"Of the many psychoactive drugs, licit and illicit, that are available and used by people who subsequently drive, marijuana may well be among the least harmful."

"may" does not convey certainty.

"least harmful" does not support your premis that pot does not impair driving.

You have picked up an opinion that is not based on fact, prolly from someone or ones that have not bothered to check the facts, either.
