The safety ratios of common recreational drugs are shown in Table 5.2 Popular Recreational Drugs and Their Safety Ratios. Opioids, including codeine, opium, morphine and heroin, produce euphoria and analgesia by increasing activity in opioid receptor neurons. In the United States, benzodiazepines are among the most widely prescribed medications that affect the CNS.

Facial tics. Using illegal drugs usually poses a higher risk. Current Directions in Psychological Science, 2(5), 148152; Bushman, B. J. Alcohol also influences aggression through expectations. Heart failure: Could a low sodium diet sometimes do more harm than good? MDMA is a very strong stimulant that very successfully prevents the reuptake of serotonin, dopamine, and norepinephrine. In higher doses, alcohol acts on the cerebellum to interfere with coordination and balance, producing the staggering gait of drunkenness. (1984). It is much less likely to lead to antisocial acts than that other popular intoxicant, alcohol, and it is also the one psychedelic drug whose use has not declined in recent years (National Institute on Drug Abuse, 2009).

In the late 19th and early 20th centuries, it was a primary constituent in many popular tonics and elixirs and, although it was removed in 1905, was one of the original ingredients in Coca-Cola. This class of psychoactive drugs includes ketamine and PCP (phenyl cyclohexyl piperidine or phencyclidine).

Can poor sleep impact your weight loss goals? Hallucinogens like mushrooms, LSD, DMT, and ayahuasca affect the brain differently.
