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 or distillate. 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.
Warning: Keep in mind that the type of “THC oil” used in weed pens is formulated for vaping, unlike cannabis oil tinctures which are not. THC and CBD oil tinctures are typically oil-based, which makes them unsuitable for inhalation.
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:
- Oil vape pens are designed for cannabis oil and distillate cartridges.
- To avoid having your session interrupted, charge before use.
- The higher the milliamp rating (more mAh), the more battery life the vape pen has.
- If the device has adjustable power, turn it down to its lowest setting and adjust up from there.
- Replace the cartridge as soon as the flavor and performance drop off to avoid wasting your oil. (Scroll down to learn how to fill and extract THC oil.)
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 fill a weed pen
To fill your THC oil pen, all you’ll need is a syringe containing cannabis oil and an empty THC oil cart. Go slow. Let each layer settle before adding more oil, you don’t want to risk losing any of it! Here are some helpful tips to keep in mind.
- Slowly inject the oil while making a circular motion with the syringe.
- Never inject oil down the central chimney of the cartridge.
- Fill the cartridge enough to cover the wicking holes located on the outside of the coil housing.
- Let the cartridge sit at least 30 minutes after filling. The high viscosity of the oil needs a fair amount of time to soak into the wick.
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.
- Remove the cartridge from the battery to prevent oil from leaking into the battery section.
- Detach the mouthpiece—some are threaded and some will just pop off.
- For very thick oils and distillates, you may want to gently warm the cartridge up to make the oil easier to transfer, but do not overheat it!
- Make sure you have a syringe with a tip that you can fit inside the cartridge. Different style carts may require different sized tips.
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.
- Defective cartridge, usually due to a bad coil, leaking, or clogging.
- Not enough oil in cartridge to reach the wick.
- Transferring oil to a different cartridge.
- Using THC oil for dabbing or with another device.
