Research on psychedelics is making a comeback, and this science-minded TV host says that's a good thing. Jason Silva, host of National Geographic Channel's "Brain Games," is encouraging scientists to explore the medicinal use of psychedelic drugs -- saying they can efficiently be used as "tools" to explore the human mind. On Friday, Silva told HuffPost Live that while you can "abuse any tool just like you can abuse sugar," research has found that using psychedelics in "responsible contexts" may hold promise as therapeutic interventions for a number of medical conditions. "Some of these things that are coming out about MDMA for people with [post-traumatic stress disorder], psilocybin mushrooms for people who have terminal cancer, apparently it's like 10 years of psychotherapy compressed into three hours," Silva said in the interview with host Josh Zepps.
