A surge in dangerous side effects and overdoses has put the spotlight on cannabinoid drugs that go by names like K2, Spice, Mr. Happy, Scooby Snax, and Kronic. Between March and June of this year, these drugs were linked to more than 160 cases of severe bleeding and four deaths in central Illinois. In August, more than 100 people overdosed in a New Haven, CT, park within a 2-day period.
WebMD asked two synthetic drug experts how K2 and Spice affect the body, and what risks they can pose.
