Boost 1:1 Vape Cartridges – Harlequin 1g

What a 1:1 cartridge is

This is a 1 g 510-thread vape cartridge from Boost, filled with a 1:1 blend — roughly equal parts CBD and THC. That ratio is the whole point of the product. A standard THC cartridge is THC-dominant; a 1:1 carries a comparable amount of CBD alongside it, which is why people who find high-THC carts too much often reach for a balanced ratio instead.

Harlequin

Harlequin is a sativa-leaning strain that has been grown for decades specifically because it expresses CBD as well as THC, rather than THC alone. That makes it a natural fit for a 1:1 format. Nothing here is a medical product — it is simply a different cannabinoid balance from a standard cartridge.

510 thread, and what you need to use it

510 is the near-universal screw thread for vape cartridges, so this fits almost any pen battery you already own. If you do not have one, any 510 battery works; variable-voltage batteries let you run concentrates cooler, which most people find preserves the flavour better than running them hot. Cartridges do not need charging themselves — the battery does.

Storage and handling

Store cartridges upright, at room temperature, away from direct sun. If the oil looks thick after time in a cold room, letting the cart sit upright in a warm hand for a minute is usually enough. Do not leave one in a hot car — heat thins the oil and can cause leaking around the mouthpiece.
