Some people do snort heroin because they believe it is safer than injecting. It is often the preferred method by people who are more ‘casual’ heroin users. However, heroin is highly addictive and if you’re snorting it because you think it’s safer, you’re wrong. A high number of users go on to inject heroin within a year. Not only does snorting heroin damage the nasal tissues, it is absorbed into the bloodstream slower than if it were injected. As you wait for the hit to take effect you might think it hasn’t worked, and take more, and this can lead to overdose.
