If you've ever spoken with someone who was a serious drug addict, they can tell you of the demonic experiences they had while high on drugs. I have talked with such people who claim that they saw demons and unbelievable nightmares. Drugs and alcohol are gateways into the demonic spirit world. Those who engage in substance abuse are inviting demons to infiltrate and control their mind. Often, drug abuse is intentionally used in witchcraft to make contact with demons.
