my oldest son had a bout with heroin, begin when he was going to college and lasted about 3 years. Believe me when I say that stuff is poison and will destroy the person. Lucky for us we got him treatment as he wanted not to be using. It took 3 rehab bouts and a lot of prayers, he has been clean for about 3 years. Don't think its only bad folks that use drugs and get hooked, good people do it all the time. I will say this that without some support from family, friends and God they will be lost, not easy to break the addition and it is not as simple as just don't do it. Mush more complicated.
