I mean not like literally poisonous but, just have a little stinging venom or something when you i don't know happen to put your hand on one?? hahah.. well like seriously, this weekend i was with my family picking pinons and i was crawling on the ground. Trying to be quick about it because it was raining. I wasn't watching where i put my hand and i put most of my pressure on a cactus. I don't know what kind of cacti is was but i live in the south west, new mexico to narrow it down. Northern part. so yeah i don't know hahah? is there so kinda of toxin that gets released when you accidentally stab yourself with its needles? Any ideas?
