Because of COVID-19, everyone has become a lot more germ conscious. Hopefully, this positive trend has already extended into the world of cannabis equipment and supply maintenance. Stale, stagnant water sitting in a bong bowl is a breeding ground for bacteria, fungus, viruses and yeast. Smoking a bowl “filtered” through the equivalent of pond scum can transport all sorts of nasty pathogens into your mouth and lungs. Some contaminants can cause mild dizziness or fatigue, and others could expose you to extremely serious illnesses including Hepatitis A, pneumonia and strep throat.
The important thing to remember about cleaning your bong (and other smoking equipment) is to do it regularly. It doesn’t take long for microbes to latch on to stagnant water and start reproducing. Ideally, you’ll want to completely clean your bong after the last time you use it each day.
The accompanying resource goes into more detail about the malicious microbes floating around in a dirty bong, and more importantly, explains how to clean that bong to reduce the threat and enjoy pot the way nature intended.
