How many people are in jail for drug possession?

As of recent estimates, approximately 250,000 to 300,000 individuals are incarcerated in the United States for drug possession offenses. This number can fluctuate based on enforcement practices and changes in drug laws. It's important to note that many people are also incarcerated for drug-related offenses that involve trafficking or distribution, which complicates the total count for possession alone. Additionally, trends in drug policy reform may affect future incarceration rates.
