I dip a tampon in THC oil and insert it in my anus. Learned it on fox news.
Unfortunately, this is inspired from a real stupid thing some young people did but with alcool. Goes too fast in their bloodstream and some supposedly ended up in a coma.
I have to believe that that's a myth. Just thinking about it for 2 seconds makes believe that nobody has ever done it. Why? Tampons have to be compressed inside an applicator for insertion. If you leave one inside the tube, it won't soak up enough liquid to matter. Take it out of the tube and soak it in liquid, well, now it's a puffed up, soggy mess. Good luck getting that into an orifice.
It is called 'boofing' and the number of people that do it is more than 0. Because of how the body absorbs substances that way, people can get a stronger effect than consuming them orally.
