Vaping CBD is fast becoming a popular means to ingest the cannabinoid, where it enters the lungs and is diffused via the alveoli into the bloodstream. Some estimates put the bioavailability of vaped CBD in the region of about 50 to 60%, meaning that for every 10mg of CBD you ingest by vaping, around 5-6mg reaches your bloodstream. Another advantage of vaping CBD is that the onset of effects is more rapid, which is of particular benefit to those using CBD to treat seizures or anxiety, where rapid relief is key.
It is estimated that the oral bioavailability of CBD is about 15%, meaning that for every 10mg of CBD you ingest orally, only around 1,5mg reaches your bloodstream. One of the reasons for this is that when the CBD enters the digestive system, it must pass through the digestive system and liver, which break it down via stomach acids and enzymes. Another reason is that CBD is hydrophobic, meaning that it isn’t water soluble and rapidly diffuses out of the blood and into fatty tissues. One can partially offset these effects by taking oral CBD oil sublingually or by considering a liposomal CBD. Liposomal products encapsulate the active ingredient in a lipid (fatty acid), thereby making it more resilient to the destructive effects of the gastrointestinal tract, and more hydrophilic, or water soluble.
Most vape devices consist of four components: a battery, an atomiser (heating element), a mouthpiece and a chamber to hold the vape liquid, otherwise known as vape juice, e-liquid or e-juice. The heating element vaporises the liquid in the chamber, and the user inhales the vapour through the mouthpiece.
Can I Vape Regular CBD Oil?
In short, no. Vaping CBD oil won’t work because it’s too viscous or thick for use in a vape device and hence manufacturers typically blend it with a thinning agent such as propylene glycol, polyethylene glycol or vegetable glycerin.
Some users are allergic to some of the chemicals and compounds produced by vaping. Some studies have found disconcerting amounts of metal particulates and contaminants such as lead and cadmium in vapes. The primary compounds in vape liquid are propylene glycol, polyethylene glycol and vegetable glycerin. Users sensitive to any of these chemicals may experience headaches, sinus irritation, nausea or even more severe allergies such as swelling or breathing difficulty. Propylene glycol and polyethylene glycol allergies are relatively common, while vegetable glycerin allergies tend to be rarer. Furthermore, both propylene glycol and polyethylene glycol can break down into carcinogenic compounds like formaldehyde and acetaldehyde.
While vaping CBD may not be for everybody, it’s certainly popular enough to warrant investigation for those looking for a means of accelerating the effects of CBD.
