| drug dependence | Use of a drug for a reason other than which it was intended or in a manner or in quantities other than directed. Drug dependence is a compulsion to take a drug to produce a desired effect or prevent unpleasant effects when the drug is withheld. Risk factors for drug abuse include: low self esteem, inability to deal with stress and emotional instability. Juveniles use drugs due to peer pressure. Signs of drug use in children include: a change in friends or group, long absences from home, poor performance in school, seclusion, stealing, lying, criminal behaviour, deteriorating family relationships, signs of drug intoxication and changes in behaviour.

Many labs now offer quick and inexpensive urine drug screening. Psychological counseling and parental support will be necessary in children with this problem. (27 Sep 1997) |
| drug design | The molecular designing of drugs for specific purposes (such as DNA-binding, enzyme inhibition, anti-cancer efficacy, etc.) based on knowledge of molecular properties such as activity of functional groups, molecular geometry, and electronic structure, and also on information cataloged on analogous molecules. Drug design is generally computer-assisted molecular modeling and does not include pharmacokinetics, dosage analysis, or drug administration analysis. (12 Dec 1998) |
