The only study that has tested the bioavailability of inhaled CBD is from 2014; it found a bioavailability of about 25 percent for 100 mg and 200 mg doses of CBD using a Volcano vaporizer. (The topical lotions are even less studied; there have been no clinical trials on them at all.) This is more efficient than ingesting CBD, in the same way that vaporizing THC is more efficient than eating it. To get an effect, you should ingest a different amount of CBD than you’d inhale ... but how much is that? How much is too much?
For our review of the best CBD topicals available online, we focused only on companies which make third-party, independent lab results available to consumers. Lab results are available online, included in the order, or on request. It’s vitally important that consumers know exactly what products they’re consuming: how strong it is, and whether it has any impurities. We also focused on brands with fast, friendly customer service and easy to use websites.
Our Editor’s Pick is the tincture from CBDistillery. This tincture is available in five strengths ranging from 250mg to 5,000mg, which accommodates a wide range of THC preferences, as well as 15 and 30 milliliter containers. The tincture has a price-point that is slightly below average, making it a good option for value seekers. The tincture, which is non-flavored, routinely undergoes third-party testing to ensure safety and high quality; the testing results are available on CBDistillery’s product pages.
