There are two strains that use this name, the other being an indica-dominant cross of White Widow and Purple Elephant. This strain, on the other hand, is a sativa-dominant cross of White Rhino and an unknown sativa.
The exact ratio of sativa to indica is unclear. THC levels are also a mystery with this strain, though there's a good deal of information about the other White Elephant. But the effects are known to be both physical and mental, with an enjoyable body buzz and an energized boost of euphoria. That makes this strain a good choice for depression, anxiety, and insomnia. It's not ideal for seizure disorders, however, as it's low in CBD, much less than 1%. White Elephant tastes of Kush, with sweet pine notes.
The smell is pungent, earthy, and spicy. There's little available data on adverse effects, but dry mouth is common in almost all strains, as are dry eyes.
The other White Elephant isn't as hard to find as this one. The West Coast is probably the best bet, though even there a search for this White Elephant will probably only lead to the other White Elephant.
