"Piff" (also known as Uptown Haze, Church, or Cuban Black Haze) is a legendary, mostly Sativa, East Coast cannabis strain that gained massive popularity in the 1990s and early 2000s, particularly in New York City. It is renowned for its distinct, intense incense-like aroma and energetic, uplifting effects. 
Key Characteristics
Aroma & Flavor: The strain is famous for a "church" smell—a pungent mix of frankincense, sandalwood, lemon zest, and pepper.
Effects: Users typically report an instant, "rocketing" cerebral high that is energetic, creative, and euphoric. It is often described as an all-day smoke.
Appearance: The buds are typically airy and light, with a traditional, old-school Haze structure.
Lineage: Piff is heavily Haze-dominant, with roots believed to be connected to Purple Haze and other Haze-y phenotypes from the 2000s.
