Hey Barry I normally find your posts well researched and informative but I gotta question you on this one.  What evidence do you have of pot being "flavoured" with cocaine or meth?  I have never heard of that happening.  I also remember some reports that ecstasy was being laced with heroine.  I chatted with a RCMP friend who has spent time busting drug dealers as well as an emergency ward nurse (ICU) and a former and current pot dealer and all told me they have never seen such adulterations nor have they even ever heard of them.  If you have a report of such a finding I would be interested in seeing it.  Otherwise I will put it down to urban myths intended to scare people away from drugs.
