Document Summary
Smart drug improves cognition without any side effect. Taking a psychoactive substance for non-medical purpose, out of curiosity. A maladaptive pattern of drug use leading to clinically-significant impairment or distress, associated with difficulty in controlling drug-taking behavior, withdrawal, and tolerance. The state of needing a drug to function within normal limits. Withdrawal symptoms in the absence of the drug. Tolerance to its effects with repeated use. Temperance (control of supple, calls for abstinence) Addicts continue to use drugs in order to avoid withdrawal. Over time, drugs no longer have the same rewarding effects they merely allow the person to feel normal". Not all abused drugs generate withdrawal symptoms. Different drugs produce different withdrawal symptoms with different neural bases. Once dependent you should continue taking drug , but people spontaneously stop. Once drug-abstinent, users should not relapse sine motivation has disappeared, but they do. No explanation as to why people take drugs in the first place.
