Most pharmaceutical opiates are a waste smoking. I know some will argue that fact, but your just wasting a ton. With oxycodone, orally you are getting in the 90 percentile and iv its is100 pecent. if you smoke it, its less than 50 percent.. nasally it isn't much better. The only opiates that I have heard are worth smoking is fentanyl and H.. Other than that, its a waste. Unless there is an opiate that works well smoking and i havent heard much about it. I dont know about morphine, but i think the heat kills it before it vaporizes or it comes close.... Just say no to smoking pills...
