The tar that is released when you smoke weed period is more dangerous then whatever you're talking about. You are getting the tar (a proven carcinogen) in much larger amounts relative to some small percentage of the ingredients in the paper that you say are harmful.

Sure, people say the THC fights cancer and negates the tar and all that... yeah, yeah. Common sense and your body's natural reaction to when you first inhale smoke (cough) should tell you smoking is bad for you.

If your gonna smoke weed regularly, there is no point to worrying about the health effects of your papers! You've got bigger things to worry about.

Lesson to take from this? Vaporize... it tastes good, and even feels good instead of making you cough. Enjoy!
