How can a person stop doing drugs? Besides rehab. So many people around me are dying from overdosing even after rehab and such...

Deep... After birth only guaranteed thing is death......no matter what you do (Pope Paul, Elvis, Michael Jackson, Reagan). Now you society, environment, education, family, belief, hope, faith plays a role against your gene to change your speed at which you meet the final end point. Like the wild animals, wild diseases of the past...this is the new killer.
