Drug use can affect your  physical and mental health, your family life, relationships and your work or study. Using illegal drugs can also get you into trouble with the law or cause money problems.

Drugs can be broadly divided into three categories based on their main effects. They may act solely as stimulants (which make you feel alert and like you have lots of energy and confidence as depressants (make you feel relaxed and chilled out) or as hallucinogens (make you view reality in a distorted way). Quite a few drugs have mixed effects.

All drugs carry risks and you never know how you’ll react to a drug.
