The buzz associated with nicotine is caused partly by the release of epinephrine, also called adrenaline.
This rush can increase heart rate, respiration and blood pressure. Feelings vary, so not everyone will experience vaping in the same way. A pleasant or relaxing sensation also does not mean the exposure is harmless. Nicotine’s immediate effects can help explain why vaping may become connected with stress, concentration, social routines or attempts to change how you feel during a difficult moment.
