  • Description

    C Jack, tis famous for its sweet Jack-Skunk flavor and for winning the Cannabis Cup in 2013. C Jack is a hybrid cannabis that has been around for quite some time and has gained popularity in recent years. This is because the C Jack strain has been specially bred to increase the THC content to make it more potent.

    C-Jack’s parent strains are a cross between the sativa dominant Jack Herer strain and the hybrid Skunk #1 strain. Jack Herer is responsible for creativity and focus, while Skunk #1 accounts for the sweet smell. The result is a jack-skunk strain that energizes rather than sedates, making it great for morning use.

    The sterling reputation of the Jack Herer strain genetics has made our ASCND C Jack among the most sought-after cannabis cartridges available. C Jack is a favorite for recreational smokers because it boosts mood, stimulates creativity, and produces euphoria. The C Jack sativa-leaning hybrid delivers its psychoactive effects immediately to elevate your cannabis experience.

    Kurvana’s C Jack is available in 0.5 mL and 1 mL cartridges, which you can purchase online or through our trusted retail partners. The C Jack strain price ranges from $40 to $65 and is part of our ASCND line, which offers maximized THC levels in every vape.

    • Beta-caryophyllene: This terpene is said to have anti-inflammatory effects, and some users claim that it provides pain relief and helps them manage their depression symptoms. It is found naturally in basil, black pepper, and oregano.

  • Extraction

    The purity of Kurvana cannabis oils is preserved through proprietary and unadulterated extraction methods.
    Our extraction process excludes chemical solvents, thereby ensuring both purity and safety. The specific chemical profile of C Jack is extracted as-is, preserving the natural essence of the strain, and allowing vapers to experience the richness of our stimulating ASCND C Jack oil.

    Additives commonly blended into other brands, such as vitamin E acetate, propylene glycol, vegetable glycerin, artificial flavoring, synthetic terpenes, fillers, and thinners, are never used in any Kurvana products.

  • Ingredients

    The C Jack strain contains a unique fingerprint composition of cannabis oil and cannabis-derived terpenes. The cannabis concentrate is a composite blend of cannabinoids: tetrahydrocannabinol (THC), and extremely low concentrations of cannabidiol (CBD), with a predominating THC content.
    The terpenes in cannabis oil contribute to each strain’s unique aroma, flavor and effects. They work in tandem with the cannabinoid content in each strain to enrich the vape experience, by imparting different psychoactive influences. They also have an entourage effect, which means they work synergistically with THC in the Jack Herer x Skunk #1 hybrid to produce the desired euphoric and creative effects.
