Smoking is always bad for health, no matter what tool you are using to smoke,
Many things are happening when utilizing a bong, or smaller bubbler, while consuming cannabis. Burning cannabis produces a huge amount of smoke stream that contains all the things you dont want, and a lot of the things you don’t, such as hot smoke, polycyclic aromatic hydrocarbons (PAHs), hundreds of carcinogenic compounds generally referred to as tar, and fine particulate matter, like ash.
some prefer use it along with ice cube cooling, each inhalation, the water (or other liquid) inside the bong filters out the ash that would otherwise end up in your mouth, such as when smoking a joint or pipe. There’s also a certain amount of tar that is filtered out of each inhale as well, which is why bong water eventually turns a color to brown after certain time of uses.
research conducted in California have shown that bongs filter more water-soluble psychotropic phytocannabinoids than tar and fluorocarbons, which means the user has to smoke more cannabis to get to where they want it, because the tar:phytocannabinoid ratio is now more skewed towards tar. The amount of research on the effectiveness of bongs and bubblers is very low, and as such, an air of speculation and debate surrounds the effectiveness of these tools. A.famous Researcher for the LA-based medical cannabis company Terra Tech, states that the amount of phytocannabinoids lost in the water of a bong is negligible, and that many phytocannabinoids and terpenes found within cannabis have nearly zero water solubility. This is why cannabis concentrate-makers use nonpolar solvents like CO2 to extract phytocannabinoids from plant matter, instead of traditional water.
The main focus for many folks to using bongs or other glass smoking tool is their ability to cool and filter the smoke through water, offering a smoother draw even with larger hits. Bongs tend to maintain the aromas and tastes of the strain as well, and the lower amounts of tar and ash you’re inhaling in general, the better.
over all there is not really any good for smoking throughout a bong or just plain cigarette.
