Mixing marijuana with other drugs
It can be dangerous to mix marijuana with other drugs such as alcohol or other drugs prescribed by doctors. This is because the effects of marijuana can become stronger.

There is no evidence that marijuana automatically leads to the use of other drugs.

Marijuana and pregnancy
It is not wise to use any drugs during pregnancy. THC passes from the mother to the baby through the placenta. There is some evidence that women who smoke marijuana may give birth to smaller babies. Other studies show that new born babies may have trouble sleeping.

Marijuana and the law
Using marijuana is illegal in Australia. If you use, sell or give marijuana to someone else and get caught, you could face substantial fines and penalties including a prison sentence. This also includes items used to take marijuana such as bongs. However, each state or territory has different laws regarding penalties and criminal conviction. In South Australia and the ACT for example, the personal use of small amounts of marijuana has been decriminilised. In NSW, first time offenders caught carrying a small amount of marijuana may be issued with a formal caution.

Marijuana and driving
Marijuana makes it more difficult to drive safely, especially when it is taken with alcohol. A breathalyser test cannot detect if you have used marijuana. If a police officer suspects marijuana, or other drugs, then you can be arrested and taken to a hospital for a blood and urine test. This will show whether there is THC or any other drug in your body.

It is illegal for anyone to drive while under the influence of any drugs, including marijuana. If you break this law you could lose your licence for a set time, or be fined or sent to prison.

Anyone under the influence of marijuana, who kills or injures another person while driving a motor vehicle, can be sentenced to a term in prison.

Dependence
Physical dependency on marijuana can develop. This means that you may experience withdrawal symptoms if you stop or suddenly cut down. Marijuana withdrawal symptoms usually consist of flu-like symptoms such as:

• headaches
• nausea
• irritation
• depression
