Pot inhaled through a vape device produces a more powerful high — and often with more deleterious side effects — than the smoked version, a new study finds.

At the same level of THC, the psychoactive ingredient in marijuana, vaping led to higher blood concentrations of the chemical than smoking, as well as higher levels of cognitive and psychomotor impairment and a higher incidence of adverse effects, such as vomiting, anxiety, hallucinations and feelings of paranoia, according to the report, published Friday in JAMA Network Open.
