I read in GW literature ages ago that 'Sativex is to Marijuana what filter coffee is to the coffee bean' or something like that..
I tried smoking grass to help MS a few years back. I didn't like it much when I was a teenager and I definitely didn't like it a few years ago. I got really stoned with a makeshift pipe from a soft drinks can with holes punctured into the top and got really stoned every night. I kept it up for a month and I couldn't go on. I hate the confusion, and I hate wanting to do things but not being able to get things done! Besides, I realised that it tended to make my heart race. And, in my case, it didn't seem to help my MS. I don't actually suffer from pain but I heard that it was supposed to help with muscle stiffness.
VillageMaid- do you take it in doses which actually get you stoned?
PS - I remember reading a study that it offers, in the long term, a measure of protection for nerve cells. I don't remember any details mind you. Perhaps it was something along these lines , but I thought it was something other that cannabinoids being an anti-oxidant http://norml.org/index.cfm?Group_ID=3853
