What are Weed Pens? 

Weed pens are those slick-looking gadgets that people use to vape THC oils. Its primary purpose is to serve as a battery that powers a weed vape. Sometimes the term weed pen is used interchangeably with a weed vape. However, a weed vape is the product in its entirety, whereas a THC pen is just one of three components. The other two components are a vape cartridge and vape juice. You can usually buy a pen and have your choice of an extensive selection of pre-filled vape cartridges in Canada. Basically, the vape pen is the power source that powers an atomizer that is in the cartridge. The atomizer then heats the E juice and turns it into a vapor that can be inhaled. As previously mentioned, you can typically find a massive selection of pre-filled vape cartridges that you can attach to your pen and use immediately.

Different Types of Weed Pens

There are basically two types of weed pens. There are ones that you reuse, and there are disposable weed pens. The reusable vape pens take reusable vape cartridges. You can purchase pre-filled vape cartridges whenever you need more. Disposable vape pens have the cartridge permanently attached to the pen. The most notable advantage of a disposable THC pen is that you can use it, toss it, and buy a new one. What’s common between these two varieties is that they are easy to use and are among the most convenient products.

Common Benefits of Cannabis Pens

The most significant advantage of vape pens is that vaping is said to be cleaner than smoking. However, research still needs to be done on this topic. The advantage is that concentrates are purged of many unwanted chemicals and plant material, making for a purer product. However, it is crucial to buy your weed pens from a trusted source to ensure you are getting a high-grade product.   Another benefit of cannabis pens is that they emit little to no identifiable scent. Yes, there may be a huge puff of vapor, but it would be very difficult to know what you were vaping. This means that there are more places that you could vape, where smoking weed may not be appropriate. However, there are still restrictions on public vaping, and you typically cannot vape in most places you cannot smoke.   Furthermore, THC pens are a very convenient way to take your medicine. They are always ready to use, as long as you remember to charge the batteries.    Lastly, weed pens are said to induce increases in relaxation, happiness, euphoria, sedation, focus, creativity and overall well-being.
