| addiction | Addiction is a state of psychological or physical dependence (or both) on the use of alcohol or other drugs. |
| tolerance | A form of neuroadaptation. The diminishing effect with regular use of the same dose of a drug, requiring the user to take larger and larger doses before experiencing the drug's effect. |
| withdrawal | A form of neuroadaptation. The discomfort and distress that follow discontinuing an addictive drug or behaviour. |
| depressants | Drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions. |
| alcohol use disorder | (popularly known as "alcoholism") Alcohol use marked by tolerance, withdrawal, and a drive to continue problematic use. |
| barbiturates | Drugs that depress central nervous system activity, reduce anxiety but impair memory and judgment. |
| opioids | Opium and its derivatives such as morphine and heroin; depress neural activity, temporarily lessening pain and anxiety. |
| stimulants | Drugs (such as caffeine, nicotine, cocaine, amphetamines, methamphetamine, and Ecstasy. They excite neural activity and speed up body functions. |
| nicotine | A stimulating and highly addictive psychoactive drug in tobacco. |
| cocaine | A powerful and addictive stimulant derived from the coca plant. Produces temporarily increased alertness and euphoria. |
| amphetamines | Drugs, such as methamphetamine, that stimulate neural activity, causing accelerated body functions and associated energy and mood changes. |
| methamphetamine | A powerfully addictive drug that stimulates the central nervous system, with accelerated body functions and associated energy and mood changes; over time, appears to reduce baseline dopamine levels. |
| Ecstasy (MDMA) | A synthetic stimulant and mild hallucinogen. Produces euphoria and social intimacy, but with short-term health risks and longer-term harm to serotonin-producing neurons and to mood and cognition. |
| hallucinogens | Psychedelic ("mind-manifesting") drugs, such as LSD, that distorts perceptions and evoke sensory images in the absence of sensory input. |
| near-death experience | An altered state of consciousness reported after a close brush death (such as cardiac arrest); often similar to drug-induced hallucinations. |
