Wrong , piff is a a haze that use to float around in ny around the same time sour did , I’ve also heard people call it uptown haze , church bud , or black haze but I never heard it mistaken with purple haze . Eventually all good weed that would float around in the upper east coast, people would start calling it piff but originally piff was that uptown ny haze that was floating around , I can still taste it in my mouth when I think about it , two strains that have always been in my top 5 ecsd and original piff
