I read that if you inject it, you will feel a rush of euphoria and a flush of the skin. Are those the same effects if you smoke it? Can you smoke it with pot? How long does it take to become addicted? How long do withdrawls last? I found stuff on the internet, but it would be helpful if people could personally tell me. It's hard to make sense of what's fact and what's nonsense. Which sort of makes me believe one of the main reasons we have drug problems is people are mixing fiction and opinion with fact.
