The challenge with regulating cannabis advertising is that dispensaries have turned their storefronts into highly effective advertisements. Few storefronts in NYC are more eye-catching.
It's hard to regulate advertising when the store itself is the ad.
Same is true for (many) the other vices. Doesn't seem terrible for them. Much better than currently where Kalsho is twice in every NFL break, WNBA (Valkyries!), MLB, Yahoo Finance and commercial breaks on TNT and various Roku channels.
Last time I visited the US, I had never seen as immense an advertising banner as the one on the side of the building in LA advertising cannabis.
