Benowitz said the effects of vaping MCT oil, however, is an understudied area.
And of course, not all CBD vapes are created equal. Many extracts sold in vape pens and cartridges are diluted with other substances, such as medium-chain-triglyceride, or MCT, oils—fats that are frequently derived from natural sources such as coconut oil. While these are known to be safe to eat—and are often found in CBD tinctures—there’s little if any evidence that it’s safe to vape them, despite some manufacturers touting them as an all-natural ingredient.
Some of those companies are those that come from the cannabis industry, and therefore have years of experience with extraction and testing.
You might be safer with weed
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.
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.
“There’s no regulations, there’s no one telling companies what to do,” says Jonathan Miller, general counsel for the trade group US Hemp Roundtable. “I don’t want to say it incentivizes bad behavior but it certainly doesn’t crack down on bad behavior.”
“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?”
However, even though vaping CBD tinctures might not be toxicin most cases, doing so is far worse than ingesting CBD vape oils.
There’s been some confusion around the exact nature of CBD tinctures and CBD vape oil and the consumption options they come with, especially around the former. Its important to clear it up as consuming even the best product the wrong way often defeats the whole purpose.
Clearing the air starts with clearly defined notions of CBD tinctures and CBD vape oil.
Lastly, some tinctures have an alcohol base. Not only is inhaling alcohol highly unadvisable, which may or may not happen, but there’s a slight risk of the tincture catching fire. Better safe than sorry.
Can You Vape CBD Tinctures?
CBD tinctures refers to liquid CBD oil products, designed to be consumed by mouth, or in other words, ingested. In short, CBD tinctures and CBD oil are interchangeable terms.
The confusion around this question stems from CBD vape oils being suitable for oral consumption as well as their ingredients, including the thinning agents, are considered safe and non-toxic. That doesn’t go to say they should be ingested this way since that’s not the optimal way to consume them.
Vaping is one of the most effective and popular ways to use CBD. With such a diverse range of products available, it’s important to know which oils are suitable for vaping, and how you can verify their quality. This guide covers the essential things to know about shopping for CBD vapes and CBD vape juice, plus how to use them properly. One caution: if you use prescription medications, you should always consult your doctor before incorporating CBD into your regimen.
Research has shown that CBD is very low in toxicity. A study from 1981 determined the LD50 for CBD to be 212 mg per kg of body weight when given to monkeys intravenously. This suggests that humans must consume hundreds of times the average daily dose of CBD (30 mg) in a relatively short period of time to be at risk for overdosing. It is highly unlikely that anybody will ever take enough cannabidiol to induce lethal consequences.
What is CBD?
A typical CBD vape cartridge containing 100 mg of CBD delivers about 1-2 mg CBD with each puff. If you’re using a CBD vape pen or tank, you’ll be taking in a bit more CBD per puff, depending on your device and the strength of your CBD vape juice.
The average CBD user takes an average of 10-30 mg per day. For serious conditions like pain and inflammation, some users take as much as 200-1000 mg per day. See our full guide for more specifics on how to determine your ideal CBD dosage.
The Americans for Safe Access stated at a 2016 medical cannabis conference, “To date, there has never been a single well documented case of human fatality attributable to an overdose of cannabis or its components, and no experimental or non-extrapolated LD50 can be attributed to a toxic or lethal overdose.”
