I strongly disagree. "Presently stoned" means everything. If a person lit up last night, they are not "under the influence" the next morning. I have never heard of a stoner hangover. If a person is not under the "intoxicating effects" of weed they will pass a SFST with flying colors, because they are not "under the influence" .
Not sure what you mean by "lack of convergence".
I get that you don't understand, because you know not what you speak of.....it's OK.
Fyi presently stoned means nothing in a legal sense. But keep trying...
BACK ON TOPIC. Weed has nothing to do with it. The industry has everything to do with it
