Over 90% of the adult population uses alcohol. Nearly 50% of men will admit to having been drunk in the previous three months.

Amphetamines are the most common illegal stimulant.

When someone stops using heroin the main problem to overcome is not the physical, but the psychical craving for the drug.

Nearly 1 from 5 men and 1 from 10 women smoke 20 or more cigarettes a day.

Caffeine, alcohol, tobacco, pain relievers and tranquillizers are all potentially addictive drugs.

Marijuana is the most employed drug among young people.

The dealers of heroin often mix it with other substances - powdered sugar, dry milk, codeine, even pepper, brick, chalk, strychnine, soap-suds, glass wadding, which can produce poisoning, even death.
