OXBAR vapes, like all vaping products, are generally designed for adult use and should be used responsibly. While they may be a safer alternative to traditional cigarettes due to the absence of combustion, they still contain nicotine, which is addictive. Daily use depends on individual tolerance and health considerations. It's important to stay informed about the ingredients, ensure proper usage, and be mindful of any potential effects. If you have health concerns, consulting a medical professional is always a good idea.
