In recent years, vaping has become popular as an alternative to smoking. People are curious about how vaping affects their ability to taste flavors. Let's explore how vaping can change the way we taste things. Before we talk about vaping and taste sensitivity, let's understand how our taste buds work. Taste sensitivity is all about how well we can taste different flavors. Taste buds on our tongue and in our mouth help us detect five main tastes: sweet, sour, salty, bitter, and umami. When we vape, the e-liquids we use contain a substance called propylene glycol (PG) that can temporarily reduce our ability to taste flavors. The heat from vaping can also damage our taste receptors, making it harder for us to taste things properly.
