Is scotch tape toxic if inhaled? I had a broken cigarette that I had taped together with scotch tape and I wasn't paying attention very well and accidentely smoked some of the tape as well. I was wondering if scotch tape is toxic if inhaled in this way.

No. I am far more concerned about the toxicity of your smoking, and the fact that your habit is so strong that you would tape a broken cigarette than i would be about effects of scotch tape vapor. There is no known toxicity of this in the low dose amount you would have inhaled. What you should be thinking about is smoking cessation, before that does some real harm.
Interesting . Interesting question. I don't think that the scotch tape that you smoked was any worse than the other chemicals and carcinogens in your cigarette.
