What is a THC oil vape pen?

A weed pen, or THC oil pen is a relatively simple, two-part electronic device used to vaporize THC oil, delta 8 THC carts and other cannabis distillates. An evolution of early vape pens, weed vape pens are most often shaped like writing pens—hence the name. Sometimes they are referred to as a cartridge battery. That's because every weed pen houses a small battery that heats your oil in an atomizer cartridge containing a wick and a heating coil. This heating process turns concentrates into THC-filled vapor.

Voila! With the press of a button and a drag on the mouthpiece, high times are on demand. The odor is faint and dissipates quickly, so THC pens are the most convenient way to fly high while cruising under the radar. Keep reading to find out how to use a pen with your own THC oils and cartridges.

Tips for getting started

The first thing you’ll need is a THC pen and some THC oil or distillate. Cannabis oil is generally sold in prefilled cartridges, but can be made or purchased separately for refilling your own carts—which is more cost-effective but requires a bit more work. Ideally, you want THC oil that comes preloaded into a syringe.

There are two ways to use a marijuana vape pen. If you have a prefilled cartridge, you simply screw it onto the pen and press the button. If you buy a kit that includes an empty cart, you’ll want to fill it with your oil or distillate—more on that later. Here are a few key pointers for getting started with your THC oil pen:

How to clean a THC oil vape pen

Since THC vape pens are two-part designs, with the cartridge being disposable, there’s not much cleaning necessary. The most important thing to keep clean is the connection. Typically, cannabis pens have a 510-connection— that’s the threading that connects to the cartridge that contains the oil. That connection should remain relatively clean to keep the current flowing. THC oil is thick, but a little seepage can find its way in the connection. Left uncleaned, the device may stop working.

Cleaning the vape pen’s 510 connection is simple: just use a Q-tip and high-strength isopropyl, and wipe until clean. Cleaning the thread will not make a noticeable difference in the vape experience, but it will help prolong the lifespan of the device. While you are at it, make sure you clean the mouthpiece and 510 threads of your oil cartridge too.

How to remove THC oil from cartridge

To extract the oil from your cannabis pen, you will need an empty oil cart and a filling syringe with a blunt tip that fits inside your oil cartridge. You may need to slightly warm up the cartridge, to allow the oil to flow better when extracting it.

When should you remove THC oil from your cartridge?

Sometimes weed vape pens can fail, usually when the coil becomes the weakest link. Fortunately, you can transfer the oil to another device. Here are some of the most common reasons you may need to extract the oil from your cartridge.
