Hello sister, just wanted to add my welcome.
I am not a mom of addict, my boyfriend is a heroin addict and started this probably when he was 18/20 yo, it "progressed" and he went few years ago on shooting heroin mixed with sleeping pills cos heroin alone was no longer enough, yukkk (he is now 33). Since then he's been in/out rehab and had some months/year clean. Unfortunately he relapsed 6 months but now is in rehab again.
Recovery is a long bumpy road but does happen so keep faith.
take care
Carine
