Jack Flash is an indica-dominant hybrid (sativa/indica ration of 60:40) with THC levels reaching as high as 20%. That makes this a very potent strain for patients seeking a body high with psychedelic effects and a euphoric boost. This plant, which won the Dutch High Life Cup in 1998, is a hybrid of the sativa Jack Herer, the indica Super Skunk, and Haze, itself a sativa. It’s best known for the speed of the high, which hits almost instantly, a result of this strain’s Jack Herer genetics. While THC levels are high, CBD levels are something of a mystery: This definitely isn’t recommended as a CBD strain, but the exact percentage of CBD is unknown. Jack Flash smells of earth and citrus and has a sweet flavor. The high is multi-faceted, with deep body relaxation, euphoria, energy, and creativity, along with a strong happy feeling. It provides relief to patients suffering from anxiety, depression, and bipolar disorder. It’s also good for ADHD, anorexia nervosa, and migraines. Negative effects are limited to a relatively slim possibility of dry mouth or dry eyes. Dizziness is possible but unlikely. This strain may be hard to find outside the American West, but it’s fairly popular in California and Colorado.
