What's in bong water?
Bongs are among the least harmful ways to use cannabis. Water acts as a natural filter and cools the smoke, with a more pleasant experience and smoke containing only trace amounts of particles such as tar and other combustion residues.
But since water acts as a smoke filter, what’s in the water in a bong? What’s hiding in there, and why is it important to keep a bong clean and change the water frequently?
Substances in the water used for a bong
Although some of the substances found in bong water are toxic, others, such as cannabinoids are less effective. Water does not discriminate in what it filters out, so it retains some of the cannabinoids that will not be absorbed. In addition, plant material can settle in the water in the bong, resulting in lower concentrations of cannabinoids in the smoke.
The water in a bong, like any standing water, can also harbor all kinds of bacteria and fungi. Yeast and other microorganisms can also grow in dirty bong water. Drinking bong water is strongly discouraged, and it’s not even recommended for watering plants. It may also contain toxic levels of mold.
How often should you change the water in a bong?
Ideally, the water should be changed after each use, particularly to remove any potentially carcinogenic substances released by the filtration system. If the water isn’t changed often enough, the bong will also be difficult to clean. Some bangs with specific shapes may promote the accumulation of material
You’ll know it’s time to change the water when a layer called biofilm forms on the surface. Forming on the surface of the water, biofilm can harbor a variety of harmful pathogens, from streptococci to E. coli. When inhaled, these substances can cause serious illnesses.
One of the benefits of bongs is that they filter out harmful substances, but they can only do so with clean water.
Alternatives to water in a bong
If there is several possible bong options, when it comes to the liquid, the options are more limited. Water can be replaced with just about anything you can drink, though there are some bad ideas out there. Regardless of the liquid, ice cubes or very cold water can cool the vapor even further.
Unsweetened cranberry juice is a popular alternative to water in Canada. Although the juice doesn’t drastically change the flavor of a bong, it does give it an attractive color. Better yet, the natural acidity of cranberry juice can help keep the bong cleaner for longer.
Sparkling water instead of still water is another option. The fizzy bubbles can add lightness and texture to your bang, as well as a subtle flavor if the sparkling water is flavored with citrus or lime.
For a slight variation, you can add a few strips of lemon zest to the water. Mint leaves can also add a touch of freshness!
Sweetened fruit juices are not recommended. The sugars can leave a sticky residue, making the process of cleaning the bong very frustrating. Similarly, alcoholic beverages can release dangerous alcohol vapors.
