I bet it's a combination of booze and prescription anxiety/stress meds...if she was smoking dope, people around here and reporters would surely smell it on her. Marijuana's peculiar odor is deep penetrating and nearly impossible to hide.

I agree about the odor of the smoke, pungent, (skunk smell), penetrating, lingering in any space it has been used, and impossible to hide--especially around people who don't partake.
There are industrial grade odor removers that will kill it, though (the same stuff that gets the vomit smell out of airplanes). Ordinary air fresheners won't cut it or cover it.
Edibles, mannnnn...
You don't have to smoke it.
Back in the day, it was brownies or cookies, now they have a wide spectrum of edibles, including gummies.
