Is it safe to smoke orange/clementine peels?

I enjoy smoking, but I realized that it's actually not the nicotine or the taste of the tobacco that I enjoy; I just like the feeling of sitting there and puffing on a pipe. It's a nice way to relax and focus on my breathing. In light of this realization, I have decided to find something less harmful to smoke. Tonight I tried clementine peels, and I found that the smoke was very smooth (indicating low carcinogen levels?), and it tasted and smelled good. I have no interest in any sort of high or anything other than the feeling of smoking, I just wanted to check if anyone had any information on possible consequences of smoking orange or clementine peels that I am unaware of (besides the obvious carcinogens that come with smoking anything).
