It's good to own up to one's own hypocrisy, Man; I've had to do it numerous times myself. Ironically, though, a consistently sound, exegetical reading of the Bible leads to a denouncement of prohibition and of the drug war. It also leads to a rejection of statism in general (e.g., the tyrannical Roman empire was deemed a "beast" in the book of Revelation).
By original design (and not always description), civil governance is severely limited to issues of justice in a biblical worldview, and a high priority is placed on self-government. Though it may be sinful and self-destructive, drug abuse can in no way be considered a civil crime in Christianity. Sin doesn't automatically equal civil crime.
A sound reading of Scripture also leads one to believe that drug use is not inherently sinful. It can be, but not inherently. Individual Christians and churches might say otherwise--and they oftentimes do--but their sentiments aren't morally or exegetically justifiable. And given the doctrine of inspiration (i.e., that God breathed out the words of Scripture, as per 2 Tim. 3:16), Christians are supposed to care about exegesis.
Thanks for you insights @expatlove. I'm not longer a Christian so for me, the only "sin" is to use force other than in self defense. Peace and love to you and thanks for finding interest in my stories.
