I smoked cannabis all through my University years...

My roommate didn't smoke (wrestler)...and was a stellar student.

The first time I came in all stoned and sat down to study...he was like...not going to work.

Oh yes it will...next morning before class...I'd smoke some cannabis before the test...no problems ever.

He could not believe my grades and my study habits...but I stayed in the same frame of mind for the intake and the outtake of information.

That and attitude has a lot to with...everything.
