What about all the bufotenine as well? Plus the ten or so other alkaloids present? Whilst I hope and am sure you take care of your toad, I feel a bit uneasy using a living creature to produce drugs. It seems exploitative to me. Thats just IMO.
5-Meo-DMT is more common in plants, so any perception that its an "amphibious" drug is just perception. As to synthetic 5-Meo-DMT and natural, of course, there is no difference. When you smoke buf alvarius venom you smoke a shitload of other things too, accunting for the experience.
Also- LOL at the above pic :D
