Anywhere you live there are people with drugs. Most people just suck at finding them. If you're addicted to heroin you have decent motivation for finding them.
Also if you aren't finding heroin around, it's pretty unlikely that you're going to get addicted to it.
It isn't like kids smoking weed where they buy a small amount to sell kids overpriced dime bags and then kids go to buy it and it's like " OMG EVERYBODY IS OUT OF WEED", because the 2 people they know that sell it are out.
