I am guessing the demographics of marijuana users would shock you.
You really should think about leaving the 1950's, and your out-of-date concepts of cannabis usage, and joining the 21st century.
Yes, exactly. I happen to know a Dr. who imbibes regularly. My friend who is an architect does as well, in addition to several other professionals I know. I can think of at least 4 people close to me with graduate degrees who use regularly. These are very successful, productive people. The stereotype of the "lazy, hippie, dopers" is tired and inaccurate in our current society.
Side note- I went to a concert at Red Rocks last month where nearly everyone was high. Guess how many fights or aggressive incidents occurred? Zero. Everyone was polite and chill. I had several friendly encounters with people I'd never met. Go to any outdoor concert at Stir Cove in Council Bluffs where booze is flowing and it is a much different atmosphere.
