I don't know why this is something to be proud about? What good does smoking marijuana bring society? Does it help bring prosperity to Canada? Does it make us smarter, and help us study better?

Wheres all the studies from the 80's and 90's that proves marijuana destroys neurons, and causes permanent damage to memory, and other parts of the brain?

I guess when everyone kills a few million brain cells, it will take longer for individuals to perform complicated tasks. Why would people want to destroy their IQ, and make life harder, just to feel hip and trendy?
