2. Cannabis

Marijuana consists of dried flowers and leaves of the cannabis plant and may be smoked or eaten
in food. It is the most commonly used illicit drug in Australia. Marijuana is also known as 'grass',
'mull', 'weed', 'dope' and 'ganja'. Marijuana, hashish and hashish oil come from this plant.
Tetrahydrocannabinol (THC) is the major psychoactive compound that gives the user a 'high' and
affects the mood and perception of the user. Hashish is made from the resin of the cannabis plant.
Hashish is stronger than marijuana and is usually mixed with tobacco for smoking.
Hashish oil is a liquid extract and is the most potent cannabis product. It is usually added to 'joints'
(cigarettes) or cooked in food and eaten.
As with alcohol, the effects of cannabis will vary from person to person depending on:
• individual weight and height, general health, mental health and vulnerability to mental health
problems and mood;
• the way in which the cannabis is taken or ingested;
• the amount or concentration of cannabis taken;
• whether the drug is mixed with other drugs; and
• the experience and regularity of use.
Cannabis use promotes a feeling of well being and relaxation in the majority of users. Somebody
impaired by cannabis may exhibit:
• signs of tiredness;
• difficulty in concentration;
• lack of interest;
• poor coordination;
• confusion;
• clumsiness;
• glazed eyes;
• impaired judgement; and
• slowed reaction times.

Cannabis consumption may lead to psychological dependence and paranoia.
When mixed with alcohol, there is an increased risk of accidents.
Somebody who is vulnerable to mental health problems is at increased risk of experiencing mental
health problems if they use cannabis.
Cannabis use can cause respiratory problems and make pre-existing problems worse.
