If a celebrity (read slave) is acting out, they feed them drugs to keep them zombified and compliant. Kanye was threatened with this due to his recent behavior. I'm sure the psychedelics are also used for control, as those chemicals can open someone up to all sorts of influence.

In fact, I could imagine psychedelics are used often in Satanic mind control processes. Abuse someone until they are weak and susceptible to control, then make them trip balls, and in their weakness and fear, they will kneel to whatever comes knocking on their soul.
