What it is
Cannabis (also called weed, marijuana, pot, or dope) comes from the cannabis plant. Its main psychoactive ingredient is THC, which produces the "high". Another compound, CBD, is not intoxicating. The strength of cannabis varies a lot, and many modern products are far higher in THC than in the past. In Australia, recreational cannabis is illegal in most places, while medicinal cannabis is only legal with a prescription.
How it affects you
Cannabis is usually smoked or eaten. Its effects depend on the person, the amount, and the strength. Eaten ("edible") cannabis can take longer to take effect, which sometimes leads people to take too much.
- Common effects: relaxation, talkativeness, altered sense of time, increased appetite.
- It impairs short-term memory, concentration, coordination, and reaction time.
- Higher doses can cause anxiety, panic, paranoia, nausea, or confusion.
Why it can be addictive
Not everyone who uses cannabis becomes dependent, but regular use can lead to cannabis use disorder, where a person finds it hard to cut down despite wanting to. Stopping after heavy use can bring withdrawal symptoms such as irritability, sleep problems, vivid dreams, reduced appetite, restlessness, and cravings.
The risks
- Driving or operating machinery while affected is dangerous and illegal.
- Smoking cannabis can irritate and damage the lungs and airways.
- Frequent use, especially starting young, is linked to problems with memory, motivation, and learning while the brain is still developing.
- In people who are vulnerable, heavy or high-THC use is associated with a higher risk of anxiety, depression, and psychosis.
Signs it may be a problem
- Using more often or in larger amounts than intended.
- Needing it to relax, sleep, or get through the day.
- Cannabis getting in the way of school, work, money, or relationships.
