The biography

Also known as Sonoran Desert toad venom, a 5-MeO-DMT experience can be a blissful cosmic ride or as author Michael Pollan noted, ‘Like being strapped to the outside of a rocket…terrifying.’ 

This second eBook by Forbes magazine writer David E. Carpenter follows the sitters, scientists, and enthusiasts of Sonoran Desert toad venom and the many people looking for solace, healing, and meaning in life through the 5-MeO-DMT molecule. 

5 & I  also takes a look at the short history of toad venom use (the popularity of which grew in 1983 with the classic pamphlet Bufo alvarius: the Psychedelic Toad of the Sonoran Desert by Ken Nelson); the current rise of toad conservation & synthetic options; and the inevitable future of this novel drug as a pharmaceutical tool for mental health.
