i was given a script for 2.5 marinol a couple months ago and they sit in the fridge short 4 to this day. it did nothing to help the muscle spasms and in fact only made for a general feeling of uneasiness for me and another friend with skeletal/muscular pain. they're also very expensive and most insurance companies do not cover them (mine covered all but 50-some bucks of the 280 normal cost for 30 tho)
