Despite the long duration, this one didn’t stay at peak potency for very long, only feeling strong for 45 minutes or so , then feeling eminently functional and basically scaling down from there until it was barely noticeable at about two and a half hours. That said, the effects were great for all of us and made this a pretty perfect daytime medication no matter the activity… it would be good for creative pursuits, data entry/menial type of work, watching a movie, etc. — anything where sustained attention is desirable would be enhanced by this one. Taste and smell-wise, it pretty much brought the expected Jack Herer bag of smells and tastes, though the smell in particular was top-notch and would be the deciding factor to make us give this strain a try amongst 20 others. This is recommended as a fairly motivational and focused daytime type of med for those who don’t need serious pain relief or enduring top-level potency.

Though this sample probably wouldn’t stand out in a row of jars full of top shelf strains, it certainly belongs there judging from its coating of well-preserved trichomes and overall healthy appearance.


This strain smelled like almost every other top-notch Jack Herer or Jack hybrid (including Jack Flash) and definitely ranked among the top examples we’ve had in that vein — super fresh and “cool” lemon-pine cleaner smell with a wonderful backing floral sweetness that seemed to come out more post-grind. The post-grind smell reminded one reviewer of grenadine — very nice. It wasn’t super-pungent mostly due to its Haze nature, but did majorly increase in pungency when ground-up.


Not quite as “Jack-y” as the smell, the flavor was a little more muted, with some slightly earthy notes at times overpowering the spicy, flowery Haze flavor. The smoke was very smooth and non-expansive, making this a superb choice for patients who don’t want to cough when medicating. It burned away to a light gray ash, showing that it had received a proper flush before harvest.


This was a very cerebral Sativa, leaving one reviewer staring blankly at the TV for 15 minute stretches and the others feeling rather energetic and motivated by their tasks. The “staring blankly” review wasn’t due to couchlock or mental sedation, but rather due to the way this strain causes your attention to dial into whatever happens to interest you at the time, an almost unwavering focus. Physically, the strain started with the hallmark Sativa effects such as orbital/eye/head pressure, a slightly buzzing body, and an uptick in both mood and heart rate. There wasn’t much of a direct body effect, but we all felt capable and pain-free throughout the experience, able and willing to take on almost any task while also looking the part (very ‘stealth’ med — no outward physical effects).

Despite the long duration, this one didn't stay at peak potency for very long, only feeling strong for 45 minutes or so , then feeling eminently functional and basically scaling down from there until it was barely noticeable at about two and a half hours. That said

Fine, fabulous high and the taste is my fav of all strains. I keep some in the freezer in reserve.

This is the best weed I’ve ever smoked in more than 40 years of smoking pot. The euphoria was tremendous; nothing I smoked in all the years I’ve been smoking pot, gave me this result.

My first puff of Critical Jack left me with my eyebrows raised questioningly. I wondered if I’d actually taken in any smoke until I exhaled and a saw a ton of smoke. I tasted absolutely nothing. A couple more puffs with the same result; intriguing. I didn’t feel any immediate effect. Which is unusual for me. About ten minutes later I started feeling something, I just wasn’t sure what. Slowly but surely my energy level began to raise and my Fibro fog began to clear. I was mellow and enjoyed sitting around relaxed and deep in thought. It eased my pain, and relieved finger stiffness. Though it did irritate my sinuses slightly. I wouldn’t pay a premium for this strain but I would buy it on sale again for sure. I really enjoyed how long the effects lasted. This is a good late afternoon early evening strain for me.

Critical Jack is a sativa dominant strain (60:40 sativa/ indica ratio) and is a cross between Jack Herer and Critical Mass. Even though it does not look extraordinary, it is coated with well-preserved trichomes and offers a healthy appearance. The structure is a bit on the wispy side, but overall… ]]>
