2. Fishermen
Drug abuse rate: 54 %
We came up with this percentage after calculating that heroin was found on 6 out of 11 boats in random testing. Once you start looking for press releases about addicts among fishermen, it seems the situation really is that horrible. Lobster fishermen are most affected, as it appears. Working conditions are harsh, to put it mildly. Bad weather, long hours, physically demanding actions, and, above all, poverty. A combination of these factors is what lures them into substance abuse.
