Can I be prescribed marinol if im a minor (under 18) in florida?

Doubtful. Unless you have a legitimate medical condition, it would be unlikely that you could get a prescription for marinol. This, of course, is if you go to an ethical doctor. Unfortunately, there are too many doctors (many seem to be located in florida) that will prescribe any medication for anyone as long as they are willing to pay. The good news is that the dea is closing these practices down!
