i had the same ordeal with my son tobias yvsa, he started on mariuguana,then lsd,then speed ,injecting ect. it was terrible i pleaded with him to stop but all was to no avail,he went to crime to support his habit,and was a real mess,it broke my heart to watch him go through this,the last time he went to jail was for 3mths,he got a break from the regular supply of drugs and this helped him kick his habit,it has been a long struggle but finaly he is back to normal again , he is now 23 and been of the drugs for around 18months, i dreaded that one day he would be found overdosed, but thank god it didant happen and things are now fine. I HOPE AND WISH THINGS GO THE SAME WAY FOR YOU AND YOUR FAMILY MATE. it is a anguishing thing to watch a loved one go through this but hope it turns around for you. best wishes cave troll.
