If they are allowed to advertise, it should be 100% fact based in it’s approach. No more camels wearing sunglasses while smoking or sexy actors at a rooftop party drinking alcohol in front of a magnificent night panorama of skyscrapers while smiling and laughing together. No happy people skipping through the sunflowers after shooting up black tar heroin. No partner advertising between the movie TRON and hallucinagen sellers. Sellers could basically only list their cost per quantity, info about the manufacturing process, and any purity measurements with no emotional appeals, bandwagoning, colorful cartoon characters, etc. With something potentially addictive and harmful, we have a moral duty not to allow anyone who sells using logical falacies and dark patterns to have a platform.

Warning lables should be super clear and the package should be otherwise 100% plain. Some substances may still warrant a ban, I’m undecided, but if they are allowed, they should probably not be advertised. People who want them, will be able to find them.
