Americans struggling with addiction need treatment and reduced access to deadly drugs. They do not need a taxpayer-sponsored haven to shoot up.

Rod J. Rosenstein: Almost 64,000 Americans died of drug overdoses in 2016, a shocking 54 percent increase since 2012. Dangerous opioids such as heroin and fentanyl contributed to two-thirds of the deaths. This killer knows no geographic, socioeconomic or age limits. It strikes city dwellers and Midwestern farmers, Hollywood celebrities and homeless veterans, grandparents and teenagers.

Remarkably, law enforcement efforts actually declined while deaths were on the rise. Federal drug prosecutions fell by 23 percent from 2011 to 2016, and the median drug sentence doled out to drug traffickers decreased by 20 percent from 2009 to 2016.

The Trump administration is working to reverse those trends. Prosecutions of drug traffickers are on the rise, and the surge in overdose deaths is slowing.

Unfortunately, some cities and counties are considering sponsoring centers where drug users can abuse dangerous illegal drugs with government help. Advocates euphemistically call them “safe injection sites,” but they are very dangerous and would only make the opioid crisis worse.

These centers would be modeled on those operating in Canada and some European countries. They invite visitors to use heroin, fentanyl and other deadly drugs without fear of arrest. The policy is “B.Y.O.D.” — bring your own drugs — but staff members help people abuse drugs by providing needles and stand ready to resuscitate addicts who overdose.

Last year, San Francisco assembled a task force to establish an injection site, and last week the California State Senate passed a bill that would allow San Francisco to operate such sites and grant legal immunity to the drug users who visit them. In May, the mayor of New York City announced a plan to open four injection sites. A Seattle task force approved a similar plan, and city officials have pitched outfitting a van as a mobile injection site. Numerous states, including Colorado, Massachusetts, Vermont and Maine, have explored similar options to help their residents use hard-core drugs.

One obvious problem with injection sites is that they are illegal. It is a federal felony to maintain any location for the purpose of facilitating illicit drug use. Violations are punishable by up to 20 years in prison, hefty fines and forfeiture of the property used in the criminal activity. The law also authorizes the federal government to obtain civil injunctions against violators. Because federal law clearly prohibits injection sites, cities and counties should expect the Department of Justice to meet the opening of any injection site with swift and aggressive action.

Proponents of injection sites say they make drug use safer, but they actually create serious public safety risks. Many people addicted to opioids use illicit fentanyl or one of its analogues, which can be up to 5,000 times more powerful than heroin. Users often have no idea what they are actually buying from criminal drug dealers. Moreover, a bystander or emergency medical worker who comes into contact with such drugs can be gravely harmed.

Additionally, injection sites destroy the surrounding community. When drug users flock to a site, drug dealers follow, bringing with them violence and despair, posing a danger to neighbors and law-abiding visitors. For instance, the area near an injection site in Vancouver, British Columbia, was described by a member of the Redmond, Wash., City Council as “a war zone” with “drug-addled, glassy-eyed people strewn about” and “active drug dealing going on in plain sight.”

Injection sites do not help drug users overcome addiction. Most visitors simply walk in, get high and stumble out. Some estimates suggest that as few as 10 percent of injection site users find their way into treatment. The rest continue the downward spiral of addiction.

Supporters also ignore the unintended consequences on the next generation. Injection sites normalize drug use and facilitate addiction by sending a powerful message to teenagers that the government thinks illegal drugs can be used safely.

That is not the way to end the opioid crisis. Americans struggling with addiction need treatment and reduced access to deadly drugs. They do not need a taxpayer-sponsored haven to shoot up.

To end the drug crisis, we should educate everyone about the dangers of opioid drugs, help drug users get treatment and aggressively prosecute criminals who supply the deadly poison. Under the leadership of President Trump and Attorney General Jeff Sessions, the Department of Justice is delivering results. Many federal, state and local agencies are working with us to combat opioid addiction. Cities and counties should join us and fight drug abuse, not subsidize it.
