Elsewhere in the book, Hari has suggested that it would be better for drug users to get pure, medical-grade drugs for several reasons. Most importantly, the dangerous adulterants in drugs wouldn’t affect their health, and they would be able to choose the precise dose they want to use, rather than gambling with drugs of unknown strength. Medical-grade drugs would be cheaper and more reliably available, which would save drug users time and money. Similarly, drug users wouldn’t have to risk dealing with violence in order to get them. But perhaps most importantly, a legalized drug market would shut down the organized drug crime that has plagued places like Ciudad Juárez and hollowed out institutions like the Mexican justice system.
