Active heroin addiction, how long B4 fix needed?

The question is:

How long could you go without a fix in active heroin addiction?
Not an addict but will fill it in for my partner....probably 12 hours before he gets grumpy and needs it but longest he can go cold turkey is 48 hours maximum.

Good Poll...Heavenbound..when i was an active addict after the 12hr.mark depending on how much i had put up my veins..would be the max.and 18hrs.i would start to get minor withdrawls..any time after that it was real bad.So at a push 12/18hrs.
Take care......Davey
Any others, I'd love to hear more.

Thanks to those who responded already.

I figured that, & that is most likely why my daughter wouldn't come to visit me (she's 4 hours away & would most likely have had to spend the night so she wouldn't get her fix in time.) Sad.
Good poll is right, HB.

16 hours was my jump outta your skin witching hour........if my eyes teared up then I was a nut case knowing it was in the mail........ya know it's coming.

That'd mark the time to up and move.......as long as ya already had your loot...otherwise ya spent all day running round looking for money.

I was one of those "Morning Bag" people.....Tres could tell ya......I no matter had to have my dose to start the day......it'd call me all night.....but somehow I always managed to keep even a little bit......had to have it.
