One of the most surprising findings in this report for me was:

"There is moderate evidence of no statistical association between cannabis use and: • Incidence of lung cancer (cannabis smoking)"

I thought it was pretty well established that inhaling any burning plant matter increased the chance of lung cancer. But I guess not.

Not surprising was:

"There is moderate evidence of a statistical association between cannabis use and: • The impairment in the cognitive domains of learning, memory, and attention (acute cannabis use)"

and most worrisome was:

"There is substantial evidence of a statistical association between cannabis use and: • The development of schizophrenia or other psychoses, with the highest risk among the most frequent users"
