How does nicotine make you feel?

Using tobacco does not produce strong effects like alcohol or other drugs, but it can cause a lightheaded sensation that some people find pleasant. It can also make people feel relaxed, happy or giddy and gives a small adrenaline rush. If someone uses nicotine often, they can develop tolerance and will need to use more to get the same effect. They may also feel stronger cravings and urges.

People often use nicotine products- particularly smoking or vaping at the same time as other drugs and may find they want to use  more when drinking alcohol or smoking cannabis.

Some of these effects pertain to nicotine alone, whilst others relate to smoking or vaping nicotine products specifically. 

A Reddit user talks about their experience with smoking cigarettes:

“Most people begin smoking together as teenagers and begin to associate positive experiences with smoking cigarettes. I personally loved smoking and inhaling the smoke and blowing it out. It smells horrible though to most people and it messes up your lungs.”

How can you be safer when using nicotine?

Nicotine causes the most physical damage when in a tobacco product, especially if it is used often. It is always a good idea to consider the things you can do to be safer if you are using nicotine products. 

Try using less tobacco products 
Tobacco causes the most physical damage when people who use it regularly over a long period of time. If you smoke daily, even cutting down a small amount can reduce some of these effects. If you smoke less often or socially, consider trying to put limits on when you smoke and how much to cut down on your use.

Avoid mixing cannabis and tobacco.
If you are smoking cannabis, try to avoid mixing it with tobacco (spliff, spin or chop) as the nicotine in tobacco can make it more addictive. If you are using both, consider alternating between them instead of using at the same time. 

Consider switching to Nicotine Replacement Therapy instead of smoking 
Some people believe that switching from smoking tobacco to chewing it or smoking in a pipe can make it safer. However, the harm from tobacco use is very similar no matter how you use. Instead, you may want to consider using nicotine replacement therapy (NRT) such as patches, gums or lozenges. NRT delivers nicotine to your body which can help reduce the cravings for tobacco and make it easier to cut down on how much you use. 

Consider vaping to help you quit smoking
Vapes  can contain nicotine and are sometimes used to help people stop smoking. If you are vaping, consider choosing closed-system vapes (like vape pens) as they tend to have fewer negative effects because they do not have to clean the coils and you can't mix potentially harmful substances into the liquid. There are many vapes available in New Zealand, and they are all different. There is support to help you make decisions about vaping on the Vaping Facts website.

What happens if you have too much nicotine?

Unlike alcohol or other drugs, nicotine won't cause a bad trip. In rare cases, you can develop nicotine poisoning from using too much. 

Here are some things that may occur if you use too much too quickly, use for a long time or get nicotine poisoning:

If you smoke tobacco you might have a cough, feel irritable or agitated, have a sore throat or headaches, feel dizzy, faint, tired, breathless or nauseous.


  • Focus on breathing – try taking slow, deep breaths.
  • If you are able, call and talk to somebody you trust and ask them to help keep you calm.
  • Do not use more tobacco, caffeine, alcohol or other drugs, as these can make you feel worse.
  • Move to somewhere quiet – try to sit or lie down and do something relaxing.
  • Drink water to stay hydrated.

If you have an ongoing or severe cough, have a sore or tight chest, vomit, feel severely tired or your asthma gets worse, call a doctor or Healthline (0800 611 116). You may be developing problems from smoking such as inflammation of the airways (bronchitis). They can talk you through the next steps.

If you experience severe hearing and vision changes, vomit severely, experience chest pain, have difficulty breathing, have severe heart palpitations or an irregular heartbeat or lose consciousness, call 111.

What do comedowns from nicotine feel like, and how can you feel better?

Nicotine does not have 'comedowns' in the same way that other drugs like MDMA do. However, if you use often, you may feel unwell when the effects of nicotine start to wear off. 

