Ok this was funny, but serious. I have never seen such a spiny sensitive Nopal. I figure they must be edible due to having so many spines to protect them. BUT, I think you would die if you swallowed any of the micro super light spines with the ability to get airborne.
I made the mistake of trying to get a piece to transplant into my cactus garden. I realized soon enough that my hands and arms were covered with burning micro spines. Just then a gust of wind picked up and I witnessed the true potential danger these spines have. All the spines that were on my arms and on the cactus where I must have disturbed it became airborne and blew around and off in the wind. I ran leaving the cactus piece I had selected and quickly changed my mind about having that thing anywhere around my house. Had 1 of them blew into my eyes I woulda been in trouble. Spines in the eyes aint no good. STAY far away from these Nopal Cactus!! Any cactus with a nasty look should be left well alone. Ira
