Gunja is an illegal drug containing an ingredient called Delta-9 tetrahydrocannabinol (THC), which affects the way you think, feel and behave. It also affects your body.

Gunja is both a depressant and hallucinogen.

Depressants slow you down. This can make you feel happy and relaxed. They can also make you have no shame, feel down, angry or jealous. These drugs can be dangerous and can cause vomiting and unconsciousness. Other types of depressants include: alcohol, benzos, tranquillisers, heroin and some pain killers.

Hallucinogens can make you see and hear things that aren’t there or make things look really strange. The effects can be different each time. These drugs can be dangerous. Other types of hallucinogens include: LSD or acid, magic mushrooms, mescaline and PCP.

Gunja can be swallowed or smoked.

You can only feel the effects for a few hours but it can stay in your body for up to a month.

Short-term effects

  • Gunja can change your mood and sometimes make you laugh at anything.
  • You may see things differently and get ‘the munchies’ (really hungry).
  • It makes your heart beat faster, eyes get red, mouth gets dry and breathing deeper.
  • It slows you down, you can’t concentrate very well, and you start thinking differently.
  • Some people, when they smoke can get paranoid (fearful and suspicious), worried or restless. When someone gets paranoid they may think people are after them. Some people may see or hear things that aren’t there. This can last a few hours or more.
  • If you drive when you’re ‘stoned’ you can have an accident because your reaction time is slowed down and you can’t concentrate very well.
  • Some people have unsafe sex when they are stoned. This puts them at risk of sexually transmitted infections or an unwanted pregnancy.

Long-term effects

  • Some people feel they have to be stoned all the time and can’t live without it.
  • It can cause respiratory problems like chest infections or other health problems like cancer.
  • Gunja can make you less motivated. You can stop looking after yourself.
  • You forget things.
  • You’re more likely to get in trouble with the law because gunja is illegal and sometimes you do silly things when you’re stoned.
  • Gunja puts pressure on families. It can cost a lot of money.
  • It’s best not to use gunja.
  • Mixing drugs is dangerous. If you mix gunja and grog it can make the effect of the drugs much greater. This can make you really spin out and you may vomit or pass-out.
  • The more you use the more harm it causes.
  • Have healthy food around so you don’t eat unhealthily when stoned. If you have got the munchies make sure you leave some food for your family.
  • If your friend becomes very paranoid (suspicious and fearful) or sad when stoned, tell them these feelings will pass and try to keep them calm. 
  • Never leave them alone when they are feeling like this. If necessary get some help from a family member or health worker.
  • Getting very fearful, anxious, depressed or paranoid when you are stoned shows you that gunja is not a good drug for you and your body doesn’t like it.
  • Never drive or operate machinery while stoned.
  • You shouldn’t get stoned in dangerous places.
  • You shouldn’t use getting stoned as an excuse to break the law (which includes Aboriginal Law as well).
  • Always use a condom when having sex to prevent unwanted infections or pregnancies.
  • Think about how your gunja use could be affecting your family and community.
