I am a Christian and agree with the above statements. I also use a certain green plant which is on the face of this earth for a reason instead of using a man made synthetic DRUG as prescribed by a doctor to relieve pain. It is as if the bible is interpreted differently every 10 years to coincide with political changes or just to make a point sound valid to church members regardless of the situation. You have a very valid point and I am sure if you asked 10 Christian's you would receive 10 different answers dependent upon their pastors view and not personal interpretation.
You beat me to posting this but was unaware of the response to religion on this server. GREAT TOPIC!
Edit:
You don't think their response will be tobacco is the "tree of knowledge" do you? The only thing I have learned from tobacco is...I like it
