Hybrid
Origin
Jack Flash is a Jack Herer backcross blended with Super Skunk and Haze, made in the Netherlands to give Jack Herer the growing traits of a Skunk. Jack Herer supplies the cerebral, psychedelic front end; the Skunk and Haze sides supply the yield and the body. It has no descendants on file. The 1998 Cup win is what put it on the map, and the fast up-to-down arc is what kept it there.

About
Jack Flash is named for how fast it turns from up to sedated.
It crosses Jack Herer with Super Skunk and Haze, and won the 1998 Dutch High Life Cup. The high starts buzzy and psychedelic, then flips to calm and heavy inside about an hour. That flip is the whole point.
The name is the arc.
What to Expect
Jack Flash opens buzzy and euphoric with a mildly psychedelic edge, then flips inside about an hour to a calm, sedated body. Leafly's reviewers lead with happy at 59 percent of a solid sample, with uplifted and euphoric readings behind and energetic at 44. The first act is social and creative; the second is the couch.
Negatives are light: dry mouth at 22 percent, dry eyes at 14, and the sharper readings near 4. The fast turn from energetic to sedated is the thing to plan around, not a side effect. It is an evening strain.
Flavor and Aroma
Jack Flash smells sweet and skunky with a spicy edge. The flavor is fresh orange and citrus with a hash-and-herb note underneath. The orange is brighter than the skunky nose suggests.
Terpenes Explained
Jack Flash has no measured terpene profile in our data, only six names: Humulene, Myrcene, Terpinolene, Caryophyllene, Linalool and Limonene.
Nothing is quantified, so the orange-and-hash flavor cannot be tied to a compound. A jar with a genuine fresh-orange lift over the skunk is the one to want.
Cannabinoids and Potency
Jack Flash THC is reported from about 16 to 20 percent, with the lab-measured sample in our data near 18, so it tests in that range. It is moderate by modern standards. CBD is a trace.
Jack Flash tests moderate but the effect changes fast, so plan for an evening where you can ride the shift from up to down.
