Where to find Critical Jack: stores by market
Critical Jack flower is hard to find in the US. On Oct 3, 2026, Weedmaps showed Critical Jack flower at 2 store listings in 1 of 27 US markets, all within 50 miles of Detroit; the other 26 markets, including Los Angeles, Denver and New York, had none.1 No market had an item sold as an exact eighth, so no price can be quoted. In Europe the strain travels as seeds rather than flower: Dinafem’s catalogue is online but not for sale, Silent Seeds in Rotterdam and Delicious Seeds in Valencia list their versions.2,3,4
Buy only from licensed stores where cannabis is legal for you, and only if you are of legal age (21+ for adult-use in the US). Live listings near you: Critical Jack on Weedmaps.

Snapshot of Weedmaps listings on Oct 3, 2026; one city per state, 50-mile radius, same state only. "Exact" medians use items sold as an eighth (3.5 g).1

How these numbers were collected
- Source: Weedmaps’ public product listings, captured on Oct 3, 2026 for one city per state, counting stores and deliveries within 50 miles and in the same state.1
- A menu item counts when its name contains "Critical Jack" as a whole phrase and it is sold as flower; explicit crosses and blends, names that denote a different strain and mis-filed non-flower items such as pre-rolls are excluded.
- "Median eighth" uses only items sold as an eighth (3.5 g). Listed prices may or may not include tax, deals are not applied, and medians from a handful of items are indicative only.
- Only stores with a Weedmaps menu are counted, so a low count can reflect Weedmaps coverage rather than the market.
- Disclosure: Official Cannabis’s founder co-founded Weedmaps and remains a shareholder.
Names you will see on menus
Leafly lists "Critical Jack Herer" as another name for Critical Jack, but Delicious Seeds sells a different cross under that name, so a label with "Herer" in it may be either strain.5,6 In state lab records, 14 results under near-miss names, 12 of them flower, led by "Nature's Critical Jack #3" (10 results) and 3 products labelled "Critical Jack Herer"; both are left out of our counts.7 "Critical Jack Auto" and "Critical Jack Autoflowering" are autoflowering lines that Dinafem and Delicious Seeds bred from other parents.8,9
A West Coast reputation to check against the data
Wikileaf says Critical Jack is "now widely popular throughout California and much of the West Coast".10 On Oct 3, 2026, no store within 50 miles of Los Angeles, Seattle and Portland listed it on Weedmaps.1 Our lab dataset holds no California test under the exact name; its eight tests come from Massachusetts (4) and Michigan (4).7 Germany, where cannabis is a prescription medicine, is covered in the pharmacy section above.
