The distinction between gravity bongs, vaping, and smoking lies in the way plant extracts are transformed into inhalable compounds. Smoking entails combustion, whereas vaping does not.
The combustion process during smoking leads to the generation of potentially harmful compounds. On the other hand, vaping does not involve this combustion.
While both methods require combustion to convert the plant material into inhalable smoke, gravity bongs produce smoke in a more regulated environment due to their enclosed setup. This containment helps prevent the escape of material and ensures a controlled smoking experience.
