He's slurring so it's not easy to hear. From a distance and in the situation it might sound like "I ain't doin' any drugs."

Closer up however it sounds a lot more like "I ate too many drugs."

It's quite possible that it's ambiguous and people at the scene may have heard both statements if they heard at all.

The brain tends to predict and fill in so a lot of people would have heard something conforming to "I didn't do nothing." if they couldn't quite hear it.
