Federal statistics reveal that law enforcement seized an estimated 1.5 million pounds of marijuana at the US/Mexico border in 2015. That total is the lowest amount reported in a decade and continues a steady year-by-year decline in seizure volume that began in 2009, when nearly 4 million pounds of cannabis were confiscated.
Overall, 99.8 percent of all marijuana seized by federal border patrol agents was seized at the southern border.
It has been previously reported that increases in US marijuana production, particularly the rise of state-authorized commercial growing in jurisdictions like Colorado, has significantly undercut US demand for Mexican-grown cannabis, which is typically presumed to be of lesser quality.
