Afghan Hash Plant, Northern Lights, and Dutch Skunk all joined forces to create White Ice, a potent indica-dominant hybrid (exact sativa/indica ratio unknown).
This strain is very popular among the patients who have tried it, but they're few and far between. Aside from its sweet smell and dense white crystals, not much is known about the flavors or appearance of White Ice. The same goes for its effects, though this strain's indica leanings suggest the high is primarily physical. Like other indicas, it is probably best used late at night or on rainy days, as couch-lock is possible.
There is little available information on White Ice's medical applications. Its chemical composition is also somewhat uncertain, though some tests report THC levels as high as 20% and CBD levels below 1%. That means this strain is best used for its THC content and shouldn't be used as the only treatment of seizure disorders or other problems that are alleviated with CBD. Negative effects mostly likely include dry eyes and red eyes.
White Ice is definitely a specialty strain, so it's hard to find. But it does sell in California and possibly elsewhere in the American West.
