    I think it can be interpreted as being under effect of "something"(medicine etc)

Yes it does.

(very short answer.)


According to the thefreedictionary.com:

be on

  1. To be taking or under the influence of drugs (legal or illegal). They've got me on a load of antibiotics to fight off the infection. He acts so crazy that sometimes I wonder if he's on drugs!

So, yes, it seems to mean exactly that in this context.

It could also mean other things in different contexts:

  1. To be performing or displayed, as on a stage, on television, or in a venue. That new play is on at the National Theater this evening. They're showing my favorite film on TV tonight! I hear there's a great new band on at the bar down the road.
  2. To perform exceptionally well or impressively. The home team is really on tonight, it looks like they'll have an easy victory.
  3. To be in support of, have interest in, or plan to participate in some activity or thing. Yeah, I'm on for having a few drinks later! Mary said she's on to go to a movie tonight.
  4. To do something as planned or according to schedule. Are you still on to pick me up from the airport tomorrow? The meeting is on at five o'clock.
