With more than 200 cases of respiratory illnesses possibly related to vaping, and no single culprit, public health experts are advising young people not to buy cannabis and other e-cigarette products off the street.
The Centers for Disease Control and Prevention on Friday warned people not to use vaping ingredients bought on the street and to stop modifying either nicotine or cannabis e-cigarette device in an effort to curb the vaping-related lung sicknesses that have alarmed health officials in more than two dozen states this summer.
