In fact, I used to argue with my professor, Richard Evan Shultes -- who is a man who sparked the psychedelic era with his discovery of the magic mushrooms in Mexico in the 1930s -- I used to argue that you couldn't classify these tryptamines as hallucinogenic because by the time you're under the effects there's no one home anymore to experience a hallucination. (Laughter) But the thing about tryptamines is they cannot be taken orally because they're denatured by an enzyme found naturally in the human gut called monoamine oxidase.
Ustvari, znao sam raspravljati sa svojim profesorom, Richardom Evanom Shultesom -- čovjekom koji je izazvao psihodeličnu eru sa svojim otkrićem magičnih gljiva u Meksiku u 1930-im -- Tvrdio sam da se ovi triptamini ne mogu klasificirati u red halucinogena zato što u vrijeme kad ste pod efektima nema nikog kod kuće tko bi doživio tu halucinaciju. (Smijeh) Ali stvar s triptaminima je da se oni ne mogu uzimati oralno zato što ih razgrađuju enzimi koji su prirodni sastojak crijeva ljudi, to su monoaminske oksidaze.
