because marijuana has the amount of THC in it to make you high. I don't even think cigarettes have THC in them. infact im sure.
Well if weed is legalized, everyone will be walking/driving/working when they are high......so better off when its not legal.
Actually im pretty sure it does have THC in cigs, I remember our health teracher telling us, hell hte book even said so
I highly doubt there is any tetrahydrocannabinol-9 (THC) in cigarettes. Look at the name, cannabinol reefers to marijuana. Also, the tobacco industry pays too much to the government to make cigs illegal. They also take measures to prevent marijuana from being legalized which would cause more competition for them.
