DMT, the next best allergy medicine? My friend gave me some  DMT in the form of tiny crystals and told me to snort it. It was one of the single most unpleasant experiences of my life due to the immense pain in my nostrils. However, after this experience, I have not had a single issue with having that side of my nose being stuffy whatsoever. At the time I snorted it, I was having really bad allergies and couldn't go an hour without needing to blow my nose, but now, I'm perfectly fine.
