How is heroin most commonly consumed?

Heroin is most commonly consumed through injection, which allows for quicker and more intense effects compared to other methods. When injected, heroin enters the bloodstream almost immediately, providing an intense euphoric experience that users often seek. This method can also increase the risk of overdose due to the rapid onset of effects.

While heroin can also be smoked, swallowed, or snorted, these methods generally result in a slower onset of effects and a less intense high. Smoking and snorting may appeal to users who are concerned about the health risks associated with injecting, but the prevalence of injection use highlights it as the most common method among heroin users.
