Blood THC concentration has no correlation with current level of impairment the way it does with blood alcohol. "far exceeding most state impairment limits" specifically seems like it was written by someone trying to make a technically correct statement that is essentially wrong. The "legal limit" for THC is either 0 or there isn't one.

Even if there was such a limit, people who use cannabis for medical reasons would have to be exempt.

No..impairment is impairment whatever the reason for getting impaired is. Prescription meds get you in trouble in DUIs too.
