When it comes to choosing the right THC vape cartridge, there are a few things to consider. First and foremost, it's important to select a quality brand. Fake vaping cart manufacturers are unfortunately common, so it's best to buy from an authorized dispensary to ensure you're getting the real deal. Next, check for potency and purity.
Most THC oil cartridges should contain between 70 and 90%. Look for the consistency, smell, appearance and brand name of the oil. If the oil is too liquid, it could be a heavily purged BHO or something with additives. Ideally, the oil should have a uniform and pleasant color and contain no particles or crystals.
It should also have a strong marijuana smell, rather than artificial flavors. If you can't smell the oil, it may not be properly sealed. Additionally, watch out for windows in the cartridge – this generally means that the car got hot or stayed on the shelves for too long.
