We're talking the difference between 2 and 200 milligram doses of THC here in terms of how it affects people on these levels. One comes in a soda at the store down the street from me. The other you can't get like that and might send your average recreational user to the hospital with a panic attack.

I'm wondering also if one of the big factors here is oxygen deprivation. These sound kind of like the same kind of numbers of cognitive decline that you see in air pollution, maybe just generally clogging your lungs with smoke could be comparable.
