According to data released this week by the US Sentencing Commission, the number of people sentenced for federal cannabis-related crimes has dropped for the fifth year in a row. Federal prosecutors are still jailing more people for cannabis-related crimes than heroin-related ones, however, despite radical disparities in harm caused by the two substances.
Heroin-related overdose deaths in the United States have more than quadrupled since 2010. 2014 was especially deadly: The number of heroin-related deaths was the highest number of drug overdose deaths on record, climbing to nearly 50,000 in just a single year.
The number of deaths directly attributed to cannabis remains at zero.
