Four to six hours, but the initial rush from injection lasts only 20 minutes or so (before it becomes more of a sedated high).
Anything between 30 mins - 10 hours, and stays in your blood system for 30 hours.
Typically around 2-4 hours.
They will return to normal size not long after the high is over. How long the high lasts depends on how it's administered.
you snort it and if you get high then its heroin
If the heroin is being smoked "chasing the dragon" then contact high is possible, otherwise... No!
Yes, even a small dose will block the high you normally get from heroin. Adding heroin to Suboxone can have a dangerous additive effect. Many people have died from trying to get high while on a replacement drug.
Over the long term heroin will degrade. The lower the temperature the slower the decomposition of the heroin. Certainly room temperature is fine. A high temp (120+F) would be bad. Storing it in a fridge would be best if its going to be many months or years. Keeping the heroin dry is as or more important than the temperature.
