Article from HIV.gov
According to HIV.gov, "Using drugs affects your brain, alters your judgment, and lowers your inhibitions. When you’re high, you may be more likely to make poor decisions that put you at risk for getting or transmitting HIV, such as having sex without a condom, have a hard time using a condom the right way every time you have sex, have more sexual partners, or use other drugs. These behaviors can increase your risk of exposure to HIV and other sexually transmitted diseases. Or, if you have HIV, they can increase your risk of spreading HIV to others."
This article lists some commonly used substances and their link to HIV risk, and explains how you can prevent getting or transmitting HIV from injection drug use.
