Using the fatty acid info listed here (scroll down to see it):
As with most nuts/seeds the omega-6: omega-3 ratio is pretty high (in this case ~100:1 it seems), and the overall PUFA content is also pretty high. That being said, Mark has recently posted about how nuts and seeds (and food in general) should not be treated as one nutrient that has certain properties. There are other compounds in a whole food that interact to modify how it affects health.
That being said, I think it's fine to use occasionally. If you get a mega-dose, it'd be a good idea to balance it out with some omega-3 from fish/fish oil.
