Document Summary
Our concern about the use of a substance depends on: who"s usi(cid:374)g it, ho(cid:449) (cid:373)u(cid:272)h, a(cid:374)d (cid:449)he(cid:374), (cid:449)here, a(cid:374)d (cid:449)h(cid:455) it is (cid:271)ei(cid:374)g used. Use is not abuse: most users of a(cid:374)(cid:455) gi(cid:448)e(cid:374) su(cid:271)sta(cid:374)(cid:272)e do(cid:374)"t use it i(cid:374) (cid:449)a(cid:455)s that (cid:272)a(cid:374) (cid:271)e defined as abuse or dependence. Every drug has multiple effects: although a user might seek only one effect, drugs work at multiple sites in the brain and other organs. Amount matter: larger doses, more frequent doses, or faster onset of effect can produce different effects compared to small doses. Users history and expectations affect drug related effects: an experienced user may experience different effects compared to an inexperienced user, expectations may make a drug effect more or less likely to occur. Drugs are not good or bad: drugs are chemicals on a shelf that are inactive until they enter the body, blaming the substance ignores all the factors that may lead to abuse.
