I am wondering if there is a plateau for heroin tolerance. Lately, I've been doing a larger amount then normal (IVing) and I haven't been able to get a good rush. I figure its from a heightened tolerance but is it possible for my tolerance to plateau? I used to do about 100 mg per shot for a decent rush and 200mg would give me a really nice one. Now 200mg does almost nothing for me. I've thought about trying a 400mg shot, but I'm worried that it if I've plateaued then I'll just be wasting my money. I know with some opiates like suboxone, you can hit a plateau (not sure waht the plateau dose is) and you wont feel any greater affects once you reach it. Is this the same for heroin or can I just add to my dose to feel a nice rush again?
