They asked and (thankfully) he consented. It doesn't say why they asked, though. He had a bong with him, so maybe it smelled, or he was acting 'weird', or they were just on a fishing expedition.
It definitely doesn't sound like he was trying to hide anything, however. Hopefully he gets whatever help he needs, for his sake and for everyone else's.
