Concerns with paraffin's carcinogenic properties

I started fire breathing a couple weeks ago and I've been using mostly vodka and other powders. Powders of course aren't the best just because of their feeling in your mouth, and vodka works well but isn't very practical. The most commonly used fuel seems to be paraffin, but even before I started this I knew paraffin was known to be carcinogenic. While having it sit in my mouth, and all those deep breaths I take before I spray it out, I just have a suspicion that it could easily give me some type of cancer. I was wondering if there was any other alternative that's less dangerous but equally effective?
