Whatever happened to good ol Boones Farm and Marlboros?

I met a junior high teacher this week. She told me that the kids at her school are crushing up Mucinex (yes- the cough suppressant) and smoking it. I was assured that the kids are not able to get high from this, but it disturbed me. To me this goes beyond normal curiousity and experimentation. Makes me wonder what the kids are looking for that they aren't getting. Parents- talk to your kids!
