Side Effects

Medicinal cannabis and cannabis-based medicine are characterised by few and harmless side effects. Most patients experience no side effects when using cannabis.

The most frequent side effects are dizziness, dry mouth and fatigue. Mood swings and euphoria are rare. If you are already taking medicine that affects your liver function, it is important that your liver count is monitored regularly. When combined with other medicine, cannabis use could potentially further affect your liver.

The long-term effects from using medicinal cannabis and cannabis-based medicine have not been fully established. When used regularly, 10 – 20% are likely to develop a psychological addiction to medicinal cannabis and cannabis-based medicine. In comparison, 20 – 50% of patients who are treated with morphine-based drugs become addicted. With regular intake of alcohol the risk of addiction is 15%, and with nicotine and cocaine the percentage is 30 – 50%.
