Looks like me and you are in the same boat, FRiend. I'm a mechanical and nuclear engineer about to celebrate 10 years of regular smoking. 'Celebrate' because I love to rub the lazy doper stereotype in doubters' faces after I blow them away with my work.
Nobody even believes that I smoke until I show them the greens. Everyone thinks I'm joking because EVERYONE knows 'pot makes you stupid'. Even better is when someone tries to rat me out and nobody believes them :)
And yes, I also know other extremely successful and influential people that think nothing of lighting one up. Engineers, mathematicians, chemists and business owners just to name a few.
Glad to meetcha! Actually I don't do it anymore, but for real I know some of the best scientists, engineers, and CEO's who partake regularly. Most of them quite well off.
