Additionally, numerous scientists, doctors, and researchers are concerned with the safety of inhaling CBD oil because little is known about the long-term effects. What’s more, when vaping devices are heated, a chemical reaction takes place in the vapor, which could pose additional risks to the lungs, especially in young people.

CBD oil is extracted from the flowers and buds of marijuana or hemp plants. Typically, it does not produce a “high” or intoxication because it contains very little, if any, tetrahydrocannabinol (THC). In fact, CBD oil is only permitted to contain less than 0.3% of THC. CBD oil is legal in states where medicinal or recreational marijuana is legal. Meanwhile, several other states have CBD-specific laws on the books even though marijuana is not yet legal there.
Is Vaping CBD Oil Safe?
To make matters worse, this lack of certification has lead people to sell vaping liquid they claim contains CBD oil when it actually contains harmful chemicals, which is injuring and killing people in the process. To determine the extent to which this is occurring, the Associated Press (AP) commissioned a study to analyze the contents of nearly 30 oils claiming to contain CBD.
Although the CDC has traced many of the EVALI hospitalizations back to vitamin E acetate, a substance used to dilute oils used in vaping, the risks of vaping CBD oil are not without risk, especially if the vape pens are obtained from illicit dealers, online sources, or friends. At least 26 of the EVALI cases were hospitalized after vaping CBD oil.
Because this testing was a such a small sample, the AP noted that their sampling is not representative of the entire CBD market. However, their testing does show just how risky it is to vape CBD oil when there is little to no regulation of the product. Vapers have no idea what they are getting when they take a puff.
Generally speaking, vaping is an unsafe practice regardless of what substances are in the vape pen. And, CBD oil is no exception. In fact, the Centers for Disease Control and Prevention (CDC) has recently linked vaping products to an outbreak of nearly 3,000 lung illnesses that were so serious that even young people were being admitted to the hospital. Meanwhile, nearly 70 people have died from what is now being called EVALI (e-cigarette and vaping associated lung injury). And, the CDC believes thousands more may have admitted to the hospital with lung issues related to vaping.
Quartz contacted two manufacturers of CBD vape pens that contain MCT oil, and neither has replied to our messages. Bloom Farms’ unflavored CBD vape contains no MCTs or other cutting agents. The company’s flavored CBD vape pens contain trace amounts of MCTs—less than 0.3% according to a company representative—and the company is currently phasing them out.
The northern California-based company Bloom Farms—which has been in the cannabis extracts business since 2014—started selling hemp-derived CBD products online in January, and puts them through the same testing processes as their products with THC, which are under the strict purview of the California Bureau of Cannabis Control. Customers can also download a certificate of analysis from Bloom’s website that provides test results from a third-party lab, but that’s far from standard in the CBD space.
Benowitz said the effects of vaping MCT oil, however, is an understudied area.
You might be safer with weed
If you’re in a state where weed is legal, you might be safer smoking (or vaping) it, by going to a licensed dispensary for a high CBD-strain or vape that’s subject to the same regulations that cannabis is. In states like California and Oregon, where cannabis is regulated by state agencies, products with THC are subject to testing for contaminants such as pesticides, heavy metals, solvents, and mold-related toxins. Again, hemp-derived CBD products are currently subject to … nothing.
“It’s totally horrifying to me,” says Katie Stem, an herbalist who cofounded the Oregon-based cannabis company Peak Extracts in 2014, and has researched plant medicine and chemistry at Oregon Health & Science University. “People should not be cutting [cannabis extracts] with any sort of culinary lipid.” Stem says that with an extraction process using carbon dioxide as a solvent, it’s possible to create a vape-able distillate containing only plant material, without any additives.
Neal Benowitz, a professor of medicine at the University of California, San Francisco, who has studied the pharmacology of e-cigarettes, says that CO2 extraction process is “pretty clean,” and the results are well-known.
“People have been vaping them for a long time, and haven’t had a problem,” he says. “That seems to be relatively safe, and that’s a solvent that dissolves them. The question now is, when you start messing with that process, what are you adding to it?”

Medical cannabis can be consumed in a plethora of ways, depending on your preference. You can consume it in baked goods or drinks, with a water pipe or rolling papers, in pill form or as a nasal spray, and of course, with a vaporizer.
How to Vape Cannabis
For its part, the FDA has started to rein in vaping companies by sending warning letters to manufacturers who market their products using false or misleading claims about their contents. Even so, vape pen users can still purchase bootleg versions of products online or even make their own at home—neither of which are guaranteed to be tested for safety.
Both smoking and vaporizing cannabis are associated with severe and potentially life-threatening conditions. Fortunately, there are safer ways to consume cannabis that don’t involve secondhand smoke and aren’t harmful to your lungs.
Some of the perceived benefits of using a vaporizer include:
