What are the possible side effects of medical cannabis treatment?

Cannabis can cause side effects in some people, but each person may react differently. 
Mild to moderate side effects may include: 

• Anxiety 
• Nausea 
• Dry mouth 
• Sleepiness or drowsiness 
• Unusual tiredness 
• Headache 
• Confusion 
• Dizziness 
• Paranoia 
• Euphoria** 

NOTE 

**Cannabis can cause euphoria, which, depending on your medical needs, may or may not be a desired effect. Talk to your healthcare professional if you find euphoria bothersome. 
Start low and go slow. 
You should adjust your dose of cannabis until you find what works best for you. Start at a very low dose and increase it slowly. If you experience side effects, they can usually be managed by changing your dose, class of cannabis, manner of using cannabis, or strain.
