Trend in heroin seizures over seven years
Between 2015 and 2021, Mexico experienced a
significant decrease in heroin seizures, with the numbers dropping from
546 kg in 2015 to
282 kg in 2021. The
highest quantity of heroin seized occurred in 2015, while the
lowest was recorded in 2021, highlighting a downward trend over the years.
Year-on-year comparison reveals fluctuations
Heroin seizures in Mexico did not follow a consistent pattern, with notable fluctuations observed on a year-on-year basis. The data reveals an
initial increase from
487 kg in 2016 to
492 kg in 2018, followed by a
sharp decline to
282 kg by 2021. These fluctuations indicate variability in either the supply chain,
law enforcement efforts, or both.
Analysis of peak and trough years
The
peak in heroin seizures was observed in 2015 with
546 kg, followed by a gradual decline to the
trough in 2021 with
282 kg. The
43.5% reduction over this period underscores significant changes in either the
narcotics trade or enforcement effectiveness in Mexico.
Comparing recent years to the peak year
When comparing the recent
seizure amounts to the peak year of 2015, there is a noticeable decrease in heroin seizures. Specifically, the amount of heroin seized in 2021 was nearly
half of what was seized in 2015 (
282 kg versus
546 kg), signifying a marked shift in the dynamics of heroin trafficking and law enforcement activities over the years.
Average annual seizures reveal trends
The average annual amount of heroin seized over the seven years stands at approximately
403 kg. This average points to a significant discrepancy when comparing earlier years (such as 2015 and 2016) with more recent years, like 2020 and 2021, indicating a downward trajectory in the volume of heroin seizures.
Year 2019 marked a turning point
The year 2019, with heroin seizures totaling
409 kg, represented a
turning point where the amount seized began to consistently fall below the seven-year average. This shift may reflect a pivotal change in either the strategies employed by
drug trafficking organizations or the enforcement priorities and capabilities of Mexican authorities.
