Originating in California, P-91 is a 50/50 hybrid born from Afghani crossed with Northern Lights, a Thai-derived lineage that threads its heritage through the cultivar’s roots. Its potency is underscored by a THC level around 22 percent, and it is widely regarded as a grade A- strain by many users. The name commemorates Poway in San Diego, where this variety first emerged in 1991, anchoring its story to a precise place and moment in cannabis history.
Slightly leaning toward Sativa in its balance, P-91 can deliver a brisk psychoactive onset that some users experience as a swift, energizing lift, while others note occasional deeper psychoactivity. The scent is mellow, with woody and earthy notes, and the flavor blends diesel, citrus and earthiness, leaving a strong, resinous aftertaste that lingers on the tongue and palate.
Medically, it is favored for chronic pain relief—including stubborn backache—and can also ease insomnia, nausea, appetite loss, anxiety, and related fatigue. On the safety side, it is regarded as a generally safe option, though dry mouth and dry eyes are common side effects after consumption.
