As with all medical treatments, medicinal cannabis isn't for everyone. In Australia medicinal cannabis is not a first-line treatment for any condition. This means that doctors only use medicinal cannabis for people who have tried other medicines without success.
Medicinal cannabis is not safe for people who have a personal or family history of certain mental health conditions, such as schizophrenia
If You Are Pregnant or Breastfeeding
Typically, women who are pregnant or are planning to become pregnant will be advised by their doctor not use medicinal cannabis.
In addition, cannabis can pass into a woman’s breast milk at high concentrations.
Driving and Operating Machinery
People who use medicinal cannabis, especially with THC present can experience dizziness, fatigue and concentration problems as side effects. This makes it difficult to carry out skilled tasks and can impair judgement. People who need to drive or operate dangerous machinery should not take medicinal cannabis with THC.
Hypersensitivity
A small number of people are hypersensitive to cannabis or other ingredients in medicinal cannabis products. These people should avoid using medicinal cannabis as it can cause a severe allergic reaction.
