The Evolution of THC Carts: From Inception to Present Day

In 2003, the Chinese pharmacist Hon Lik invented a device that would become the first modern spray pen, which included a battery, a cartridge to hold the solution or concentrate and an atomizer. This was the beginning of the evolution of THC carts, which have undergone major changes since their debut in the legal cannabis markets. The first type of vape cartridge I found was a plastic container with a plastic wick. This product was aesthetically appealing, but internally it had some flaws.

The extracts were cut with PG (propylene glycol), a vaporizing agent that was used to improve viscosity and create larger clouds. However, this oil normally gave users a headache after the first few tears. Additionally, the plastic cartridge and the wick contributed to an unpleasant vaping experience. Unfortunately, children can mistakenly consume this sweet with THC, which causes unintentional poisoning. Shortly after first testing a vapor cartridge preloaded with THC, Gilbert's design, which included a flavor cartridge, a heating mechanism, a mouthpiece and a long, thin shape, undoubtedly paved the way for all subsequent vaping designs.

This design was never officially released to the market, but it set the stage for future innovations. Cannabis oil cartridges have come a long way since their inception. Nowadays, producers and processors are looking for the perfect synthesis between the quality of the oil and the construction of the cartridges. Some companies are closer to reality than others, but just as Pax promoted the design of cartridges by changing it, it is clear that the future of cartridges is still being invented. National and state data from patient reports show that e-cigarettes or vaping products that contain THC, especially those from informal sources, online vendors, and the illicit market, are related to most EVALI cases. The most common cannabinoids found in this study were delta9-tetrahydrocannabinol (delta9-THC) (12 samples), cannabinol (CBN) (12 samples), cannabicitran (CBT) (12 samples), cannabigerol (CBG) (11 samples), tetrahydrocannabivarin (THCV) (11 samples), Cannabichromene (CBC) (10 samples), (6aR, 9R) -Delta 10-THC (7 samples) and Cannabifuran (5 samples).

Delta10-THC ((6aR, 9R) -delta10-THC, (6aR,9s) -delta10-THC) have no pharmacological effects and 9 (R) -delta6a,10a-THC and 9 (S) -delta6a,10a-THC have very low or very limited psychoactivity. The main terpenes found in each vaping oil cartridge sample were delta9-THC and the main additives in the liquid, vapor and aerosol of the vaping oil. It consists of an atomizer as a heating element, a wick, a battery power supply and a cartridge or tank container. Finding the perfect balance between quality materials, the viscosity and composition of the oil, and the ideal temperature is key for producers and processors. A standardized tanker truck would also allow concentrate manufacturers to focus on creating excellent oil without worrying about whether or not it will work with the cartridge design or materials. The fight for a perfect cartridge continues to revolve around finding this balance. THC is fat-soluble, meaning that it must be dissolved in fats such as butter for the body to absorb it properly and produce the desired effect.

As technology continues to evolve so does our understanding of how to best use THC carts for maximum efficiency.
