Action Scientist: The Doors of Perception move

The Doors of Perception: By using advanced psychological, pharmacological, or mental interface techniques, you may use magic with +Sharp instead of +Weird.
You may choose one of these additional effects:

• Communicate with someone or something that you cannot communicate with by normal means.
• Analyse a clue (allowing you to investigate a mystery in a way that you would not normally be able to).
• Give a hunter (including yourself) +1 to a rating for the remainder of the mystery (maximum +3).

During our last session Javert (Professional) take this Action Scientist move. He tried to use it when some policemen pinned us in an abandoned house. He said he read the smoke of his cigarette.

Does it count as a valid use? What do you mean with «By using advanced psychological, pharmacological, or mental interface techniques»?

My rule to allow it would be: if the player can come up with a weird science explanation for why it works, then it does.

An alternative test is that if you could imagine Walter Bishop doing it on Fringe, then it's acceptable.
