Can Vaping CBD Cause a Failed Drug Test or Get You High?

CBD has become hugely popular recently, especially among vapers. Whether you use CBD vape juice or take CBD oil sublingually, it’s important to familiarize yourself with the various types of CBD on the market.

Not all “CBD oil” is made for vaping. E-liquid contains no actual oil (even though it may be called oil), but some CBD products intended for oral use really are oil-based, and are not safe for inhalation. Learn the difference before you vape CBD oil.

CBD oil is extracted from hemp -– a cannabis plant that has been selectively bred to be high in CBD, and low in THC. Some hemp plants contain tiny, trace amounts of THC — the primary intoxicating compound in marijuana. However, vaping CBD oil will not get you high, because CBD is non-psychoactive.

If you’re wondering whether vaping CBD will cause you to fail a drug test, that is a legitimate concern. Imagine using CBD, then getting fired because you test positive for marijuana. It would be devastating, especially if you’ve never even used marijuana! The reality is, while it’s technically possible, the chances are extremely slim that you’ll ever fail a drug test from vaping CBD, especially if you follow these important tips.

CBDfx Terpenes Vape Pens are disposable vapes filled with 50 mg of full spectrum cannabidiol and flavored with real terpenes. Terpenes are organic compounds found in plants that give each hemp strain its own unique flavor and character. CBDfx Terpenes Vape Pens come in four natural strain-specific varieties.

Avoid marijuana-based CBD oil

CBD vape juice and CBD cartridges for vaping are often derived from industrial hemp (not marijuana). If you do not want to get high or fail a drug test, do not use CBD oil derived from marijuana. Stick with CBD isolate-based products. Hemp plants are rich in CBD, which is a non-psychoactive cannabinoid. But most hemp naturally contains small amounts of THC, the main psychoactive component in marijuana.

The good news is that while marijuana sold in dispensaries has anywhere from 10 to 30% THC, most hemp used for CBD oil is generally below the legal limit of 0.3%, which isn’t enough to actually get you high. Marijuana has roughly 20-100 times the amount of THC present in hemp.

There are a number of companies that have developed a way to make CBD oil that contains virtually no THC at all by using 99% pure CBD crystalline isolate powder. Since isolate is virtually free of other plant matter and cannabinoids, the risk of testing positive when using it is practically zero.

Avoid full spectrum CBD

There are three main categories of CBD oil: full spectrum, broad spectrum and CBD made from isolate. If you’re concerned about failing a drug test, then avoid full spectrum cannabidiol! Only use broad spectrum and vape juice made from CBD isolate.

CBD vape juices made from pure CBD isolate typically contain the lowest levels of THC. Cannabidiol isolate is a powder that is at least 99% CBD — used for making CBD oil that has little to no THC. Broad spectrum CBD is also practically THC-free, but usually contains added terpenes and/or other cannabinoids. These terpenes can alter the experience and provide additional effects beyond those of pure cannabidiol. This interaction between CBD and other terpenes and cannabinoids is an example of what’s called the “entourage effect.”

Full spectrum CBD oil, on the other hand, is extracted from raw hemp or marijuana. It contains CBD, in addition to other cannabinoids and terpenes. It sometimes may contain more than 0.3% THC. This product is common in cannabis dispensaries. If you buy CBD from a dispensary, ask them to show you documentation of its THC content.

  • Full spectrum CBD – Can be derived from hemp or marijuana and may contain 0.3% THC or higher, plus additional cannabinoids and terpenes. They are generally made by CO2 extraction or a solvent-based extraction method.
  • CBD from isolate – CBD crystal isolate is a fine crystalline powder that typically contains 99% pure cannabidiol. It’s mostly free of other cannabinoids (including THC) and residual plant matter. It’s generally used for making CBD vape juice that has little to no THC.
  • Broad spectrum CBD – Gives you the “best of both worlds”. Broad spectrum CBD oils are also made using CBD isolate, so they contain virtually no THC, but they do contain organic terpenes and other cannabinoids.

Always look for lab test results

Trustworthy CBD manufacturers are generally pretty transparent. Most publish a certificate of analysis, issued by a legitimate third-party laboratory. These labs analyze CBD oil to verify the claimed CBD and THC levels. They also check for contaminants and other potentially harmful substances.

If you are subject to drug testing, always look at lab results to make sure your CBD oil contains no THC. Don’t take chances on CBD oil that hasn’t been thoroughly tested. Make sure the lab test results are relatively up to date, and from a credible lab. Just do a quick search for the brand name, find the official website and analyze the certificate of analysis. If you can’t find a legitimate lab report for the product, it isn’t worth buying.

How to Not Fail a Drug Test or Get High Vaping CBD Oil

Only stick with trusted sources

There have been a few documented cases of CBD products being sold that didn’t contain the advertised amount of CBD. Some of these products also contain so-called “synthetic cannabinoids” (like spice or K2), which are not actually cannabinoids at all, and can make you uncomfortably high. (They’re generally illegal too.)

The reality is that most of the products on the market today have gone through a legitimate third-party screening process and do not contain synthetic cannabinoids, especially after these incidents. Don’t waste your money on poor quality products.

Check those lab tests to make sure you’re getting CBD oil that doesn’t contain THC. Some of the cheaper brands use low-quality ingredients which may still contain other cannabinoids and plant matter. Your best bet is CBD oil made from high-quality CBD isolate that contains no THC at all, with up-to-date independent lab tests to back it up.

A good rule of thumb is to not buy CBD products from random smoke shops, gas stations or corner stores unless you know exactly what you’re getting. It only takes a few minutes to read consumer and professional reviews to find out which brands are to be trusted.

Will CBD cause a failed drug test?

Studies have shown that it would require ingesting at least 0.6 mg THC per day to screen positive at the standard 50 ng/mL cutoff point. Subjects ingested 0.45 mg of THC oil and still didn’t meet the threshold for THC, according to a scientific study.

If you’re only taking around 200 to 300 mg of CBD oil a day, you’re unlikely to fail a drug test. Even full spectrum hemp extract contains well below 1% THC, so you would probably have to vape several bottles of liquid daily to meet the standard threshold for THC.

The bottom line is that in most cases, if you’re using a verified high-quality CBD oil made from industrial hemp or CBD isolate, it most likely won’t get you high or set off alarm bells on a drug test. Be diligent about which brands you choose and where it comes from.
