You'll notice I stuck to cigarettes....yes, "medical marijuana" is a different story.
I've heard unofficial reports that medical marijuana is effective as often as 25% of the time when other pain-killers aren't effective. Apparently the U.S. govt has been conducting an experiment for the last 25 years, to validate the conclusion that many have already learned - that it does have medical benefit. Hopefully our government will wise up and get past the "stigma".
