While it's not completely proven that vaping directly causes cancer, it’s still a risky habit. Some of the chemicals in vape products are harmful and can affect your lungs over time. There have been cases of people developing lung issues or diseases from vaping, which can be serious. Although smoking cigarettes is generally worse in terms of cancer risk, vaping isn't necessarily safe. If you're using weed pens, it's important to consider the potential harm to your lungs, even though they don’t contain nicotine. Being mindful of what you're inhaling is key.
