HIV doesn't discriminate between the substances that are being injected - steroid users and heroin users share the same level of risk. From an infected mother to her baby. Sharing injecting equipment may take place by accident - being stuck by a discarded needle for example. Any situation where body fluids can be exchanged carries risk - wiping up a spill of any body fluids should not be attempted without adequate protection. People who are carrying HIV infection can look and feel healthy - they may not be aware of the infection themselves.
Condoms are available free from family planning clinics.
If you use drugs and are injecting, always use a clean set of works. Remember, HIV and other infections can be passed on if you share any injecting equipment. Sex and drug use don't always mix - some drugs will inhibit erection or orgasm, others may reduce sexual interest. Some of the things you may have heard about the virus will be true, and some will be based on misinformation, myth and rumour. These immune system dysfunctions have only recently been discovered and researched, and the use of drugs, an individuals lifestyle, diet and a history of chronic infections may be just as important precursors to AIDS as sexual behaviour - if your immune system is not working properly you are less likely to be able to fight off viral infections whether they are sexually transmitted or not.
