We won’t know the dangers and social effects of people being able to smoke 80% THC process pot, cheaply and legally whenever they want, for a few years.
THC content historically was 5 to 10%. In new GMO strains up to 20%. And it can be purified to 100%.
Physical burn-out of the brain’s cannabinoid receptors seems like a real risk. Speed users permanently mess up their dopamine receptors, leading to parkinson’s type effects decades later, even if they stop completely.
I’d like a ban on all weed shop advertising, other than some very minimal ones that provide the physical location. Or even better, a government monopoly and high prices that deter heavy use.
