I toked all 5 years of college, I majored in psychology so those classes were interesting as hell, being stoned in class actually made me retain all the info because I was so concentrated to what the proffesor was saying. I also toked as a Field Rep for a healthcare company, not a good Idea because I had to drive all day and schedule appointments. In my own opinion I think that waiting until you get off work makes that first toke of the day that much more exciting.
