If your favorite nicotine liquid (e-liquid) flavor doesn’t taste the same and your electric cigarette gives you a weak throat hit, you might have developed some tolerance to the flavor. That’s why using at least three nicotine flavors is a good practice.
My first nicotine liquid, very high on nicotine, felt as though I smoked a conventional cigarette—taste was strong and felt good, and the throat hit hit as hard as it should. I liked it so much that I wanted to smoke only that flavor.
But by the time I finished half the 30ml bottle, the taste and throat hit started to feel weak. After alternating my favorite flavor with another for two weeks, my favorite flavor felt as good as when I first tasted it.
And remember that when your electric cigarette tastes too light, tolerance to your favorite nicotine liquid flavor can be only one of the reasons. Always charge the batteries, clean the atomizer, and use fresh and properly-stored nicotine liquid.
