There are a few potential reasons why people may turn to vaping or smoking when they are stressed:

1. Habit: For some people, smoking or vaping may be a deeply ingrained habit that they turn to automatically when they are feeling stressed.

2. Short-term stress relief: Some people may find that smoking or vaping helps to reduce their stress levels in the short-term. This may be because the act of inhaling and exhaling can be calming, or because nicotine (a substance found in tobacco products) can have a mild sedative effect.

3. Coping mechanism: For some people, smoking or vaping may be a way to cope with stress or other negative emotions. It may provide a sense of comfort or a temporary escape from the stressor.

It's important to note that while smoking or vaping may provide short-term stress relief, these behaviors are not healthy or effective long-term solutions to managing stress. There are many other, healthier ways to cope with stress, such as exercising, practicing relaxation techniques, or seeking support from friends and family.
