Guidelines

The responsible consumption of Cannabis is mainly a health issue. People make their own choices. It’s not the purpose of these guidelines to tell people how to behave, but to ensure they have solid evidence available so they can make educated and informed decisions.

These new guidelines will help people to make those decisions.

The form of Cannabis use with the lowest health, social, legal and economic risk is abstinence. Even so, more than 2 million Australians choose to use Cannabis every year, and accept some degree of risk. Australians can reduce their health, social, legal and economic risks by following these guidelines.

Guidelines

1. Moderation

It is recommended that social Cannabis users only consume Cannabis for five days a week or less, trying to keep at least two days each week Cannabis free. (This is not applicable for people using Cannabis as a medication, e.g. relieving nausea from cancer chemotherapy) The effect from eating cookies lasts much longer. Users may only require one biscuit per day. Smokers should not require more than 4 joints per day.

2. Recognising harms that may arise

Cannabis is illegal. Possession or use can lead to arrest and a criminal record, loss of job or even worse. Be discrete. Don’t carry more than the ‘caution’ amount (NSW 15 grams). If Cannabis is seriously affecting your life in important areas such as relationships, parenting, job or finances, then seriously consider reducing or stopping.

3. Young People

Encourage young people who are likely to experiment to delay consuming Cannabis until their body and mind have matured as any drug use can affect physical and/or cognitive development. Impress on young people the need for moderation and responsibility. Avoid smoking in the presence of children. Do not smoke in confined areas with children or non-smokers present. “Passive smoking” is not confined to nicotine. Be aware that as an adult you are always a role model.

4. Potency and Contaminants

The strength of different Cannabis strains may vary widely. If you are going to use a new batch of Cannabis, only try a small amount first. When purchasing any form of Cannabis there is no certainty regarding fertiliser, fungicide, or insecticide use, how it is grown, or what affect that might have on health outcomes. Under prohibition without standards or quality control or regulation, the only way to be certain how a Cannabis plant is grown is to watch it grow.

5. Pregnancy

Women who are pregnant, breast feeding or might soon become pregnant should refrain from using Cannabis. If they still choose to use Cannabis, they should minimise their quantity and frequency of use.

6. Driving

Do not drive a car or operate heavy machinery if impaired by Cannabis. To make sure you are safe, allow at least a few hours before your last use of Cannabis and driving. If you have used alcohol and Cannabis, allow twice as long.

7. Mental Health

If you have ever had a serious mental illness, or you have a family history of serious mental illness, it might be better to avoid Cannabis and all other mood altering drugs. If you still want to use Cannabis, use as little as you can. Always have someone with you when you smoke to make sure you keep to your limits.

8. Tobacco

It is better for your health not to mix tobacco with Cannabis. Nicotine is addictive. Smoking with tobacco will often lead to you using more Cannabis by virtue of the nicotine addiction.

9. Smoke harms lungs

Consuming Cannabis by inhaling the vapour from a vaporiser or eating foods made with Cannabis are both less damaging to lungs than inhaling Cannabis smoke, but the results of eating Cannabis are less predictable. Cookies can be stronger and last longer than smoking.

10. Smoking Implements

Avoid using plastic bottles, rubber hoses, PVC, aluminium or foil to smoke Cannabis – these all give off toxic fumes when hot (you run fewer health risks with a pipe made from glass, steel or brass.)

11. Sharing

When you share joints, pipes or bongs you can also share germs and infections. Individual joints, pipes or bongs are preferable. Clean bongs or pipes after use.

12. The environment

Make sure that you discard any smoking implements, waste, or roaches carefully and responsibly. Don’t start a fire through carelessness. Left over organic waste should go into compost.
