What (if any) powdered drugs, illegal or pharmaceutical, can be identified by taste or smell - you know, like how the cops do on TV?

[Bonus question: what about trained police dogs - could they identify powdered drugs?]
My guess here is that some illegal substances could be identified, not from a primary taste or smell, but perhaps from the residue of chemicals used in the production process (assuming said process is a little less "refined" than that of a pharmaceutical multi-national)?
