There's really only one reason anybody does drugs or alcohol: Psychic Pain. All of are born with a trace of it but those of us luck enough to have an upbringing which keeps us in touch with our feelings and socialized to even a minimum of rational interpersonal problem solving ability are basically immune to such karma leakage. Wish it had been me.
Speaking of self-discovery what disturbs me is knowing I'm related to these psychos through the Walker side of the family tree.
