Addiction doesn't just affect the abuser, but family, friends, and loved ones as well. My brother (22) started smoking marajuana when he was 12 and that led to other illegal drugs and substances. It has affected me (18) in ways that I had never realized. I have had issues with anger and relationships throughout my life. I am now just starting to realize that the struggle of dealing with my brothers addictions has affected my entire life. I am now just starting to seek therapy for this through support groups and talk therapy. How has it affected you?
