When it comes to purchasing THC cartridges, it is important to make sure that they are legitimate. Authorized dispensaries have products that are all legally tested to ensure their safety. Most likely, any THC cartridge purchased illegally or even online has not been tested. To ensure that the product is legal, tested and safe to use, it should have a license number on the packaging.
If a cartridge lacks this quality test, it should be discarded immediately. Real vaping carts usually contain THC levels of 70 to 90%. Any amount less than 60% is likely to have been reduced with some type of agent, and any amount greater than 99% would also be considered suspicious. NBC News states that 100% of fake THC cars contain hydrogen cyanide along with a fungicide and a harmful source known as myclobutanil.
Myclobutanyl transforms into a highly poisonous gas when applied to heat, hence the traces of hydrogen cyanide found in counterfeit THC cartridges. To ensure that you are purchasing a legitimate THC cart, make sure that it has a license number on the packaging and that the THC levels are between 70 and 90%. If you are unsure about the legitimacy of a product, it is best to discard it and purchase from an authorized dispensary.
