I myself have never done Herion, but my sister and brother in law were both very BAD herion addicts. They would shoot up at least 4 times per day. Luckily, they are both off the Herion and both did it different ways. One is on Methadone and the other went CT through rehabs. I do know that my brother in law did have Naltrexone (pellet) in his arm and he found ways around it to get high and it actually made the pellet melt very very quickly. Anyway, the reason they are both off is b/c they Really wanted to be off! They both had gone through every Detox/Med there was until they finally ended up clean..It took many many times for that to happen though!!! Best of Luck though to you and your BF! Opiates are a hard thing to get off of!!!
