Your mod could affect your vape juice’s flavor, but only in a couple of ways. If you use a sub-ohm vape, your clouds will be huge and flavorful. Other, lower-powered vapes will not give you the same results. On the other hand, a dirty vape mod can make your vape juice taste gross. It’s important to clean the vape regularly to keep a consistent taste and to keep your vape in good condition. If you feel like you’re not getting the most out of your vape juice, try steeping it. That will bring out more flavors.
