The consequences of abusing drugs may be intoxication, abuse,
withdrawal, and dependence. The different consequences are indicated
by different symptoms. Intoxication tends to be an immediate
consequence of drug use, and the drug is considered abused when its
use begins to interfere with other aspects of the user's life.
Withdrawal symptoms may occur after a single intense episode of drug
use, but become more likely after repeated, chronic use. Finally,
drug dependence occurs when an individual continues to use the drug
despite significant, usually obvious, adverse effects of drug use.
We can't cover all drugs or even all types; there are too many.
However, the consequences of addiction to the different members of a
single class of drug are likely to be similar. For example,
addiction to a stimulant like amphetamine is likely to result in
behavior and consequences for health similar to that caused by the
abuse of other stimulants, including cocaine. The same is true of
depressants or hallucinogenic drugs; so if the drug or drug class
that you're interested in isn't on the list, choose a drug that is
related and start your research there. We will give you links to
sites with fuller treatments of specific drugs.
There are also disorders that result, not from addiction, but
from toxins or the side effects of medication. You will find some of
these toxins on the list following the list of the most common
