The United States revealed a rise in methamphetamine

and marijuana (cannabis) confiscations during

the COVID-19 pandemic. Seizures of the two

drugs were higher at their peak in August 2020

then at any time in the year prior to the pandemic.

“At the beginning of the pandemic, it was unclear

how social distancing, travel restrictions and

economic hardship in communities would impact

drug supply and demand,” said Nora D. Volkow,

M.D., NIDA director. “Drug seizure data like these

give us additional insight into the changing drug

use landscape during COVID-19 and may inform

our understanding of rising rates of methamphetamine-

and opioid-involved overdose deaths during the pandemic.”

Measures to address

the COVID-19 pandemic have limited social gatherings, closed international borders, and reduced economic activity across many sectors. While provisional data reveal drug overdose deaths have risen during the pandemic, there is little scientific evidence to illuminate the impact of these measures on drug availability and use in the United States.

Seeking answers, investigators led by Joseph J. Palamar, Ph.D., M.P.H., associate professor at the New York University Grossman School of Medicine and co-investigator on the National Drug Early Warning System (NDEWS), mined data on drug seizures by law enforcement. The data were collect through the High Intensity Drug Trafficking Areas program, a grant program aim at reducing drug trafficking and misuse administer by the Office of National Drug Control Policy in which the Drug Enforcement Administration and the Centers for Disease Control and Prevention play an active role.

Drug seizure data from March 2019

through September 2020 was analyze in five key U.S. regions: Washington, D.C./Baltimore, Chicago, Ohio, New Mexico, and North Florida. Investigators analyzed 29,574 seizures of five drugs: marijuana, methamphetamine, fentanyl, heroin, and cocaine. 

Incidences of marijuana and methamphetamine seizures dipped at the beginning of the pandemic, with low points in April 2020. But confiscations of both substances subsequently rose, exceeding pre-COVID-19 seizure rates and reaching their peaks in August 2020. The quantities of marijuana seized, measured by weight, also climbed significantly from April through September 2020.BUY CANNABIS ONLINE EUROPE

Overdose deaths involving methamphetamine started rising steeply in 2009, and provisional numbers from the CDC show overdose deaths involving stimulant drugs, including methamphetamine, have increased 39% in the year ending in June 2020 compared to the year ending in June 2019. Previous research has found that methamphetamine use has increased significantly among people with an existing opioid use disorder(link is external) and has disproportionately impacted certain racial and ethnic communities, especially American Indians/Alaska Natives.

This work was support by NIDA’s National Drug Early Warning System (U01DA051126 and R01DA044207).
