Our field carries Valken brand paintballs. According to an article titled: What IS A Paintball & Is It Eco Friendly posted on Valken.com, no paintballs are NOT poison. In fact, paintballs are NOT actually filled with paint. Paintballs are actually filled with coloring and polyethylene glycol or PEG. PEG is found in toothpaste and is used in cough syrup. Does this mean you should eat paintballs? No, but having splatter on your face and getting a taste of it in your mouth isn’t that bad. Although it may taste terrible.
