About Dean using drugs, maybe it was a plot cut short. Maybe they were just making a point that hunters get hurt and feel pain even after the visible cuts heal. They wouldn't have a regular health care plan, and wouldn't want to be tracked by pharmacy records. Maybe it was from allies that provide hunters with health care assistance,  I think maybe they decided to go with Dean drinking more when he struggled to cope. For his true addiction, that seems to have turned out to be killing.
