Your Care Instructions

During your examination, traces of marijuana were found in your body.

The active chemical in marijuana is THC. THC usually can be found in urine for a few days after marijuana is used. If the use is heavy, THC may be found for weeks after the use has stopped.

Possession and use of marijuana is a crime in Canada, unless it is authorized by a doctor as a medical treatment.

Most schools and employers have strict rules about illegal drug use at school or while you are on the job. A positive drug test might cause you to be expelled from school. Or it might cause you to lose a job or keep you from getting hired.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Think carefully about whether using marijuana is worth the risks.
  • Do not drive or operate heavy equipment while using marijuana. Using marijuana may affect your judgment and coordination. And it can increase your risk of being in a car crash.
  • Make sure you understand the laws in your area.
  • Know the policies of your school or your employer.

When should you call for help?

Watch closely for changes in your health, and contact your doctor or nurse call line if you think you have a problem with marijuana use.
