We're all pot heads deep insideU.S. and Brazilian researchers have just proven that one of Bob Dylan's most famous lines"everybody must get stoned" is correct. That's because they've discovered that the brain manufactures proteins that act like marijuana at specific receptors in the brain itself. This discovery, published online in The FASEB Journal (http://www.fasebj.org), may lead to new marijuana-like drugs for managing pain, stimulating appetite, and preventing marijuana........Go to the Psychology news blog (Added on 4/21/2009 5:28:13 AM)
