Heroin (Smack, Junk)
Heroin is a white or brown powder or a black, sticky goo. People can mix heroin with water and inject it (shoot up) with a needle. They can also smoke it or snort it up the nose. Heroin is a type of opioid, which means it is similar to the pain medicines that come from the poppy plant.
Heroin can cause a rush of good feelings just after it’s taken. Some people throw up or feel itchy after taking it. Some people may want to sleep and their heart rate and breathing can slow down. When the drug wears off, they may feel a strong urge to take more.
