Vaping and CBD oil are both known for their quick absorption and bioavailability rates. But when deciding, we often wonder, which one is better? While vaping might be the more in-thing to do, it might not necessarily be better than sublingual application.

Sublingual Application vs. Vaping

Applying the tincture sublingually involves placing a recommended number of drops under your tongue and holding it in contact with the sublingual tissues for about 2 minutes for best results.

Whereas vaping involves heating the oil with a specialized pen into a vapour that is then directly inhaled into your lungs.

The Bioavailability

Bioavailability is one of the crucial factors to consider when choosing the best delivery method for consuming CBD. It can be explained as the given amount of CBD that manages to get into your bloodstream.

Both sublingual and vaping bypass the digestive system and head straight through to your bloodstream, but because of the different pathways, the dose that gets absorbed by your body varies.

Vaping takes a faster and least resistant route, allowing more CBD to be absorbed. Whereas with the sublingual application, the oil starts to get broken down by your saliva and has to work its way through the high cellular water content. However, the effects of vaping only last for a short period, whereas the oil stays in your system for longer.

Possible Risks

While placing the CBD oil under your tongue may have minimal side effects (provided that you buy quality oil and don't take too much for your system), vaping can have some dire consequences:

  • Ingredients such as propylene glycol may be carcinogenic when exposed to high temperatures.
  • Some heated compounds may get deep into the lung tissue, causing serious lung diseases.
  • The presence of nicotine may increase your chances of developing an addiction.

That being said, there may be ways to reduce the risks by ensuring you only buy quality oil and vape pens from a reputable store.


Ultimately, whether the sublingual application is better than vaping is up to personal discretion. However, when looking at the risks involved, vaping is probably not a good idea.
