Bad news from Scientific American: We all produce marijuana-like chemicals in our brains. Therefore, all of us need to turn ourselves in and spend time in prison.
[Marijuana] is also something everyone is familiar with, whether they know it or not. Everyone grows a form of the drug, regardless of their political leanings or recreational proclivities. That is because the brain makes its own marijuana, natural compounds called endocannabinoids (after the plant’s formal name, Cannabis sativa).
For some serious criticism of the alleged “war on drugs,” see this recent post.
