If you want to attract reindeer, there is a far, far better way, the way the Lapp people do it, to call in their herds, they scatter pieces of fly agaric (Amanita muscaria) on the snow, apparently reindeer are absolutely nuts for them. They are toxic raw, but when picked and cured with gentle slow heat , the neurotoxin in them, ibotenic acid breaks down to form the psychoactive, trance-inducing visionary drug muscimol.
I like to cook with them though more than use as a psychoactive. They have a MSG like effect on food, probably
