About Cannabis

What happens if you use cannabis often?

Cannabis can be an addictive substance, and regular use can result in long-term problems for your body and brain. The impacts of cannabis can be more severe if you start using regularly during adolescence or if you have a family history of mental conditions such as schizophrenia.

Regular use of cannabis can have impacts on your memory, attention span and ability to learn new things. There is lots of different research on this topic. Some suggests that these effects will reduce once cannabis use has stopped for several months, and others suggest that long-term use can change brain structures and create lasting problems.

Regular cannabis use has also been linked to mental health disorders. It is believed that cannabis can increase your chances of developing psychosis or schizophrenia if you have a family history of this (sometimes called a genetic predisposition). Research has also shown that regular cannabis use in adolescence can be linked to depression later in life. Cannabis – in particular, CBD – also has positive effects on the brain. CBD is used as a treatment for anxiety and sleep disorders.

Like tobacco, smoking cannabis regularly for a long period of time can have unpleasant effects on your body. When smoked, heavy cannabis use can be linked to chronic lung issues and cancer, especially of the lungs, neck and mouth area.
