Is smoking lavender or in general less harmful if done while drinking tea?

There is no evidence that smoking lavender or any other substance while drinking tea is less harmful. Smoking, regardless of the substance, can have various negative health effects, including respiratory issues and an increased risk of chronic diseases such as cancer. Drinking tea, on the other hand, can provide some health benefits due to the presence of antioxidants and other beneficial compounds, but these benefits are not related to smoking any substances.
