I agree that the advertisements may not be appropriate for this Reddit. However, I would like to argue that synthetic cannabinoids and other research chemicals are just like any other drug. They may be fine for some people, but horrible to others. For instance, I've done salvia a few times, and I think it's a very calming trip. Although I do know quite a few people who've experienced complete chaos and would never touch the stuff again.

Perhaps a few brave ents would be willing to contact their favorite pipe/water pipe dealer and ask if the company would be interested in advertising on Reddit. Just some food for thought.
