If you’re a new user looking to buy a vape pen, you’re probably wondering whether you want to get a pre-filled vape pen, or a vape oil pen you can fill yourself like a mod. To make this decision, it’s important to know what differentiates them. Pre-filled CBD vape pens are disposable vape pens that are ready to use right from when you buy them. If you’re on the go or traveling somewhere, then this is the perfect choice, since you don’t have to take extra oil with you or stop to fill the vape pen up. In many instances new users seek a refillable cartridge or vape device such as a vape mod in an attempt to save money. What they do not realize is that the cartridge / hardware itself is typically very inexpensive for the manufacturer and the cost of the product (the CBD oil) would not be reduced by more than a couple of dollars by selling the oil in a bottle for refilling. Disposable CBD cartridges and CBD pens are also calibrated to heat the oil at a low temperature for a smooth cool vapor that is going to keep the cannabinoids and terpenes intact, rather than burning them off. They’re great for users of all sorts, because there’s no hassle—except for the fact that you have to throw them away. Vape oil pen mods are one that you fill yourself. If you’ve used CBD drops in the past and enjoyed figuring out what dosage you prefer, then this might be a good choice for you. Most mods are going to require vape juice product (as opposed to a raw hemp oil distillate) which will be cut with VG, PEG, or PG. The reason for this is that they heat the product at a higher temperature than the disposable vape pens and cartridges. CBD oil itself cannot be heated this high without some sort of filler because it would be burned off or overheated by the mod. These fillers are not necessary for effects (other than large clouds of smoke) and typically it is ideal to avoid them for health reasons. Vape juice also can be messy to keep up with when it comes to cleaning your mod pens and swapping out the coils for new ones is a whole other story when it comes to hassle and expense. If you are buying for the first time, you can usually save money and make your life easier with a CBD oil vape pen starter kit which comes with a 510 thread battery that you can connect any cartridge to in the future.
