A new study conducted from June 2016 to January 2017 at the Johns Hopkins University of Medicine Behavioral Pharmacology Research Center in Baltimore administered doses of 0mg (placebo), 10mg and 25mg of vaporized (via a Volcano vaporizer from Storz and Bickel) and provided cannabis to participants to study the differences of effects between the two modes of administration and as a function of dosage. The study concluded that there was a significant difference in the effects between vaporized cannabis and smoked cannabis.
The study assessed the effects of cannabis in subjective terms and by performing cognitive and psychomotor performance tests. She also monitored cardiovascular vital signs and THC levels in the blood.
The discovery of this difference between vaporized and smoked cannabis (also show on this website vaporisateurcannabis.com) in adults who do not use cannabis regularly may inform the choice of health professionals in referring their patients or specific cannabis policies and regulations
