I call BS on cigarette filters removing THC. I get just as high using cig filters as I do using rolled up cardboard. But its proven that cigarette HOLDERS (the tar removing ones) indeed remove THC. Not something I have tested though.
Came across these bags as I was looking for bubble bags, does anybody know anything about them? https://www.indiegogo.com/projects/test-and-review-new-extraction-products I could use some recommendations, THANKS!
