I have a few questions about the insuffulation of speed balls (heroin+cocaine) and pharmaceutical psuedo-speed balls (painkillers + stimulants). What are the dangers of insuffulating speed balls as compared to the dangers of insuffulating heroin by itself or cocaine by itself. What about a psuedo-speed ball with oxycodone instead of heroin? What about a pharmaceutical stimulant (adderall or ritalin) instead of cocaine? What about a purely pharmaceutical psuedo-speed ball with oxycodone and either adderall or ritalin?
Basically I'm looking for an overview of these combinations of drugs with their pros and cons, as well as their comparative dangers if that makes sense.
