If you or your friends use opiates such as heroin, it's really important to know about Naloxone.

Naloxone is drug that is used to reverse the effects of opioids such as heroin, morphine, methadone, fentanyl and oxycontin.

It's sometimes also known by it's brand name, Narcan. If someone has overdosed on heroin or another opiate, an injection of Naloxone will reverse the overdose – the person will wake up/become concious again. It doesn’t have any effect if no opiates are in a person’s system, and it also has no effect on other drugs such as benzos, alcohol or ice.

It’s important to know that Naloxone is only active in the body for about 1-2 hours, which means the risk of overdosing on opiates like heroin especially if a person uses again after waking.
