Huh? Not in my experience. Smoking it you end up wasting a ton of it. And snorting is only reserved for number 4 heroin (powder/chiva/China white), & even divested best jewelry of heroin users in my experience eventually you rather quickly switched to injecting it is a way to get more "bang for their buck".... and many as in my case shoot out all of their veins, especially with black tar, and end up shooting it intramuscularly which I did for the final six months.
Well I guess it's different from country to country... here in Germany I'd say more than 50% smoke it... and we mostly get #3 here and I can assure you that it is possible to snort it although not as efficient as snorting #4 since it is not water soluble by itself but since the nasal mucosa is slightly acidic it will still work... tried it myself plenty of times. However I suppose snorting tar is pretty hard to do but there is no place in Germany where you could get BTH.
As for the high... first of all you have to make a difference between the rush from IV'ing and the general high from H (or most other opioids)... the rush when IV'ing smack is a great feeling that will last for maybe 10-20 seconds, comparable to an orgasm at least for me. The general high is fun for the first few months but after some time you won't feel it that much, you will just feel normal when high and feel like shit when not... and if you do a lot you will get very tired. At first though it is a great high, by far my favorite.. clear mind but very euphoric, allround well-being feeling. Cocaine is so bad in comparison to that that you can't really compare the two...
Dilaudid/hydromorphone IV is the greatest feeling on earth pretty much...
But for me it wasn't really the high or the rush that got me hooked - no matter how good you feel when high it is nothing against how bad you will feel when coming off.
