"Twitter does not permit advertising for illicit substances, not to mention herbal drugs, thus eliminating CBD completely."
This advertisement policy is only applicable for "products that are being promoted by means of paid advertising."
Running a Google AdWords advertisement promoting CBD products may cause the ad being taken down and the marketer will possibly be penalized from publishing future advertisements, even if they are not CBD marketing ads.
The company recently asked a number of CBD companies to participate in a trial run for CBD advertising. The results are yet to be revealed.
Instagram policies regarding CBD advertising are similar to the Twitter rules.
"Instagram users are not penalized as often as Twitter users when advertising CBD oil and related products, since Instagram does not seem to monitor CBD marketing quite as much as Twitter does. The app can permanently shut down the marketer account if it tries to specifically sell a product."
YouTube’s Community Guidelines stipulate that harmful or dangerous content is prohibited. Content about medical marijuana is currently allowed. Videos that discuss "such substances for educational, documentary, and artistic purposes as long as they do not glorify illegal or dangerous use of the product."
