Here are some things you want to keep in mine when shopping for weed oil cartridges.

Extraction method 

 The best extraction method for THC oil is currently CO2 extraction. It is also the most popular and safest method for making cannabis oil, distillate and live resin carts. The reason why it is so prevalent these days is because this THC oil doesn’t contain residual solvents like alcohol or butane. 

Thinning agents- Most THC oil cartridges contain some kind of thinning agent. This is require for the oil to maintain a consistency that is optimal for vaping. The most common thinning agents are vegetable glycerin and propylene glycol (VG and PG), which are commonly found in regular e-liquid. Some cartridges contain other fillers like PEG and more recently TEC Temper, which is a new formula derive from natural terpenes.

Potency – If you’re looking to get blast, you can’t be wasting your time with weak THC oil carts with mostly filler. For the strongest effects, you’ll need something extremely potent, preferably distillate or live resin. They contain the least amount of filler and the highest levels of THC and natural terpenes.

Terpene-specific – Terpenes are organic compounds foun in all plants that give them their individual flavor and personality. They also determine whether a cannabis strain is a hybrid, indica or sativa. Terpenes interact synergistically with other cannabinoids to create different effects. They enhance the flavor and serve as a natural filler to keep the viscosity down.

Cannabinoid-specific

 Many pre-filled cartridges contain cannabinoid-specific oils. The most common cannabinoid, other than THC, is called cannabidiol, also known as CBD. A lot of research shows that THC can actually enhance the benefits and effects of CBD oil. These cannabinoid-specific oils are generally found in various ratios like 50/50 or 80/20 THC:CBD for example. Some may incorporate other cannabinoids such as CBN or THCv which provide additional benefits beyond THC and CBD vape oil.

• Quality – If you live where cannabis is legal, you probably have access to high quality pharmaceutical grade THC oil. The products listed above have been carefully selected based on reviews and research. If you don’t select any of the brands on this page, be sure to do your own research before making your purchase. Avoid cheap oil carts high in filler with and potential residual solvents.
• Compatibility – There are two main styles of pre-filled THC cartridges. The most common is the standard 510 e-cig tank, which connects to your standard e-liquid and CBD vape pens. The other style of cartridges are called pods, which require a specific device like the PAX Era or GPen Gio for example. Make sure that you are getting the appropriate cartridge for your particular device and it coul never hurt to have a few backups on hand.
