’s policies could leave the US more vulnerable to dangerous synthetic drug trafficking from abroad, even as the  has vowed to stop fentanyl from entering the country, former government officials say.

This week, Trump imposed  on  and , ostensibly as a tactic to stem the flow of illicit drugs into the US.

Jim Crotty, the former Drug Enforcement Administration deputy chief of staff, called the approach “coercive” and said it has the potential to backfire. Federal funding cuts could also leave US borders more insecure, according to Enrique Roig, a former Department of State official who oversaw Bureau of International Narcotics and Law Enforcement Affairs (INL) portfolios and who has also worked with .

US overdose deaths began to  for the first time in 2023, after rising . But Crotty notes this progress is fragile.

“**We’re seeing this decrease in overdose deaths and everyone’s still trying to suss out exactly why. I don’t think now is the time that we want to stop any of those existing efforts because we know that at least some, or a combination of them, have been working,” Crotty said.

Roig agreed: “All this has to be working together in concert.”

Federal funding cuts could put the US behind when it comes to drug detection technology. The global drug supply has increasingly shifted towards highly potent synthetic substances such as fentanyl and . Often, these drugs arrive in the US in the form of powders or precursor chemicals that take up minimal space, and 

Roig says advanced drug detection technology is therefore vital, but Trump’s federal funding and staff cuts mean less money for the latest technology and equipment, and fewer people to install it.

Ram Ben Tzion, the CEO of Publican, which provides drug detection technology to government agencies outside the US, says cutting-edge methods detect suspicious shipments even before they get to the border. Publican uses large language models to flag shipments that “don’t make sense” and are likely to contain illicit substances. For example, his company once found fentanyl precursors in a shipment to a residential address in California. The shipment claimed to contain fashion items, but came from a Chinese construction company.

Similarly, the UN Container Control Programme, which has historically , helps  suspicious shipments . This program has helped authorities around the world  of illicit drugs each year. Roig says federal funding cuts have stalled CCP’s implementation  even though it’s a primary security target for Trump.

Some of Trump’s measures are more showy than they are constructive, Crotty and Roig said. The designation of certain cartels as terrorist organizations “doesn’t do much of anything”.

It’s symbolic, says Crotty, given that they were . Other measures are a harmful waste of money, according to Roig. Just this week, for instance, the administration suspended the use of , including those accused of drug related crimes, due .

Roig says this measure was completely unnecessary, as “Ice already has its own fleet of airplanes” that are much cheaper.

Crotty is concerned the aggression could backfire.

“The Mexican people are protective of their culture and their sovereignty. If you push them too hard, could it do more harm than good?” he said.

Mexico sent 10,000 troops to its US border to cooperate with Trump’s demands, but Crotty says “while in a vacuum that sounds like a whole lot”, Mexico’s border is vast, and drugs are often transported in “minute quantities”. So, the US needs Mexico’s cooperation when it comes to intelligence – otherwise “you’re not going to find the proverbial needle in the haystack”, Crotty said.

Roig said that “it’s important that we do this in cooperation with Mexico and not alienate them,” adding that Trump’s aggressive stance toward China could harm the  negotiating with the Chinese government to cooperate on counternarcotics initiatives.

Massive USAid cuts also threaten programs intended to curb the “root causes” of the drug trade, says Roig. Some USAid-funded programs simultaneously tackled drug smuggling and another one of Trump’s key issues, migration – as 

When Roig worked with USAid, he says he spent a lot of time on “community violence prevention efforts”, including programs to keep young people from joining international crime organizations and cartels. (Notably, the Trump administration has purged .)

If the drug supply does increase, it could mean US overdoses begin to rise again as well. But Crotty is worried we won’t even know if that happens.  at the Centers for Disease Control and Prevention could leave fewer people to track overdose deaths, and Trump’s attack on government data sharing could keep everyone in the dark.

“CDC maintains the overdose death dashboard. A lot of that stuff is data driven. Are they still going to have access to the data?” he said.
