Jack Herer – CBD Vape Cartridge

The Legend, Refined in Full-Spectrum Form

Jack Herer is one of the most studied and respected strains in cannabis history named after the activist and author whose work shaped the hemp movement before most people knew what hemp was. For decades it set the standard for what a clear-headed, uplifting sativa experience should feel like: mentally sharp, creatively engaged, and grounded without being sedated.

This is that strain rebuilt for the hemp world using JustKana’s full-spectrum CO₂ extraction process. Each pull opens with crisp pine and bright citrus, followed by subtle spice and a clean earth finish. The unmistakable Jack Herer terpene signature  naturally preserved through low-temperature extraction, not stripped out and added back in from a synthetic source.

Why Choose JustKana Full-Spectrum Cartridges

• True Full-Spectrum Formula: CBD, CBG, CBC, CBN,
• Authentic Jack Herer Terpene Signature: Pine, bright citrus, spice, and earth  naturally preserved through low-temperature extraction.
• Low-Temperature CO₂ Extraction: No solvents. No thinning agents. No synthetic additives. Our CO₂ process runs at controlled low temperatures to protect the heat-sensitive terpenes and minor cannabinoids that give Jack Herer its characteristic clarity and lift. What’s in the plant ends up in the cartridge.
• Zero Fillers: No PG. No PEG. No VG. No MCT oil. The ingredient list is concentrated full-spectrum hemp oil and natural terpenes. That’s it.

Hardware Built for the Jack Herer Terpene Profile

Jack Herer’s terpene signature is one of the most distinctive in hemp and one of the most sensitive to heat. Terpinolene, the dominant terpene driving its pine and citrus top notes, degrades quickly at high temperatures. That’s why we use a ceramic core heating element.

Ceramic heats evenly at lower voltages, protecting the terpene profile with each draw rather than burning through it. The result is consistent vapor and authentic flavor from the first pull to the last.

Ceramic Core: Even, controlled heating that preserves the full Jack Herer terpene expression pull after pull.

High-Grade Glass Housing: Zero plastic contact. Zero off-flavors. Complete oil stability from fill to final draw.

1ml Capacity: A full gram of CO₂-extracted full-spectrum hemp oil.

Universal 510-Thread: Compatible with any standard 510-thread battery  button-activated or draw-activated.

How to Use

1. Attach the cartridge to any 510-compatible battery (button-activated or draw-activated).

2. Begin with a slow 3–4 second draw. Jack Herer’s full-spectrum terpene profile comes through at moderate inhalation  long forced pulls burn through the oil faster and can mute the flavor. Let it come to you.

3. Wait 10–15 minutes before taking a second draw, especially if this is your first time with this cartridge. The onset is fast, but the full effect builds over the first few minutes. Starting slow lets you find your range.

4. Store upright at room temperature, away from direct heat and sunlight. Terpenes degrade faster when exposed to heat  proper storage keeps the Jack Herer profile intact through the life of the cartridge.

Important Notes

Drug Test Warning:
Our CBD cartridges are tested to less than 0.3% Total THC however, full-spectrum products contain trace cannabinoids including THC, which can accumulate in body fat over time and may trigger a positive result on a drug screening even from trace amounts. If you are subject to employment drug testing we would not recommend using full spectrum products we’d rather you know this upfront than be caught off guard.

Air Gaps in the Cartridge:
After shipping or extended storage, you may notice what looks like an unfilled gap or air pocket in the tank. This is normal and does not mean the cartridge is short-filled. The oil settles and migrates into the coil area over time, making the tank appear less full than it is. The complete 1ml of oil is still in the cartridge. To redistribute the oil, store the cartridge upright at room temperature for a few minutes before use.

Grown, Extracted & Crafted in the USA

Every JustKana cartridge starts with organically cultivated hemp from Oregon and Colorado, extracted in small batches for precision, purity, and potency. CO₂ extraction keeps the natural terpene and cannabinoid structure intact, creating a vape that’s true to the Jack Herer legacy uplifting, authentic, and clean.
