The first thing to understand about different vapes is that there are two main categories of vapes.
Nicotine vapes: handheld devices powered by lithium-ion batteries designed to mimic the sensation of smoking without combustion. Nicotine options are customizable from 0% up to 5%, with flavors ranging from tobacco to desserts to unflavored.
Cannabis/CBD vapes: portable battery-powered or larger desktop devices powered either by batteries or electrical power supplies that heat the material. These devices are used with CBD, THC, or other botanicals, from dry herb to concentrates.
There are other substances that people vape. Like various herbs and vitamins; some daring souls choose to even vaporize coffee. Many of those products and activities are on the fringes, but the devices used are no different from nicotine or cannabis vapes—they're just different substances that happen to "work" in the devices.
There's overlapping between cannabis and nicotine vapes, like the classic vape pen which functions in both realms. Which may explain why it's the most popular type of vape in existence.
While all nicotine vapes can be called "e-cigarettes", that term is most commonly used for small devices that look similar to a cigarette in size and shape. But nicotine vapes don't stop there.
These are the smallest and simplest vapes you'll find. Open the pack and they're ready for immediate use. Once you're finished, you dispose of the device and use another. These are ideal devices for travel or for the busiest among us without the time to tinker with little gadgets. E-cigarettes work great with high nicotine in providing a satisfying hit, which makes them work well for smokers looking for a quick entry into vaping.
Pod vapes are some of the most practical vaping devices available. A pod vape is usually a two-piece device, similar to an e-cigarette, with one piece being the battery and the other a replaceable and often refillable pod. Pod vapes are usually affordable and very easy to use while performing at a higher level than most traditional e-cigarettes. They are also a perfect fit for nicotine salt e-liquid, making them a very efficient vape for nicotine delivery.
