Withdrawal: what to expect and how long it lasts

When you stop, your body notices the missing nicotine. According to Health Canada, withdrawal symptoms usually start within one to two days, are strongest in the first week, and last about two to four weeks. Some people notice them for longer.

Common symptoms: restlessness, irritability, anger or sadness, trouble concentrating, coughing, trouble sleeping, and sometimes constipation in the first weeks.

What helps:

If you feel sad or low and it doesn’t lift after a few weeks, see a health care professional.
