I heard about this a couple of years ago when my husband and I were attending a Commander's Course for the Air Force. I agree that a person looking for a thrill will find it at any cost....but the big issue that hit us at the time was that it couldn't be detected on routine drug tests. I don't know if that has changed. We have always grown salvia in our flower beds -- now do I have to worry about junkies digging up my garden?
