Before you reply, let me clarify: It's pretty damn obvious that marijuana "slows" you down. The methods of how weed slows you down I counter. What if we changed the method of consumption to a brownie? Would blood vessels restrict in the same way? Smoking increases your blood pressure by restriction of blood cells. I've read that a fatty lipids develop surfacing the brain, slowing down communication from the brain to nerves.

Sorry mate, I should've mentioned this the first time.
