Does anyone know if and how dangerous it is to inhale carbon fiber? how more dangerous in the heat and is it as bad as asbestos? i don't work around it i just have carbon fiber stickers on the inside of my car that could be inhaled on a daily basis.

Inhaling carbon fiber particles can irritate the lungs causing coughing and when exposed to high levels over many years it can cause black lung from being lodged to deep in your lungs it can also lead to microscopic splinters in the skin, nasal passages, throat, and lungs.

exercising at a moderate intensity, and slowly increasing the duration.
