I’m not sure if you want to encourage or discourage, but you can find labs where you can legally purchase mushrooms spores, then other sites where you can buy grow bags that take the majority of the effort and chance of failure out of the equation. It’s legal and not a hard thing to find. If you grow them for ingestion… that’s illegal. If you grow them for research and educational value… that’s not illegal, so they can sell to the public.
I’ve grown for personal use your free and on for years. Pick up a couple stringers of spores and a few grow bags and you can control the process. It’s not 100% efficient, so expect 1 out of 3 bags to work, more or less, on the first attempt…
But you should be able to put together an attempt for 50-60$, and it’s a learning experience, if nothing else.
I would suggest everyone tries a reasonable amount of Sharon’s at one point or another in their lives. It’s not quite an out-of-body experience, but it lets you look at your own life through another lens to see what really resonate with you and your desires on how you live.
And he shouldn’t be taking huge doses for the sake of huge doses. It’s not about quantity, it’s about experience. If you want to walk on the edge, you should have someone that wants to walk on the edge with you. He shouldn’t be asking for babysitters. It’s fine to want to experiment, but that shouldn’t become someone else’s responsibility or journey.
