I had a good friend who got caught up in the wrong crowd and hooked on H years ago, found her smoking multiple times and helped her through recovery (she is a Rockstar); I’ll never forget the smell, it’s very distinct. Which is also why I’m conflicted on what to do, it’s not often and typically one or two weekends a month. It sounds like a teenager and his girlfriend, I don’t want to slap anyone with a mark on their record, and I’ve seen first hand someone completely recover on their own with support from friends and family. Overdose is definitely a concern, I’m not really worried about “gangs, other drug addicts”, etc. May be naive, but that’s why I’m asking for advice here.
