Cannabis use can become an all-consuming compulsion. It's a psychoactive substance that while medically beneficial, and generally safe, can be abused. I should know. It's hard to drive by the dispensary without stopping. If I have a cone of Blue Dream, it will likely be smoked in it's entirety in one night while chasing a high. And sometimes that means augmenting things by drinking, so there's that danger as well. The compulsion can feel similar to drinking, cocaine and gambling.
