How is heroine used?

There are four ways to take heroin; one is to break it out into lines and snort it, another is to smoke it by putting it on tin foil, lighting it from underneath while you have a tube in your mouth from 1-2 inches above the heroin, and when lit, the smoke can be inhaled; another way is to inject it which is not as easy as it sounds, and is also the most popular way to ingest heroin; and last is to eat it which is the least popular because of how ineffective it is.
