Jay Jenkins holds a Yolo! brand CBD oil vape cartridge alongside a vape pen at a park in Ninety Six, S.C., on Wednesday, May 8, 2019. Jenkins says two hits from the vape put him in a coma and nearly killed him in 2018. Lab testing commissioned by AP showed the vape contained a synthetic marijuana compound blamed for at least 11 deaths in Europe. Jenkins was interviewed as part of an AP investigation into the dark side to the booming CBD industry, in which some people are cashing in by substituting cheap and illegal synthetic marijuana for the natural cannabis extract.
