The number of hits you can get from a 300mg vape pen depends on several factors, including the size of each hit, the efficiency of the vape pen, the user’s inhalation style, and the voltage or wattage settings of the pen. Additionally, the concentration of 300mg usually refers to the amount of CBD or THC in the e-liquid, which might not directly correlate to the number of hits.

Here’s a rough estimation:


300mg typically refers to the amount of CBD or THC in the entire cartridge or container of e-liquid. It’s not necessarily an indicator of how many hits you’ll get. You need to know the capacity of the cartridge or tank to estimate the number of hits more accurately.

Inhalation Size:

The size of each hit can greatly vary. Some people take small, quick puffs, while others take longer, deeper inhales.

Vape Pen Efficiency:

Different vape pens have different efficiency levels in terms of vapor production and e-liquid consumption. Some pens might produce more vapor with each hit, while others might use up e-liquid faster.

Voltage/Wattage Settings:

Higher voltage or wattage settings can produce more vapor, but they might also use up e-liquid faster.

Personal Usage Style:

Your individual vaping habits will influence how quickly you go through e-liquid. Some people vape continuously, while others take occasional puffs.

How Many Hits In A 300mg Vape Pen

Given these variables, it’s challenging to provide an exact number of hits for a 300mg vape pen. If you know the capacity of your cartridge or tank, you can divide the total amount of CBD or THC (300mg) by the amount of e-liquid your device holds. This will give you a rough estimate of how much CBD or THC is in each hit. However, even then, the actual number of hits you get can still vary based on the factors mentioned above.


It’s important to use vape products responsibly and to be mindful of the concentration of CBD or THC you’re consuming. If you’re new to vaping or using CBD/THC products, consider starting with a low dose and gradually increasing as needed while paying attention to any potential effects. If you have specific questions about a particular product, it’s a good idea to consult the manufacturer’s instructions or contact their customer support for more accurate information.
