With Indica dominating (55%) over Sativa (45%) in this weed, you would expect a calm, serene feeling with balanced energy in the background. This is why beginners are surprised with the focused, productive high that hits them in the beginning. That’s how the Jack Flash strain got its name - it hits your body like a flash of lightning. Yes; the relaxing effects will soon calm to balance out the energizing hit. But with an average THC level of 18% and mild CBD concentration of 1%, it’s not the best marijuana strain for beginners.

Jack Flash originates from the Original Haze (an energizing Sativa) and Super Skunk (an Indica-dominant weed with calming effects). Django, the child of Jack Flash and Blueberry, is faster to deliver the relaxing effect.

Jack Flash cannabis strain has an earthy, citrusy aroma that reflects in its taste. It’s pleasant to consume, so beginners might get carried away. The good thing is that it might offer relief from mild pains and suppress nausea. However, over-consumption will easily lead to a state of panic and heavy headaches afterwards.

Jack Flash Strain Cannabinoids

THC Tetrahydrocannabinol, or THC, is a major cannabis chemical compound. It is a psychoactive element that stimulates dopamine release and induces euphoria or happiness. THC-rich strains may be helpful with such conditions as lack of appetite, chronic pains , etc. It is considered to be the primary active marijuana component. 19.6 - 21.6%
CBD Cannabidiol, or CBD, is a major compound in cannabis, which is non-psychoactive. It is also proved to counteract the side effects of the second major component THC. CBD is widely used for medicinal purposes in rubs, oils and so on. It is helpful in muscle pain cases, may treat arthritis and migraines. Even Greeks used it against pain, while Queen Victoria applied it to get rid of menstrual cramps. 0.47 - 0.79%
CBC Cannabichromene, or CBC, is a minor cannabinoid, meaning that its quantity in cannabis is quite little. Though it has the same origin as CBD and THC, it is different in functions. Without any psychoactive effects, it is an efficient cannabis compound in combating acne and depression. CBC produces analgesic, antibacterial and anti-inflammatory effects. 0.12 - 0.5%
CBG Cannabigerol, or CBG, is one of the minor cannabis compounds in adult plants. On the other hand, young ones contain a lot of this antibacterial and anti-inflammatory component. During the growth, CBG is converted into different cannabinoids, mostly THC and CBD. The compound itself increases appetite and decreases eye pressure. 0.1 - 1.06%
CBN Cannabinol, or CBN, is a trace element in cannabis that is considered to be mildly psychoactive. It appears from oxidation THC, exposed to light and heat. CBN is mostly contained in old cannabis and in traditional hashish. It is effective against insomnia, bacterial infections and appetite loss. 0.26 - 0.3%
THCV Tetrahydrocannabivarin, or THC-V, is a compound contained in cannabis in trace amounts. Even though it is close to THC molecularly, it is different in effects.

Was going all well until I started experiencing anxiety and migraines after it wore off. I tried reduced the dose but it didnt help so I had to take a break. I liked the calming effect it had on me but the negative effects were way more. This one is not for me.
