This presumably sarcastic homage to the Bush-era security firm is actually highly useful as medicine, with applications in treating anxiety, low mood, migraines and other headaches, muscle spasms, nerve pain, and chronic bodily pain.
Blackwater isn't especially popular among those who have tried it, but tests suggest a relatively high concentration of THC, topping at least 20%. Consistent CBD numbers are harder to come by, but that medical cannabinoid apparently makes up much less than 1% of this strain, which means Blackwater isn't recommended for seizures.
This strain is overwhelmingly indica, with a sativa/indica ratio of about 10:90, which explains the intensely physical effects. It's the offspring of the legendary Mendocino Purps and San Fernando Valley OG, a sativa-dominant hybrid.
Blackwater has a smell of sweet berries and an earthy flavor. The body high is deeply relaxing, with intense euphoria, psychoactive effects, couch-lock, sleepiness, and strong hunger. Negative effects aren't widely reported with this strain but probably include dry eyes and cottonmouth.
Blackwater sells best in Colorado, the Pacific Northwest, and Arizona, though it may also come around on other legal markets as well as the black market.