If you:

  • Have cravings for nicotine
  • Have difficulty concentrating or thinking
  • Feel irritable or agitated
  • Feel restless or unsettled
  • Have difficulty sleeping
  • Feel anxious
  • Feel dizzy or faint

Then try:

  • Get plenty of rest and sleep
  • Remember to eat and drink plenty of water
  • Get moving to release feel-good brain chemicals
  • Reach out and talk with friends and whānau for support
  • Relax and do things that you enjoy to take your mind off not feeling well
  • Avoid caffeine, alcohol and other drugs
  • Practise mindfulness and deep breathing, and try writing down your thoughts and feelings

What are the long-term effects of using nicotine?

Depending on how you use nicotine, the long term effects can be more or less severe. Nicotine alone, in the form of patches, gums or lozenges, or through vaping can have long term effects, but these are much less severe than those from using tobacco products/smoking cigarettes. 

Many of the effects below pertain to long term us of tobacco . Half of all long-term smokers will die from a disease related to smoking.  Secondhand smoke can also lead to developing some of the conditions listed.


  • Decreased hunger
  • Early ageing and skin wrinkles
  • Changes in weight
  • Yellow fingers and nails
  • Yellow eyes
  • Yellow teeth
  • Irregular menstruation (women)
  • Slow healing of wounds
  • Back pain
  • Chronic coughing


  • Anxiety and irritability
  • Mouth sores
  • Worsening asthma symptoms
  • Fungal infections
  • High blood pressure
  • Erectile dysfunction
  • Inflammation of airways and chronic bronchitis
  • Early menopause (women)
  • Hearing loss
  • Lowered fertility
  • Cataracts in eyes
  • Osteoporosis
  • Cognitive impairment
  • Miscarriages


  • Reduced blood flow around the body (can result in gangrene and damage to parts of the body especially skin, fingers, toes and limbs)
  • Emphysema
  • Diabetes complications
  • Blood clots
  • Mouth and throat cancers
  • Bladder cancer
  • Stomach cancer
  • Heart issues (attacks, artery blockages, disease)
  • Cervical cancer
  • Lung cancer and lung diseases
  • Strokes
  • Blood and bone cancer

Smoking can affect your baby if you smoke while pregnant. It can cause miscarriages, premature (early) birth, low birth weight, birth defects of the mouth and lip and increased risk of SUDI (sudden unexplained death in infancy) after birth. It is not recommended to smoke while pregnant or around your baby.

Chewing tobacco, snuff (snorting tobacco) and vape (heat not burn) products carry different risks. Chewing tobacco and snuff make you more likely to develop diseases of the mouth and nose. Smokeless tobacco products may have slightly lower risks than smoked tobacco. However, all forms of tobacco carry a high risk of harm to your body.

A Reddit user talks about their experience of quitting smoking:

“My sinuses sometimes start hurting as-well as a headache in general (comes and goes), it also feels like there is a drip at the back of my throat? Not sure how to explain it, sort of like I’m hacking up mucus or something? I’ve become a lot more irritated and feel quite on edge (bouncing my leg up and down etc).”

How can nicotine affect your daily life?

Although nicotine is addictive, it is not likely to have major impacts on how you function in your daily life. Unlike alcohol or other drugs, your ability to work, drive or do tasks using your hands (fine motor skills) are not likely to be impaired. If you have used lots of nicotine in a short period of time, it may make you feel nauseous or dizzy. If this happens, try to take a break before returning to work or other activities.

Over a long period, it may affect your ability to work and interact with others. Some of these changes may be more noticeable than others. You may find yourself having cravings throughout the day or wanting to leave to smoke or vape. 

If you smoke nicotine will it show up on a drug test?

Nicotine use is legal in New Zealand, including in the form of vaping or smoking.  The most common reasons someone may be tested for nicotine use is by request of a doctor or by an insurance company. If it is tested for, nicotine can be detected for 3–4 days in urine or 1–10 days in blood.

A potential employer or landlord can ask if you smoke cigarettes or vape and can refuse to give you a job or rent a house based on this. This is not considered discrimination under the Human Rights Act. Smoking is also allowed to be banned in a workplace, bar, hospital or prison.
