If you shot up spores? Iv'e wounderd if you'd get a fungul infection and die or if nothing would happen at all.
putting things directly into your blood stream is a bad idea. everything that is in your veins is carried back to your heart. you'd probably die a pretty painful death. if you have spores, it would be a much better idea just to grow.
spores contain no active psilocybin or psilocyn, or baeocystin... so it wouldn't do anything but kill you. lol. all they contain is mycelium growing substances.
... thats why its legal to buy spores in most states, they dont actually contain any psilocybin. sorry, but honestly thats just a dumb thought to shoot mushroom spores lol
i dont really think they would grow inside you, you dont have the right kinda nutrients inside you and the temp is completely wrong... lol. nearly 100 degrees is way too warm for mycelium... the prime temp is more around 86 degrees f.
