Methamphetamine is a stimulant that the source describes in powder, pill, and crystal forms, with several routes of use. The overview discusses dopamine effects, short- and long-term health consequences, and research on changes in cognition, memory, and brain function associated with prolonged use.
Cocaine is described as an addictive stimulant that may be snorted, rubbed on the gums, injected, or smoked as crack. The overview covers its effects on the brain and body, risks associated with repeated use or adulterated supply, and treatment approaches discussed in the source.
MDMA, also called Ecstasy or Molly, is described as a synthetic drug that affects mood, perception, energy, and sensory experience. The source outlines common forms of use, changes to dopamine, norepinephrine, and serotonin activity, and reported short- and longer-term health effects.
The article reviews evidence that high-dose amphetamine or methamphetamine can produce a paranoid psychosis, sometimes with hallucinations, in a clear state of consciousness. Historical case reports and experimental studies describe varied courses after drug cessation, including rapid remission and, in some cases, prolonged vulnerability or recurrence.
The article surveys research and case reports linking cannabis use, including synthetic cannabinoids, with psychotic experiences and other psychiatric symptoms. It summarizes longitudinal evidence associating regular or heavy cannabis use with increased psychosis risk, while emphasizing that observational findings leave uncertainty about causation and individual vulnerability.
This resource compiles information about zolpidem (Ambien), including reported medication interactions and labeled effects on alertness, memory, and coordination. Its interaction summaries describe possible increased drowsiness, confusion, and impaired judgment when zolpidem is combined with alcohol or other medicines, while the included product-label material reports study findings on next-day effects.
This resource reviews laboratory research on alcohol’s acute effects on memory in healthy adults, including working, episodic, and semantic memory. The cited experiments report that effects differ by task and timing: alcohol can impair encoding and some forms of recall while leaving implicit memory or priming relatively unaffected, and findings vary across the blood-alcohol curve.
