On Wednesday, Twitter revised its advertising guidelines to permit the promotion of cannabis on its platform in states where it is legal, while following federal regulations.
How it works. According to a policy update published on its website, Twitter will only allow a limited number of cannabis ads. CBD and THC firms are permitted to advertise their brands and provide cannabis-related information, but the ads must not sell or promote cannabis products, with the exception of topical (non-ingestible) hemp-derived CBD items that comply with the government’s 0.3% THC threshold.
