Who Jack Herer was

Wikipedia describes Jack Herer as an American cannabis-rights activist and author, identifies him as director of Help End Marijuana Prohibition, and records his two presidential campaigns.1 Sensi Seeds calls its strain a tribute to him, and Leafly and Weedmaps likewise identify him as its namesake.2,4,5

The page’s biographical information concerns the person. It does not make health, therapeutic or medical claims about a plant or any product.1

What the award record supports

Sensi Seeds’ own historical list is the source for the fuller award chronology. Its record includes later 2015, 2016 and 2017 Jack Herer placements as well as the earlier wins shown above.3

Because this is a breeder-published list, the guide attributes the full record to Sensi Seeds. Weedmaps independently repeats only the 1994 Cannabis Cup win and the 1999 first-place sativa result among the opened sources.4
