So, not a lawyer but I'll give some non lawyer advice.

You can buy spores online because the active psilocybin is not in them. They are mushroom spores (it's all so stupid to make illegal, but that's another debate)

You can grow them very easily in spare space. You grow the mycelium in a jar with brown rice flour and vermiculite, there comes a point where you expose the jar to some light to help stimulate growth. Like any natural growing mushroom. Then you put them in a container that remains humid, and again light helps them grow as theyll grow towards it. Think of a mushroom growing under a leaf off rotting tree bark in the forest, same concept.

They're decriminalized where I am (denver) and easy to find. Not legal to grow and cultivate, but do it for personal use and noone is going to bother you. Start selling or distributing, yeah, no need for that. Dont do that, federal law is still backwards and you can technically get in some trouble.

Unless you know someone who deals this is the right answer. To add to this you can get spore syringes, and sometimes kits, from smoke shops. You may have to ask around and visit a few shops. Directions are easily found online.

You are totally right, but like anything illicit, Caveat Emptor... Had a former roommate who grew magic mushrooms from a spore syringe. She was convinced they were of good quality, but she was growing them in a terrarium on the floor in a shared room with a large pet rabbit. Cleanliness and Hygiene were sorely missing. I'm not a mycologist, but even my untrained eye knew something was way off with the mushrooms she was growing. She did not end up selling them, but took her lots of convincing not too.

Moral? The closer you can get to know those growing / harvesting the better. I've always had good luck through my connections for herb. I imagine in recreational 420 states, it's harder to ask the dispensary where to get Magic Mushrooms though.
