This indica-dominant strain (sativa/indica ration unknown) is almost certainly a descendant of the original OG Kush, but beyond that not much is known about its heredity. PVC OG is the private creation of Positive Vibrations Collective in Long Beach, Cal., and that's about the only place on Earth where patients are likely to find it.
The amount of THC and CBD in this strain is something of a mystery, though published reviews suggest it's relatively potent with THC.
The paucity of information about CBD contents means this strain probably shouldn't be relied upon as exclusive treatment for seizure conditions. Instead, PVC is good medication for anxiety, ADHD, muscle spasms, chronic pain, and everyday stress. The high is mostly physical, with mental clarity, a dose of euphoria, and a tingly sensation throughout the body.
This strain has an earthy, floral smell and a similar taste. The buds are purple and green with orange hairs and dense crystals.
There are few reports of adverse effects, but users can probably expect watery eyes, cottonmouth, and possibly paranoia. PVC OG is worth trying if only for its subtle take on OG Kush, but unless you live near Los Angeles, you'll have to go looking for it.
