In Islamic tradition, smoking is generally considered to be haram (forbidden), as it is harmful to one’s health and can lead to addiction. Vaping, which also involves inhaling and exhaling smoke-like vapor, is similarly discouraged and considered haram by some Islamic scholars.

Therefore, it is generally advisable for Muslims to avoid vaping during Ramadan and to adhere to the principles of the fast, which includes abstaining from all forms of smoking and vaping. It is always best to consult with a qualified Islamic scholar or religious authority if you have any questions about what is permitted during Ramadan or other aspects of Islamic practice.
