Heroin is a white or brown powder or black glue. It is an opioid drug made from morphine, a natural substance found in the seeds of the Asian poppy tree. It can be mixed with water and injected with a needle. Heroin can also be smoked or snorted through the nose. These forms of heroin use are transmitted to the brain very quickly. 

This means that it slows down a person’s brain function and affects their breathing. Heart rate may be irregular. Ambulance officers, family, and friends can prescribe naloxone to counteract the effects of heroin. In February 2016, it was reprogrammed so that naloxone was available for purchase without a prescription. Talk to your pharmacist for more information.
