You can't trust an addict. Once an addict, always a scumbag. Addicts are irresponsible. Addicts are lazy. Addicts lack discipline.
Addicts break the law because they are bad.
Addiction is no excuse for illegal behavior associated with obtaining drugs. Addicts don't care about their families, their jobs or anything else but getting off. There are hidden emotional reasons behind addict's behavior that are accessible and treatable. Psychotherapy can treat addictions. Uncovering repressed fantasies, desires, hatreds, and dreams removes addictions.
