President Donald Trump announced on Twitter that he will hold a briefing on the opioid crisis on Tuesday. He will be giving the briefing from his vacation at his private golf course in Bedminster, New Jersey.

Opioid-use in the United States has been an ongoing problem, spiking in the past few years. Trump put together an opioid commission and last month they recommended the president declare a national emergency under either the Public Health Service Act or the Stafford Disaster Relief and Emergency Assistance Act.

Here are some facts about the opioid crisis in the U.S.:

1. Opioids and opiates are technically different versions of painkillers but are often referred to in the same way. Opiates are derived naturally from the narcotic opium, like prescription drugs like Vicodin, Percocet and OxyContin or street drugs like heroin. Opioids once referred to the synthetic version of opiates, like methadone and fentanyl, but now refer commonly to the class of drug as a whole.
