The Alaskan Thunder (ATF for short) strain originates from the Matanuska Valley in Alaska and its Sativa genetics are somewhat of a mystery. Being a Sativa, this strain really only affects your head and is a popular choice of medication for medical marijuana patients suffering from chronic migraines, PTSD, sleep disorders, and more.
The Alaskan Thunder strain is known for its ability to create a soaring, cerebral head-high. It can definitely take your mind for a ride, so you may want to start with low quantities (1-2 puffs) if you are a first-time patient who is afraid of experiencing any sort of paranoia.
Alaskan Thunder should be considered a morning or day-time Sativa due to its peaceful, uplifting nature. This strain always makes me feel more talkative than normal, and even more intellectual at times, due to its deep, thought-inducing high.
