(a) Three drugs that can be abused

1. Indian hemp (marijuana/cannabis) - smoked to produce a false sense of excitement.
2. Cocaine - a powerful stimulant that is sniffed or injected.
3. Heroin - a highly addictive narcotic. (Others: tramadol, codeine, amphetamines, alcohol and tobacco when misused.)

(b) Six visible behaviours of drug addicts

1. Sudden mood swings, restlessness or violent, aggressive behaviour.
2. Bloodshot or dilated eyes and a generally dull, drowsy look.
3. Loss of appetite leading to sudden weight loss and an unkempt appearance.
4. Withdrawal from family and friends and keeping bad company.
5. Poor concentration, forgetfulness and decline in school or work performance.
6. Slurred speech, staggering movement and trembling of the hands.

(c) Two social consequences of drug abuse

1. Increase in crime and insecurity - addicts often commit robbery, rape and violence to feed the habit, disturbing public peace.
2. Breakdown of family and society - drug abuse causes broken homes, loss of productive youths and a strained public health system.
