I like the idea of capping THC potency (delta-9), what we have now isn't what we the general public aimed to legalize this is just competition keeping up with consumer demand the consequences should fall on the vendors and growers on a licensing perspective, just like alcohol or food vending
I don't think the general public knows (or cares) much about potency, actually.
Also, they were plenty aware that legalization wouldn't stop a certain segment of the population from harming themselves through overconsumption, no matter what was done to try to convince them otherwise.
