Our reading
An editorial interpretation.
An exasperated rhetorical question aimed at a group whose behaviour seems so dazed, slow or senseless that the speaker wonders if drugs explain it. The tone appears incredulous and scolding rather than curious, treating their conduct as too foolish to be simply ordinary.
