Earlier this summer we began testing the potency of cannabis flowers from various Amsterdam Coffeeshops. We’ve analyzed THC & CBD potency of buds from coffeeshop menus at The Bushdocter, Popeye, De Kade, or Original Dampkring. Now we venture to Coffeeshop Blackstar to inspect potency levels of cannabis flowers.

All testing is done using Purpl Purpl Pro by Purpl Scientific. This device allows for instant cannabinoid potency in the palm of your hand. Curious how it works? Check out our step-by-step product demo.

PITAYA – 26% TOTAL THC

BLACKSTAR HAZE – 18% TOTAL THC

DIAMOND HAZE – 26% TOTAL THC
