Vaping is less harmful than smoking, but it's still not safe. E-cigarettes heat nicotine (extracted from tobacco), flavorings, and other chemicals to create an aerosol that you inhale. Regular tobacco cigarettes contain 7,000 chemicals, many of which are toxic.
But there is no safe level of tobacco consumption. The best option is always to quit smoking. All tobacco contains nicotine and other toxic chemicals. Even if you don't breathe in the smoke, you still absorb harmful chemicals through the lining of your mouth.
