You say you have 0 tolerance, and you insist you won't turn to the needle. I can understand that, but a bigger question would seem to be "do you plan to not get addicted"? Because you obviously will if you do it enough on a regular basis. And you most certainly cannot have any idea if you will turn to the needle if you are not addicted. I will tell you right now, some people start just snorting H with no intention of IV, but they end up doing it.
Look at what you rational is for doing heroin instead of Rx narcotics, because it is "economically" the better idea. Well of course there is the rush, but I think the economical reasons (much higher BA) is the reason so many people switch to IV. You already skipped a step in a lot of people narcotic addiction timelines that is usually forwarded for economical reasons. Most start with oxys/opanas( snorted or eaten), then to H (snorted), then to H ( IV). But you are not even addicted yet, well maybe you are now. Nonetheless, its already been said, no one starts with the plans to get addicted. The fact is you are most certainly in the minority and bucking the odds if you continue to do what you are doing and don't end up addicted.
