He is no Christian if he is on drugs. Simple really. Live it, not lie it. Looks like a drugger to me. One cannot serve God and mammon.
He may well be Conservative but he does not follow the Nazarene.
I am Christian. Take lots of drugs. Prescription ones as well as caffeine, ephedra (Allegra D), alcohol, even occasionally nicotine.
Just because something is allowed by law or recommended by a Dr means nothing in Gods eyes.
Perfectly legal to get an abortion, play the lotto or gamble, doesnt make it right.
If you believe God wants no drugs in your body it would mean legal or not. Just sayin.
