Potent opiate narcotic with a narrow therapeutic index (i.e., difference between an effective dose and a lethal dose is small). Side effects include narcosis, respiratory depression.
Heroin is not a suitable substitute for morphine.

Extremely addictive highly illegal easily obtained but expensive drug.

The main reason why most crimes are committed.

Slow, joyeus, inevitable suicide in a syringe..
Rob slowly sold all his possessions, witheld his rent, got into petty thievery, sold his arse on the street, murdered that old lady, got a lenient sentence due to 'diminished responsibility' and eventually died of an overdose on release from prison, oh the joys of Heroin.
