Is it safe to vape cannabis?

E-cigarettes and cannabis vaporizers have been on the market for years. Manufacturers tout them as a healthier alternative to smoking, but a surge in the mysterious vaping-linked illness has caused health officials and lawmakers alike to sound the alarm. The Center for Disease Control has counted 450 cases of potential vaping related illnesses across 33 states and one U.S. territory.

People with it usually experienced shortness of breath, coughing, and chest pain before they deteriorated to the point that they needed to be hospitalized. Many victims ended up with acute respiratory distress syndrome, a life-threatening condition where fluid builds up in the lungs and prevents oxygen from circulating. Some have even died.
