After more than 30 years of daily cannabis use with occasional tolerance breaks I recently took an IQ test along with a series of mental evaluations and was in the 99th percentile. So maybe cannabis took me down just enough to avoid being one of those Mensa jerks?

It might be interesting and revealing to see the correlation between casual cannabis dismissal and low or reduced IQ, but of course that goes against the popular narrative and looking for potential errors isn't where most scientists focus since that isn't super glamorous or likely to get citations from publication.
