"In my opinion, recreational marijuana use by adults in the workforce is in many ways a harmless and victimless activity."

Perhaps, except for "short term memory loss" associated with smoking cannabis.

I would think short term memory loss (persistent as the drug remains in the body for some days/weeks) could be an issue if you are a surgeon, airline pilot, stock broker, etc. where decisions must be quick, clear, and accurate.

No, only its inert metabolites remain in the body.

could be an issue if you are a surgeon, airline pilot, stock broker, etc. where decisions must be quick, clear, and accurate.

Alcohol hangovers could be an issue for those people, too. What's your point?
