The study gave guinea pigs the same drug as mentioned in the claim and checked their lungs for 30 days — it found the drug was still there, proving it sticks around longer in the lungs than in other parts of the body.

When guinea pigs were given a specific drug called ractopamine every day for a week, the drug stayed in their lungs much longer than in other organs—even 30 days later—like it got stuck there and took its time leaving.

When guinea pigs were given a specific drug called ractopamine every day for a week, the drug stayed longest and in the highest amount in their lungs the day after they stopped taking it—much more than in their muscles, which had almost none.
