To answer the quetion, when people say stuff like this I laugh.. Oxycodone and Diacetylmorphine are opiate of almost the exact same potency and strength. .The only difference(aside from structure) is in the subtle overtones of the high, and the sources.
Yes, oxycontin is pharmacutical grade... Heroin is not.. But pharmacutical grade only counts when injecting, smoking or snorting it really makes no difference. Since oxycontin is time release, it is actually less afe to inject than H..
Aside from that Heroin should be superior. First a $20 sack of decent H should be the equivalent of an OC40, which runs $30-40. So heroin is cheaper.. Also, in most people's opinion, H lasts a couple hours longer than the oxy high..
So you have a cheaper, longer lasting, equally as potent opiate that is unfavored by some because of the stigma that society has placed on it.. The only reason I could see someone choosing oxy over H is for a social situation. OXy tends to be the most lucid and least sedating of opiates, making it much more of a social drug than the downer, heroin..
