Question

Quizplus · Accepted Answer

Frequent drug use can lead to changes in the brain that result in strong cravings for the drug when situations trigger memories of drug use. This can be a significant risk factor for relapse and continued drug use. Additionally, drug use can lead to decreased sensitivity to the effects of the drug, or tolerance, rather than decreased tolerance as implied in option B. Increased REM sleep (option A) is not a typical effect of drug use, and increased behavioral inhibitions (option C) would be an unexpected outcome of the disinhibiting effects of many drugs.
