  • It is known by a variety of other names including:
    • Marijuana
    • Grass
    • Hasish (or hash)
    • Ganja
    • Pot
  • There are many active chemicals contained in cannabis
    • The main one is delta 9-tetrahydrocannabinol (THC)
  • It is a hallucinogen – this means that is can cause hallucinations
  • More commonly it makes people feel calm & relaxed
  • It can also cause anxiety, paranoia, confusion & depression

What are the different ways you can take cannabis?

  • You can smoke it, usually mixed with tobacco
    • This is known to be far more dangerous for your physical health than smoking tobacco alone
  • You can eat it
    • In a cake or a cookie
    • As a tincture or in an oil
  • You can “vape” it 
    • This technology is relatively new and the health-risks are less well-understood

Is cannabis effective as a painkiller?

  • The evidence is limited
  • The Therapeutic Goods Administration (or TGA), the government body that regulates medicines, states that:
    • cannabis should not be the “core component” for treating pain
    • Further evidence is required to determine safety & effectiveness
  • They seem doubtful that cannabis is effective for fibromyalgia and arthritis
  • They are more positive about its role in helping with pain associated with MS (Multiple Sclerosis)

Can cannabis help with Multiple Sclerosis (MS)?

  • According to the TGA:
    • Cannabis can probably help with:
      • Pain
      • Spasticity
      • Sleep
    • Cannabis probably doesn’t help with:
      • Disability and disease progression
      • Tremor and incoordination
    • Cannabis may possibly help with:
      • Quality of life
      • Bladder function
  • There have been no studies comparing cannabis to current standard MS treatments
    • This means that the current treatments may (or may not) be more effective than cannabis

Can cannabis control nausea and vomiting?

  • Yes, it can, but…
  • It has been shown to be less effective than current conventional medications
  • It should therefore only be considered when other treatments have all failed

Can cannabis control Epilepsy?

  • The evidence is poor
  • Cannabis is only recommended:
    • In patients under 25, and…
    • If other treatments have failed, and…
    • In combination with other more conventional medications
  • Seizures may also worsen

Can I get cannabis on prescription?

  • Yes, a doctor can apply for a license to become an “authorised prescriber” of cannabis- that license would be specifically for you, and only if it is appropriate for your condition and circumstances.
  • In March 2018 the Therapeutic Goods Authority (TGA) updated its guidance on prescription cannabis
  • They thoroughly assessed a variety of prescribable cannabis products, looking at the scientific evidence from 100s of studies
  • The TGA warns that:
    • There are concerns about the safety of “vaping”
    • There is a significant risk of interactions with other drugs, which are poorly understood at this time
    • The effects of long-term medicinal cannabis use are poorly understood
    • There is a high incidence of side-effects such as dizziness, nausea, diarrhoea, drowsiness, forgetfulness, mood disturbance and distractibility
    • Dosing is difficult as there are no established protocols for starting treatment
