I’m sure overall usage numbers are up because I know a lot of people who started using it after they could buy it legally, but those people are all also infrequent users and I’m sure are not driving high. The people who would be deterred by weed being illegal are probably all in the “won’t drive stoned” category. (I’m sure many infrequent users pre-legalization, myself included, were never much worried about the legality but don’t drive high because we like being alive, and we continue to not do so now.)
