How Long Does Heroin Stay In Your System

Heroin is a dangerous and highly addictive synthetic opioid drug that is made from morphine. It is sold in powder form and as a less expensive, sticky black substance known as black tar heroin. Heroin is usually injected, but it can also be smoked or snorted, resulting in a fast-acting,  powerful high. Some people combine heroin with cocaine, which is also known as speedballing. Heroin binds to opioid receptors in the brain which results in a dopamine release, giving the user temporary relief from chronic pain and anxiety. The intense feelings of pleasure combined with the almost immediate high heroin produces makes it a highly addictive drug that can lead to physical or psychological dependence after just one use.
