about three hours or maybe les depending on the person .....uhmmm acting wird and always wanting to relax also small eyes
- wanted to add my own answer--
- depending on how much you use, your tolerance, your weight, and how often you use, it can last anywhere from 2 to 8 hours... i'd say an average of 2 to 4, with the initial rush lasting a couple of minutes, and then a feeling of warmth and tiredness lasting for a while longer.
- and to add to the person who said "acting wird and always wanting to relax also small eyes," i think this person was talking about the signs of use, as opposed to the stages. and if I'm guessing right, they meant to say constricted pupils, not small eyes.
That would mostly depend on the height and weight of the user and the amount of heroin used. Also, it would depend on the person's tolerance and if they are a first-time user or a habitual user. I just did a quick search online and it looks like the effects can last anywhere from 2 to 8 hours.
Personally, I find that a heroin high - all symptoms included - lasted about 6 or 7 hours when I first started using. As I gradually got addicted I would have to shoot up every 2 to 4 hours just to avoid withdrawal, but I was extremely dependent on the drug at that point (which not all users are).
The stages will vary for different users. Mine went like so: first was nausea, but that only lasted about 5 or 10 seconds until I got the "rush" or "hit". The "rush" is a period of about 10 to 20 minutes (varying with the strength of the user's addiction) when you feel what people often class as "high" - a sensation of well-being or happiness accompanied by your body going a bit jelly-like. Your skin heats up and you feel warm inside out and you fidget a lot because you get "butterflies" and can't keep still. After these initial effects, the mouth starts to dry and usually the lips chap a little - the jelly feeling turns into heaviness, especially in your head, hands, and legs (or just from the waist down). Sometimes your arm starts burning (if you've injected), or your skin itches. For first-time and irregular users the nausea can come back, making you vomit and get quite dizzy, occasionally fainting. This second stage lasts about half an hour to 2 hours.
These next symptoms can overlap with the second stage - the existence of a clear third stage is debatable. Users begin to alternate between severe drowsiness and alertness, continue to be shifty and restless, and then your breathing starts to slow. It's sometimes really difficult to breathe. When that happens your heartbeat is also quite soft, maybe irregular, and if it is a case of an overdose then it's possible to slip into a coma at this point and medical attention is necessary.
Common visible signs of being "high" are the constricted pupils, dark circles around the eyes, pale skin and chapped lips. The rest is down to how the user used.
If the drug was injected, there will be track marks at the injection site and depending on the user there might be swelling, redness, raised/blackened veins. If it was snorted they might sniff, sneeze, cough and blow their nose a lot.
Take my advice - the rush isn't worth the rest of it. Never use heroin.
Just a side note to my answer: Heroin often causes insomnia. After I used I always felt tired, but could never sleep. My girlfriend found me high a few times before she helped me get clean, and she said I looked like I was asleep half of the time - I tossed and turned and didn't respond to her voice or touch. But I was awake the whole time.
I would say the high is very intense after shooting and stays intense to a lesser extent for the next two hours, then begins to taper over the next two to four hours. Much of this depends upon tolerance, dose and other variables. It is, oddly enough, difficult to sleep under the influence. Much nodding, etc, but sleep disturbance for sure.
^^added to above answer^^
Ya know, in rehab they were saying how you don't sleep when on drugs, you just pass out, which is apparently different, but anyways they were saying that for that reason you don't dream, but for me (im also a heroin addict) i have the CRAZIEST dreams/nightmares, and its very rare that i cant sleep, only if the heroin is VERY high quality, such as some good raw.
