Nicotine is a central nervous system stimulant. When inhaled, it crosses into the brain within 10-20 seconds and binds to nicotinic acetylcholine receptors, triggering release of dopamine, adrenaline and noradrenaline. The dopamine release produces a brief sense of pleasure and the adrenaline and noradrenaline increase heart rate, blood pressure and alertness. For people prone to anxiety, this stimulant effect can worsen anxiety symptoms over time, even though individual puffs feel temporarily calming.

The reason vaping feels calming in the moment for many users is the withdrawal cycle. Once a person is nicotine-dependent (which happens quickly, typically within days to weeks of regular use), the body experiences mild withdrawal between vape sessions. The withdrawal manifests as restlessness, irritability and yes, increased anxiety. When the next vape hits, those withdrawal symptoms ease, which feels like relief. The relief is from withdrawal cessation, not actual anxiety reduction. The underlying anxiety baseline is being raised by the dependency itself.

Research consistently shows that nicotine users experience higher rates of anxiety, depression and stress symptoms than non-users. A 2022 study of 3500 college students found e-cigarette users were significantly more likely to have anxiety symptoms than non-vapers. The American Heart Association has linked vaping in teens and young adults specifically to higher anxiety and depression scores. A 2014 meta-analysis showed that quitting smoking and nicotine is associated with lower anxiety, depression and stress levels long-term, plus improved mood and quality of life. The NHS mental health framework recognises this pattern.

The biochemistry of nicotine and anxiety

When nicotine binds to nicotinic acetylcholine receptors in the brain, it triggers a cascade of neurotransmitter release. Dopamine produces the brief pleasurable feeling. Glutamate increases focus and alertness. Noradrenaline raises heart rate, blood pressure and respiratory rate. For people with healthy nervous systems this is a brief stimulant pulse. For people with underlying anxiety, panic disorder or generalised anxiety disorder, the stimulant effect can trigger or worsen anxiety symptoms directly. Over weeks and months of regular use, the brain adapts by downregulating dopamine receptors, which lowers baseline mood and increases anxiety between vape sessions.

Why vaping feels calming when it actually is not

The classic “vaping calms me down” experience is the body returning to a less-stressed baseline after the withdrawal symptoms that built up between vape sessions are relieved. From the user perspective this feels identical to genuine anxiety relief. From the brain chemistry perspective, the relief is just cessation of withdrawal, and the underlying anxiety baseline is now higher than it was before nicotine dependency began. Studies asking people to compare their anxiety before and after starting to vape consistently show vapers have higher anxiety baselines than they did before, even though they describe feeling “calmer when vaping”.

What the research actually says about teen and young adult mental health

The American Heart Association published research in 2023 linking dual nicotine and THC vaping in young adults to significantly higher rates of depression, anxiety and suicidal thoughts. The CDC reports that the most common reason US middle and high school students give for vaping is “I am feeling anxious, stressed, or depressed”. A 2022 scoping review in PMC found nicotine use in adolescents causes measurable impairment in the developing brain, leading to cognitive and psychiatric issues including depression, anxiety, and substance abuse risk. UK Mental Health Foundation guidance treats nicotine dependency as a risk factor for anxiety conditions, not a treatment for them.

If you are using vaping to manage anxiety and want to stop, the NHS has specific support pathways. The most common path is through your GP, who can refer you to talking therapies and prescribe nicotine replacement options that do not have the same false-relief cycle.

If you are in mental health crisis or having thoughts of self-harm, call 999, NHS 111, or the Samaritans on 116 123 (free, 24/7). If you are vaping primarily because it feels like it helps your anxiety, that pattern itself is a signal worth talking to your GP about. The NHS does not consider nicotine an effective anxiety treatment and offers free pathways to better-evidenced support.
