Amazing. What is your evidence for that other than some anecdote? And do you believe drug use is more prevalent among blue collar workers than it is among white collar workers?
Finally, as I recall, you are a professor. What do you think the rate of drug use would be among college professors if they had to take routine drug tests before lecturing to students? Do you think the rate would be higher or lower than among blue collar workers?
Honestly, at the university level, the people I know, very low drug use. Would be easier to explain their ideology if their drug use was higher.
