At some point in my life I tried to hook with Mary Jane, but never felt anything. It was mild curiosity, also I was hoping it could help relax for my creative side (lol). Afortunately it didn't do anything for me and I could leave it alone without having anything bad happening to me. It was a coworker who introduced me... or tried to.
I don't care for weed. Much less any other type of drugs. I don't really think is worth it to entwine yourself with drugs. I don't mind people that are mature and can control their rations and priorities in life. I just don't see the point right now.
The friends that do weed or smoke their ciggies. I respect it and I'll never will lecture them. I am pretty sure I can't say anything they haven't heard before. So far people I know that uses it are responsible with it.
