Vaping Could Make Medical Pot Healthier

A new type of smoking called "cannavaping" — using e-cigarettes for vaping cannabis — may help people use marijuana for medical reasons, according to a small, early study. Smoking conventional marijuana cigarettes may lead a person to inhale high amounts of the toxic contaminants that are released when marijuana is burned, the researchers said. In contrast, cannavaping might provide a way to avoid inhaling high levels of these contaminants, the researchers said.
