If he was truly an addict, he would need way more than 10 pills for the entire day to hold him over. This leads me to believe he's just getting started.
My best friends brother would take 30 in one day if you gave them to him. He likes to take 5 at a time.

People straight calling him an addict are probably right, but it doesn't sound like he's been deep into pills for months or anything like that.

He could be new to pills and he's just having some fun for a few weeks or so.

I'd just keep an eye on him and see if he continues.
