Craige [McMillan] mentions drugs as one of the causes people use to explain evil. I would just like to mention that drugs are intimately tied to demonic influence and/or possession. We are told in scripture to avoid sorcery and witchcraft. The word in the Greek is pharmakia, obviously the source of our word pharmacy. The use of drugs was clearly tied to the practice of sorcery and witchcraft. What do drugs do? They lower ones resistance to demonic influence. The mind expanding properties of drugs are provided by the Evil One. He uses them to bring you progressively closer and closer to him. So Craige is right that the problem is evil, but do not fail to consider the impact that drugs have in moving people into the sphere of evil. Shabbat Shalom
