OK, the scientists have to put in their little disclaimers so they can continue to get their funding. It's part of the "dance" they have to do to survive in the scientific world. The government still has a hand on the science world. As for pot and grades, well this study kind of puts the lie to their claims http://www.cmaj.ca/cgi/content/abstract/166/7/887 (ever think of saving these little gems that I post? I have a note book of over 200 of them now- makes a great "show and tell" among friends) I also graduated with honors and was the oldest member at the college's "stoner's table" in the cafeteria. (I was an "honored member" of the table after I showed them that a little old lady like me can still handle a 4 foot bong at a Friday night party ) I was stoned most of the time while in college and still am! I work in education ( be nice to that always smiling teacher's aide- it might be me! LOL) and am a California legal MMJ User.
