Oh damn.

Cannabis/THC doesnt not kill brain cells. It's a commen mis-conception, and only proves that the persons arguing it are uneducated buffoons trying to look big and important, when infact, they suck their thumbs at night.

Delta-9-Tetrahydrocannabinol kills one cell within the brain, called the Glioma cell. This cell is the only cell in the brain to cause cancer, and is infact not used by the brain for anything. By smoking cannabis, you are infact protecting yourselves from getting a brain tumour. For this reason alone cannabis needs to be legalised, not to mention the 1339459486846 other reasons that it should.

Over and in.
