Responsible drug use seeks to maximize the benefits and minimize the risks associated with psychoactive drug use. For illegal psychoactive drugs that are not diverted prescription controlled substances, some critics[1][2] believe that illegal recreational drug use is inherently irresponsible, due to the unpredictable and unmonitored strength and purity of the drugs and the risks of addiction, infection, and other side effects.
Nevertheless, harm reduction advocates claim that the user can be responsible by employing the same general principles applicable to the use of alcohol: avoiding hazardous situations, excessive doses, and hazardous combinations of drugs; avoiding injection; and not using drugs at the same time as activities that may be unsafe without a sober state.[3] Drug use can be thought of as an activity that is potentially beneficial but also potentially risky. Similar to other risky activities such as skydiving or mountain climbing, the varied risks of drug use can be minimized by using harm-reduction strategies such as education, caution, and common sense. These advocates also point out that government action (or inaction) makes responsible drug use more difficult by artificially increasing risks, such as by making drugs of known purity and strength unavailable due to prohibition.
