In 2019, Moose Labs published a report where they analyzed the amounts of harmful bacteria on shared pipes during social events. The groups were split into two. One group was given silicon mouthpieces, and the other group nothing. With an ATP monitoring system, the pipes were swabbed regularly in both groups. The results were astonishing. Where no precautions were taken, the bacteria levels were excessive. It almost had one and a half times more bacteria than a public toilet seat. Researchers said it was difficult to find a neutral object in daily life that was as contaminated as a cannabis pipe.
