I believe that smoking pot makes you stupid.
--while long-term cigarette smoking is bad for your lungs, there are not millions of people whose observations led them to believe that tobacco lowers your IQ and makes you slow and stupid.
Nicotine actually seems to enhance reaction time.
Why the distinction?
These millions of people believe this not because they've read the scientific studies showing lower IQ,
mental health, learning, & memory impairments from using pot,
but because they've seen the results first hand.
Studies conflict, of course,
but extensive research shows what
millions have directly perceived,
that long-term routine pot use leads to serious mental health issues.

It may be that those using pot say " I don't think I am impaired"-
But if the assessment is based on addled thoughts, they may cite cherry picked reports from NON neurology highfaluting magazines because the level of writing of science journal is beyond diminished capacity.
