There are several ways to vape, and the most cost-effective method will depend on an individual’s usage and preferences. Here are some options that are known to be more cost-effective than others:

1. Reusable Vaping Devices: Reusable vaping devices, such as vape pens and mods, can be more cost-effective in the long run as they allow users to purchase e-liquid refills rather than buying disposable devices.
2. Opting for a lower wattage device: Lower wattage devices use less power and consume less e-liquid, which can be cost-effective in the long run. These devices are also known for producing a less intense vapor, which can make them more efficient for those who prefer a more subtle vaping experience.
3. Using refillable tanks: Some devices come with refillable tanks, which can be filled with e-liquid, this way can be cost-effective as it eliminates the need to purchase pre-filled cartridges.
4. Buying in bulk: Buying e-liquid in bulk can save money in the long run, as it is typically cheaper to buy a large bottle of e-liquid than to purchase several smaller bottles.
5. Selecting the appropriate nicotine strength: Selecting the appropriate nicotine strength can also help to save money, as using a higher nicotine strength can reduce the amount of e-liquid used.

It’s important to note that, while these options can be more cost-effective, they may require a bit more effort and a bit more knowledge of vaping to get the most out of it.
