Scary how accurate satire can be sometimes. Sad, too.
Cannabis smoking ‘permanently lowers IQ’ 8 points.

The average person—yeah, we’re all above average—starts out with 51% of people smarter than them.
After 20 years of 3 times a week weed use, there is an 8 point unrecoverable loss in IQ, so that, then, 71% of people are smarter than the pot-head.
But then, the upper-middle-class people who want the poor to have “medical” marijuana, tend not to use it themselves.
