I've been smoking cigarettes for almost 20 years, the same amount of time for hash, and later weed. Was diagnosed with mild relapsing/remitting MS in '06, but haven't quit as it's about the only vice I have left. I've never felt any changes from smoking either cigarettes or weed, but the amount of chemicals added to tobacco cannot be good.
I've done really well since diagnosis, a few dips her and there, but mainly okay. I tried quitting smokes maybe three years ago and had some nasty relapse sensations...so I started smoking again. Weed works differently for everyone, but I find it useful and had actually asked my doctor and neurologist if I should quit pot, to which they both said 'Only if you want to'...not the response I had expected at all! I don't use any pharmaceuticals, so it really pisses the doctors off.
Stress has been my biggest trigger in the past, but I regulate that now and stay away from things that annoy me as that's the stress I can't deal with.
Fee002: did the limb strength issue come up for you with cigarettes or alternative smokable's?
