Hundreds of thousands of fentanyl pills found on a train were seized by customs officials on the Mexico border in Arizona this week.

A train was searched by officials from the US Customs and Border Protection as it came into Nogales, Arizona on Wednesday.

The train was carrying 736,200 fentanyl pills and 196 pounds of methamphetamines in one rail car, the Port Director Michael Humphries said.

What do those drugs look like piled up together? Like this:

Meth is very bad. We all know that. We also know fentanyl is bad. But it's kind of hard to fathom just how bad the latter is:

'It is a highly addictive man-made opioid that is 50 times more potent than heroin. Just two milligrams of fentanyl, the small amount that fits on the tip of a pencil, is considered a potentially deadly dose,' [the DEA] said.

We know "two milligrams" is tiny. But here's how tiny it really is:

So yes, those 736,200 fentanyl pills represent a genuinely staggering number of potential overdoses and deaths.

Just another reason we need our border secured immediately.
