Alaska Thunder Fuck—aka ATF—is a legendary strain and, according to legend, is a cross of Northern California Bagseed and Russian Ruderalis with a bit if Afghani in the mix. It certainly is a rugged, ragged-looking sativa, but maybe that’s what you’d expect to come from Alaska during the 1970s. Either way, ATF is very high in THC content. This fine example from North Seattle’s The Green Skunk was extremely strong with two-hour body-numbing effects. This strain is not especially activating by sativa standards and should probably be used in the evening by patients, as you’ll feel a bit deflated as the effect wears off. ATF is excellent for pain relief, anxiety and insomnia.
