Sort of. Its illegal to ship any psilcybe specimen to Idaho, cali, and some other state I believe. Most legit vendors don't... but you can play your luck out with one of them!
Like roulette... you may lose some money but i've heard stories of legit sites slipping a few through the cracks. I think finding them in the wild and collecting spores is a choice some places I dont know about were you live. And look around for like agg trades and things also maybe building up some rep and try talking to people on shrooms chat sites. I've seen many of these other sites members trade and you may find some in your area thats a long term solution of course.
