Analysis

The ranking

New York has the deepest vape record in this index, with thousands of certificates across more than a dozen brands. That depth is why the top of this list is tight: the leaders are separated by fractions of a point, and the gaps come from test history and batch consistency rather than one bad result.

Disclosure: Heavy Hitters is a supporter of this index (details). Supporters get no say in rankings: every brand on this page is scored by the same published formula, and nothing here is placed by hand.

The strongest products, by measured THC

181 vape products from 5 brands qualify for this list in New York.

A product counts here when it has at least 3 finished batches with a printed THC percentage and has never failed a test. Mean THC is the average across those batches; the range shows the lowest and highest batch, so a product that swings is visible. Strength is not quality: a stronger vape is not a better one for every person, and this page is not dosing guidance.

How we ranked

Each brand's score is the index's published consistency score (methodology), run over only that brand's finished vapes in this market: testing depth, how long the record runs, pass rate, batch-to-batch THC variation within each product line, pesticide panel breadth, public certificate links, and recall history. Because it uses one category, the number can differ from the overall score on a brand page. Population: 1,966 finished vapes with laboratory certificates in this index. A brand needs 10 to be ranked. Limits: this ranks what the index holds, not every brand on shelves; a brand that is not indexed is not ranked, which says nothing about its quality.
