Kava
Kava
Kava is a drug made from the ground roots of the plant Piper methysticum, a member of the pepper family that also includes black pepper. It is a native plant found in the South Pacific.
Kava can be taken as a drink or as a supplement or extract. Traditionally the root is crushed, ground or powdered and soaked in
water
to be drunk as a tea. This tea is often consumed socially and as part of traditional ceremonies and cultural practices throughout the South Pacific Islands.
In small doses, the effects of kava include muscle relaxation,
sleepiness
and feelings of wellbeing. However, long-term use of kava can lead to a range of health problems, including malnutrition,
weight loss
and apathy.
Australian laws and kava imports
From 1 December 2021 kava can be imported into Australia for commercial purposes with no limit on quantity.
People aged over 18 years entering Australia can bring in up to four kilograms of kava in their accompanied baggage (although local restrictions mean that kava cannot be brought into the Northern Territory).
The Commonwealth Government will monitor and evaluate the relaxing of laws for importing kava for two years, commencing 1 December 2021.

Kava – effects on the body
The active chemicals in kava are known as kavalactones. Variations in growing conditions (such as soil type and the amount of sunlight and water available) and different varieties of plant mean that the strength of kavalactones can vary widely.
The strength of a dose of kava also depends on how the drink is prepared and how much powdered kava is added to the water.
Kava is a central nervous system depressant. Even though there is no alcohol in kava, it can produce similar symptoms to drunkenness, including difficulty with balance, and slurred speech.
The effects of kava on your body can depend on:
your body size
your general health
if you have taken kava before
the strength and amount taken
if you are taking other drugs at the same time.
Common effects include:
for small doses – relaxed muscles, sleepiness, feelings of wellbeing and relaxation, mild loss of feeling in the throat and mouth, appetite loss
for larger doses – dilated pupils, reddened eyes, nausea, drowsiness, reduced muscle control (ataxia).
Kava is dangerous for some people
It’s dangerous to take kava in combination with other psychoactive drugs or alcohol. There is little information on how kava interacts with other medication, so it’s best to avoid kava if you are taking any prescription medicine.
Do not take kava if you:
are
pregnant
are
breastfeeding
are driving or operating heavy machinery
are currently taking pharmaceutical medicine
drink large quantities of
alcohol
have a pre-existing heart, lung or liver condition.
Children should not take kava.
Problems from long-term use of kava
In the long term, kava use may cause a wide range of problems including:
breathing difficulties
visual changes, including sensitivity to light (photophobia)
slight alterations to blood cells, including white and red blood cells, and platelets
liver damage
compromised immune function
kidney damage
contact
dermatitis
– causing scaly, flaky rash on the skin
appetite loss, leading to malnutrition and weight loss
loss of drive and motivation
worsened symptoms of pre-existing mental illnesses such as
schizophrenia
.
Kava withdrawal risk is low
There is no evidence to suggest people who regularly drink large doses of kava become dependent. Because of this there doesn’t seem to be a risk of withdrawal if a person suddenly stops taking kava. However, medical supervision is recommended.
Medicinal uses of kava
In 2003, products containing kava were banned in most European countries, because of concerns about its possible toxic effects on the liver. In Australia, all products containing kava were temporarily withdrawn, following the death of one person from liver failure.
This restriction was withdrawn after a review by the
Therapeutic Goods Administration in
2005

. As a result of that review, products with standardised amounts of kava, such as in supplements and teabags, became available in Australia.
Products with kava can be used for
stress
,
anxiety
and
insomnia
. If you are thinking about taking kava for medicinal purposes, be sure to contact a healthcare professional first.
