If a dependent person stops taking cannabis, they may experience withdrawal symptoms because their body has to get used to functioning without cannabis. People may experience withdrawal symptoms for less than a week, although their sleep may be affected for longer.

Some of the withdrawal symptoms that may be experienced include:

  • cravings for cannabis
  • loss of appetite and weight loss
  • irritability
  • anxiety
  • sweating
  • upset stomach
  • chills and tremors
  • increased body temperature
  • disturbed and restless sleep, often interrupted by nightmares.

Getting help


In Australia, there are many different types of treatments for drug problems. Some aim to help a person to stop using a drug, while others aim to reduce the risks and harm related to their drug use. Find out more about treatment.

What to do if you are concerned about someone’s cannabis use

If you are concerned about someone’s drug use, there is help available. Contact the alcohol and drug information service in your state or territory.

What to do in a crisis

Always call triple zero (000) if a drug overdose is known or suspected—and remember that paramedics are not obliged to involve the police.

If someone overdoses or has an adverse reaction while using cannabis, it is very important that they receive professional help as soon as possible. A quick response can save their life.
