Yes, but not always. Of course 24 mg liquids with the capacity for TH will have the most vs. those same liquids at a lower percentage, but not all 24 mg liquids have ample TH; and interestingly, take those liquids with the capacity for nice TH and they can have better TH at 18 mg over other liquids at 24 mg. Ratios matter too, but not always. As a general rule of thumb, the higher the VG, the lower the TH (meaning the higher the PG), but liquids sold at AVE.com have great TH (Boba's Bounty, Gorilla Juice and Gamel.) There really aren't any rules that guarantee TH, but it generally does start with higher nic first, then ratio, then flavorings (hard to know those details though), and then from maker. And don't forget delivery device and wattage. Oy vey . LOL
