I've actually been on the lightrail when some junkies got on and started smoking drugs off aluminum foil. The smell eventually made its way through the entire car. Someone must've reported it though because the train stopped randomly and there was a random announcement over the intercom about an unexpected delay. I think the junkies knew what was up and got off the train. This was one random ride too. Makes me think it happens a lot.
