LSD stands for its chemical name, lysergic acid diethylamide, and is commonly called ‘acid’.

It’s a powerful hallucinogenic drug – this means that users are likely to experience a distorted view of objects and reality, including seeing and sometimes hearing things that aren’t there (these are hallucinations). The experience of taking LSD is known as a ‘trip’. 

Time and movement can appear to speed up and slow down. Colour, sound and objects can get distorted and you can experience double vision.

These distortions of your senses can be quite unpredictable, sometimes pleasant, but sometimes very frightening (these are called ‘bad trips’).

Risks

LSD is a class A drug, so it’s illegal to have for yourself, give away or sell. Possession is illegal and can get you up to seven years in jail and/or an unlimited fine.

Supplying someone else, even your friends, can get you up to life imprisonment and/or an unlimited fine.

If the Police catch you with LSD, they’ll always take some action. This could include a formal caution, arrest and prosecution.

A conviction for a drug-related offence could have a pretty serious impact. It can stop you visiting certain countries – for example the United States – and limit the types of jobs you can apply for.
