I use meth via IV, i've tried a small hit of H one time and just like with chasing that dragon, I didn't care for it. For anyone who hasn't taken their fix through a needle, don't do it, because once you develop the higher tolerance that comes with IDU, every other ROA seems wasteful and doesn't give you a fix anyways. I can't speak for anybody but me, but when you're really itching for dope and all your friends are getting high and you are not because there aren't any clean rigs, you seem to not care about the risks of sharing needles as much, of at all. I hope somebody reads this and can learn from my mistake and choose to refrain from IV altogether, because that one day when I didn't have a clean needle and decided to just sanitize it in bleach and rinse with water, it wasn't enough because I still contracted Hepatitis C.
