I actually have a question can anyone please help. Ok so I have been doing dope for months now yeah I'm hooked well this morning had no dope and had work. I'm a roofer so doing that sick yeah right. Well I took 8mg Suboxone and it helped but now I wanna know how long do I have to wait until I can do heroin without it being blocked? I only took 8 mg Suboxone for one day at. Like 10am this morning it's now 11pm so it's been around 13 hours
