Im a reformed heroin addicted and have been cleannow for 5 years but when i came back to Ontario from British Columbia i couldnt find any heroin here except about 3 hours away so i would break down the oxys (80mg) in the water in a spoon and heat it up and would use a half a gram of coke and the use a filter to suck it up in the needle and when i would bang it , it felt almost like a speedball!! I use to do speedballs all the time in BC. I use to also mix in a bit of crystal meth with the heroin and coke and i called them deathballs as your putting urself in risk of having an overdose if you do to much!!! I love my weed now as thats all i do now!!! An ounce a week of bud is my new habit!!!
