well here in uk there is always big debates regarding the legalisation and medical uses of cannabis, a few years ago the govt de-classifies it so that you could not get prosicuted for posession but it could be confiscated (they then re-classified it again 1 year later), however that was in regard to cannabis resin, as for cannabis plant (green it is called over here) posession will lead to prosicution, and cultivating or supplying will lead to a jail sentence, the use of cannabis in a social basis is ok if it is done correctly and in moderation, i smoked it myself for 15 years (i havent smoked it now for 4 years) but i can understand how some people can come mentally dependant on it, i know of people who dont want to work and spend their state benifits (what come from us tax payers) on cannabis, as for medicinal use i can only reflect on my own experiances, approx 10 years ago i dameged my back working in a chemical factory, i was physically disabled for 18 months ( could not sit down for 12 months) now the doctors where giving me allsorts of pain killers, which didnt fully work so i tried increasing my intake of cannabis to see if it helped ellieviate the pain, and i was smoking between 2 - 4 ounces per week and it didnt have the slightest effect on the pain whatsoever, so it didnt help me medically ! so pleased now i dont smoke it anymore as i feel more fullfilled in my life, happier and more confident.
