How to Tell if Someone Is High on Heroin

Tell Tale Signs That Someone Is High on Heroin

The drug known as heroin is highly addictive and has both strong mind-altering effects and negative health effects associated with use. Often while actively high on a significant dose of heroin, an individual will be unconscious. Still, if they are taking a lower amount or only maintaining enough in their system to put off withdrawal, they will display: 

• constricted pupils
• shallow breathing
• “nodding” as they fight drowsiness
• droopy facial expressions
