My boyfriend and I want&amp;need to detox from fentanyl. We have been smoking it daily for about a year, and was smoking black tar heroine for about 4 months before starting the fentanyl--so it has been 1.5 years of daily use, but always smoking, no IV use. We want so badly to quit, and have tried a few times, but the physical detox is so painful and hard to endure, so we have been successful every time.
