Possession of a legal drug now illegal?

I could be missing something here, but somehow it doesn't look that way.

Near the Michigan/Indiana border, 3 people - ages 46 to 53 - have now been busted for possession of pseudoephedrine.

The drug they had was just a few boxes of over-the-counter sinus medicine they got from pharmacies.

I could be wrong, but there's no indication from the article I've seen that suggests they did anything with the drug other than legally buy it. Nothing in the article indicates they intended to use it for anything other than its legal purpose. Nothing indicates that they crushed the pills up or resold them.

Since when can you be arrested for merely possessing an over-the-counter drug?

Despite all this, police in Michigan promptly seized their car and money. No trial, of course.

The 3 "suspects" were caught when a drugstore noted that they didn't live in the area. Actually they do live in the area. They live in the same county as the store, in fact.

Looks like there may be 3 more innocent victims of America's draconian drug laws.
