Growing up this cactus was in my best friends back yard. We always knew it was his mom's oldest cactus, that she has had since her dorm room days in Oregon over 32. So far this plant has lived for extended periods in Oregon, Connecticut, Texas, and southern California where it resides now.
It wasn't until 2015, after growing up around this cactus for years that I realized the unique variety this cactus actually was;
A psychoactive variety containing mescaline.
My friend's mother claimed she had no idea all along.
