collapses have also occurred in the hemp/CBD product space.
The resulting
competitive pressures may be particularly acute in areas with a high
concentration of cannabis stores.
Legalization also expands opportunities for professional marketing. Before
policy liberalization there were no billboards, cannabis marketing executives,
industry associations with lobbyists, or much in the way of brands—these are all
fixtures of the contemporary market. The emerging evidence suggests that
legalization is associated with an increase in the number of adults who use
cannabis in the past month
as well as an increase in their frequency of use.
While the evidence with respect to youth has mostly found a null or negative
relationship for these outcomes so far,
one study found that after legalization
there was an increase in the number of people aged 12-17 and 26 and older
meeting clinical criteria for cannabis use disorder.
And as noted in Section
I.F, there are growing concerns about the health effects of higher-potency
products.
Also as noted in Section I.F, cannabis stores are already concentrating in
BIPOC neighborhoods and places with higher levels of deprivation, and high
outlet density is associated with adverse outcomes. One way to address this is to
grant licenses with the stipulation that only so many cannabis retailers can be
concentrated in a geographic area.
