Nicotine withdrawal symptoms

What causes withdrawal symptoms

Nicotine is the addictive drug in tobacco. It causes the brain to release a chemical called dopamine, which makes you feel good. Over time, your brain starts to link that good feeling with smoking.

When you stop smoking, your brain has to adjust to not having nicotine anymore. This change is what causes withdrawal symptoms. These effects – plus cravings – can make it tempting to start smoking again.

Using quitting aids like nicotine replacement therapy (NRT) or prescribed medication, along with support from a Quitline counsellor or your doctor, can help make things easier.

Common withdrawal symptoms

Most withdrawal symptoms go away within two weeks. Some people feel better even sooner. Here are some common symptoms:

• Strong cravings to smoke or vape
• Feeling irritable, frustrated or angry
• Feeling nervous or anxious
• Feeling sad or low in mood
• Difficulty focusing or thinking clearly
• Feeling tired or low on energy
• Trouble sleeping or waking up during the night
• Constipation

Some people also notice:

• Increased coughing
• Dizziness
• Vivid dreams or nightmares
• Mouth ulcers

How to manage withdrawal

Withdrawal can be tough, but it doesn’t last forever. Most symptoms ease after the first few days. Try these ideas to cope:

• Keep your hands and mind busy with distractions like games or puzzles
• Change up your routines to break habits linked with smoking
• Use NRT or medication as recommended by your doctor
• Talk to a Quitline counsellor or someone you trust

Each day without smoking is a win. Keep reminding yourself why you’re quitting and take it one step at a time.
