3. Tree Base Klear
Tree Base is making unique flavored cartridges that hit hard but taste smooth.
Pros: Completely clear instead of yellow like most other pre-filled cartridges. Great balance of flavor and potency on a consistent basis. Clean tasting medicine with no itchy cough feeling on the exhale.
Cons: One of the most expensive cartridges on the market, and they’re not as accessible as some of the other best cartridges of 2017.
Why We Like It: Looks like a 0 percent nicotine e-liquid with a well-balanced flavor and potent effects.
