Drugs are any substances that, when taken (either by inhaling, swallowing or injecting) enter your bloodstream and change the way your body works. Some drugs are legal such as alcohol and tobacco. Others are illegal such as cannabis, cocaine and heroin. Medical cannabis is legal but only if a doctor prescribed it for you to use. Taking prescription medicines not prescribed for you is also illegal.
Drugs work on the brain and affect your ability to make safe decisions.
Any drug can be harmful. They can have short term harmful effects as well as cause long term problems especially to young people whose brains are still developing.
Even though some drugs are illegal, some people still choose to take drugs. Knowing the facts about drugs and how they might affect you can help you to make better decisions about whether to use them. It can also help to reduce any harm drugs cause you. Read more about commonly abused drugs, including their side effects and risks, and ways to be safer.
If you're worried that you might have a problem with drugs, it's a good idea to talk to your doctor about it. Your doctor has to keep all information about your medical care confidential, and is a good person to see because they know you best. But if you'd prefer to see another doctor, you can see a doctor for free at 298 Youth Health, phone (03) 943‑9298.
You can also contact the Community Youth Mental Health Service (CYMHS). CYMHS is free for youths aged 13 to 18 who may have mental health or alcohol and drug issues. The service provides short-term intervention, which includes assessment, treatment and support. It also coordinates and supports youth and their families or referrer to get longer term treatment if needed. Young people can refer themselves to the service. A GP, counsellor, teacher or parent can also refer you. This can be by phone on (03) 358‑2690 or using the online referral form. CYMHS can also provide information about other services and treatment available in the community.
