Sometimes their brains become messed up on drugs.
I've never used illegal drugs, but I had a two-drug combination treatment for lymphoma, and after a month or so I had some strange mental side effects, weird dreams and severe depression when I woke up.
So I imagine other drugs can mess up peoples' heads.
