This strain is anything but poison. OG Poison is a potent indica-dominant hybrid bred specifically to fight insomnia. It hits hard and fast, inducing sleep in even the most tightly wound users. The genetics aren't clear, but presumably it contains genes from both OG Kush and Durban Poison, both longtime favorites among patients. This strain has a sativa/indica ratio of roughly 30:70, so the indica side definitely wins out.
THC levels can be unusually high, with a maximum of about 22% in tests. CBD content is higher than usual, but not necessarily enough to recommend this as a treatment for seizures of other disorders that respond to that cannabinoid. Expect a focused, calming body high that may induce sleep.
That makes it a good choice for insomnia, though it's also recommended for treatment of anxiety, nausea, and headaches, including migraines.
Dry eyes and dry mouth are the most common side effects, while headaches and paranoia are more rare. OG Poison has a pungent, woody aroma with a hint of pine and a similar flavor. This strain isn't especially common or popular, but it's found most often in Los Angeles and Arizona.
