“We did a study some years ago where we experimented with all the CBD merchandise on the market to ascertain if they were accurately labeled ,” Loflin says. Her team checked out oils, tinctures, and vape liquids containing CBD (another major cannabinoid) and found out that the liquids were mostly inaccurate—”by a large margin,” she says, that means that they didn’t contain the amount of cannabinoids the merchandise labels said they did.
“It causes you to think deeply concerning how those are being made and causes you to raise your eyebrows at the businesses manufacturing them,” Loflin says. However, she additionally notes that she and many different colleagues have all assumed that the cannabis vapes involved in these cases don’t seem to be those who use the plant itself (to be clear, this can be a guess, not a fact—something else we still do not really know).
Even in the category of e-cigarettes, there’s plenty of variation, Dr. Neptune says. “We’re currently on the third or fourth or fifth incarnation of those devices,” and that we don’t have the knowledge of how precisely they’re composed, how they’re heated, or what the precise effects are of delivering these heated ingredients to the lungs.
Essentially an e-cigarette contains a liquid solvent (like propylene glycol or vegetable glycerin), nicotine, and a some type of aroma, Humberto Choi, M.D., a pulmonologist and critical care specialist at Cleveland Clinic said. However as a result of the FDA not knowing the precise products patients were using, we don’t know precisely what ingredients they contained. And the actual fact that a lot of vapes enable customers to combine or refill their own e-liquids adds another level of risk and quality.
