Vaporizing Cannabis Significantly Reduces CO Exposure Compared to Smoking, Study Finds

Smoking is my absolute favorite method of cannabis ingestion - from grinding my herb and rolling a joint, to massaging the doob between my fingers, to the inhale and exhale. A vape doesn't do it for me in the same way for some reason - I think because it doesn't have the ceremony that smoking a joint does - but that doesn't take away the fact that vaping is a healthier delivery method. Multiple studies over the years have come to this conclusion - read about the latest here. —Kaisha-Dylan McMillan, Editor, DT

A new clinical trial that will be published in the upcoming June issue of Drug and Alcohol Dependence has found that vaporizing is a safer but just as effective method for consuming cannabis compared to smoking. The study, conducted by researchers from the National Institute on Drug Abuse, compared the subjective physiological effects and expired carbon monoxide (CO) levels after vaporizing, smoking, and orally-consuming cannabis.

Participants in the study consumed a placebo or cannabis containing 6.9 percent (about 54 mg) tetrahydrocannabinol (THC) via vaporizing, smoking or oral methods.

All of the participants that vaporized and smoked cannabis reported significant elevated physiological effects immediately after consumption, while only occasional cannabis users saw a significant physiological after oral dosing. This suggests that vaporizing and smoking are more ideal consumption methods for users interested in the most immediate and potent effects. Those who regularly use cannabis, however, may not experience as significant effects through oral methods because they develop partial tolerance.

Additionally, the study found, smoking produced significantly increased expired CO concentrations compared to vaporizing 15 minutes to 6 hours following consumption. Both vaporizing and smoking release the active compounds of cannabis by heating the material. However, vaporizers use convection or conduction heating and heat the cannabis material to a much lower temperature. This heating technique avoids combustion, eliminating the release of harmful toxins like carbon monoxide.

“Vaporized cannabis is an attractive alternative for medicinal administrations over smoking or oral routes; effects occur quickly and doses can be titrated with minimal CO exposure,” the study concludes.

Carbon monoxide is a colorless, odorless toxic gas that blocks the blood’s ability to carry oxygen to body cells. CO is harmful to your body at any level and can cause fatigue, headache, dizziness, nausea, mental confusion, rapid heart rate, and death. Long-term exposure at lower levels can lead to heart disease.

Previous studies investigating the differences between marijuana smoking and vaporizing methods have come to the same conclusions. In 2007, researchers at the University of California concluded that “vaporization of cannabis is a safe and effective mode of delivery of THC” after finding that a cannabis-vaporizing device effectively delivered the same levels of THC as smoking, but without causing an increase in CO levels. We recently detailed the benefits of using a vaporizer and you can read more about why it’s a healthier alternative here.

Cannabis has been legalized for medical purposes in 28 states and Washington D.C., and eight states plus Washington D.C. allow cannabis to be used recreationally by adults.
