Some people think using drugs is fun, but they can bring more than their fair share of problems. 

Some people can get addicted while others have bad reactions - so bad that some have died. Drugs can also trigger mental health problems like psychosis, anxiety or depression.

There's no way of knowing who will be affected like this or when - especially when nobody's really sure what they're getting.

And of course, if you get caught with drugs, you risk getting a criminal record, a fine or going to prison.

Given the trouble drugs can cause - for relationships, your health, with the law, work, study and money - it pays to know the facts.

That way, you can make your own mind up and help others around you make better choices.
