>I've finally quit nicotine after 5 years of vaping. After being clean for over a month, I still get random and intense cravings for nicotine. Is there any data on how long it will take before these cravings completely go away?

Great question and congratulations on quitting! Craving and other withdrawal symptoms typically peak on the 3rd day and then stay high for 3-4 weeks before starting to taper off. However, it can persist for longer periods of time. For people who experience cravings for a longer time, nicotine replacement products can help people stay quit during difficult times.
