Many people using cannabis think of themselves as recreational users. Their claim is that they only use it to relax, alone, or when they are together with friends. And many of them would have no problem at all, and it is just as they say. But Cannabis Use Disorder can become very real. When a person thinks that they cannot get through the day without using cannabis, it becomes a problem. In fact, it was introduced by the Diagnostic and Statistical Manual of Mental Disorders as a proper diagnosis when there is a problematic use by a person.
