Cannabis vaporizers and pre-packaged cartridges continue to grow in popularity, with sales estimated to grow nearly 50% from 2017 to 2018. Vaping delivers a different experience than smoking a joint, but it’s not easy to quantify that difference. Recently, though, scientists have looked into the question and found that vaping actually packs a more powerful punch than the traditional joint.
According to a recent JAMA study that examined cannabis consumption in infrequent consumers, people who vaporized cannabis flower experienced more pronounced effects than those who smoked the same dose. Effects increased along with the dose administered, suggesting that vaporized flower should be approached with a more conservative dosing strategy than smoked flower, especially for infrequent consumers.
While the lead author acknowledged that the study has some limitations, he echoed its conclusions in an interview with Leafly: “It was surprising, the magnitude of difference between equal doses of smoking versus vaping,” said Tory Spindle, a postdoctoral fellow with John Hopkins University’s Bayview Medical Center. Vaping “can produce drastically different impairment” for all consumers, he said.
More Efficient THC Delivery
Previous studies have shown that vaping is a more efficient THC delivery method than smoking, so researchers sought to examine its impacts on several outcomes at two doses and to compare these results with both smoking the same doses and consuming placebo doses of a THC-free substance. Researchers conducted the study between June 2016-January 2017 at Hopkins’ Behavioral Pharmacology Research Unit.
The population studied was made up of nine men and eight women with a mean age of 27.3 who were prescreened for cannabis and other drug use beforehand to confirm they all had gone an average of 13 months without consuming cannabis before the study.
Additionally, researchers assessed the participants before they consumed cannabis and then at 10 points afterwards
