Social, cultural and psychological factors combine to determine how the drinker then behaves. Euphoric, amorous, weepy or aggressive behaviour may be exhibited, as alcohol lessens the learned restraints. Drinkers can die from fatal overdoses of alcohol through depression of breathing. Disease and failure of these body organs and systems can lead to death. The effects of cannabis are even more variable than most other psychoactive drugs.
Cannabis is a unique drug.
It defies attempts at precise pharmacological classification since its effects are so various. Under different conditions it can act as a stimulant, as a sedative, as an analgesic or as a mildly hallucinogenic drug. It has superficial similarities with many other drugs, but on the whole, the differences between cannabis and other drugs are more striking than the similarities. In its chemical composition cannabis is an exceedingly complex substance. Short term effects Effects last 2-4 hours.
