The most common signs of cannabis abuse in young people are:
Skipping school or college
Red eyes, tiredness or other changes in appearance
Falling behind with homework or studies
Losing interest in hobbies and activities
Changes in mood or behaviour, such as becoming withdrawn, aggressive or anxious

If you are worried that your son or daughter may be abusing cannabis, the best thing to do is talk to them about it. It is never too early to intervene and the sooner you address the issues, the sooner they can get help if they need it.
