Weird, kinda gross question for you all.

Every time I take shrooms or lsd, they always back me rather mucousy. My chest and my nose. It's happened ever since I started tripping over thirty years ago. I was just curious if anyone else gets a similar experience? With them both affecting the same serotonin receptors, maybe that's some kind of connection to it? It's not so bad as to stop me taking them, as you can probably guess from over three decades of using psychedelics.
