice medicine as quacks.
Stanley Norman Cohen is an American geneticist and the Kwoh-Ting Li Professor in the Stanford University School of Medicine. Stanley Cohen and Herbert Boyer were the first scientists to transplant genes from one living organism to another, a fundamental discovery for genetical engineering. Thousands of products have been developed on the basis of their work, including human growth hormone and hepatitis B vaccine. According to immunologist Hugh McDevitt, "Cohen's DNA cloning technology has helped biologists in virtually every field". Without it, "the face of biomedicine and biotechnology would look totally different." Boyer cofounded Genentech in 1976 based on their work together, but Cohen was a consultant for Cetus Corporation and declined to join. In 2022, Cohen was found guilty of having committed fraud in misleading investors into a biotechnology company he founded in 2016, and paid $29 million in damages.

Substituted amphetamines are a class of compounds based upon the amphetamine structure; it includes all derivative compounds which are formed by replacing, or substituting, one or more hydrogen atoms in the amphetamine core structure with substituents. The compounds in this class span a variety of pharmacological subclasses, including stimulants, empathogens, and hallucinogens, among others. Examples of substituted amphetamines are amphetamine (itself), methamphetamine, ephedrine, cathinone, phentermine, mephentermine, tranylcypromine, bupropion, methoxyphenamine, selegiline, amfepramone (diethylpropion), pyrovalerone, MDMA (ecstasy), and DOM (STP).
Gordon A. Alles, was an American chemist and pharmacologist who did extensive research on the isolation and properties of insulin for the treatment of diabetics. He is also credited with discovering and publishing the physiological effects of amphetamine and methylenedioxyamphetamine (MDA). He is the first person to have prepared amphetamine sulfate, although not the amphetamine molecule. Alles first reported the physiological properties of amphetamine as a synthetic analog of ephedrine, and therefore received credit for this discovery. He enjoyed large royalties from Smith, Kline & French (SKF) because he sold his patent rights for amphetamine to the company and it enjoyed large sales. Several popular products sold by SKF contained amphetamine, including Benzedrine pills and inhalers, Dexedrine pills and Dexamyl tablets. Counterfeit drugs such as Profetamine appeared, aiming to circumvent Alles' 'weak' patent.
