Dont be so sure,some of the most technical people in the world are potheads.
Ive worked for several companies that do alot of stuff for the oil companies,
its amazing how much money,resources and man hours these companies waste trying to get contracts and such. they really need some kind of hydraulic valve or something put on there. theres a company I used to work for about 10 years ago that manufactures special pipe cutting equipment they could use to make the pipe useable again. Maybe one day mankind will learn that greed isnt the answer,and I hope that for my kids sake thats sooner than later. As if the current economy isnt bad enough now we gotta deal with all of this nonsense too. Maybe another revolution of somekind will wake them up.
