If a two-legged law officer's nose detects marijuana, is that counted as probable cause to search a car?

Question: If a two legged officer's nose can detect marijuana, why use dogs?

Humans can detect smoked marijuana on clothing, hair, etc. Dogs can detect unsmoked marijuana inside containers. My meaning wasn't that humans would deliberately take on the role of drug-sniffing canines, just that if an officer smells marijuana from the clothing of a person, would that be probable cause to search a car? I'm curious as to how much common sense, along with observing constitutional rights, is involved in the process.
