I am not a heavy drug user by any means. I was a firefighter for over 20 years and never did any drugs except alcohol occasinally. I tried pot when I was in High school, but that was it. I do not have an addictive personality, but am adventurous. I have a friend who introduced me to Cocaine... I was always curious, hearing all the stories throughtout the years as it being so euphoric.for me it was rather disappointing, it was ok, but I guess I expected more of a euphoria. So I'm curious in trying a speedball, but don't know the amounts to mix. If I buy an eightball of Coke how much White heroin can I mix without going overboard? I am totally unfamilar with heroin. Oh, and I intend to snort it!
