I had a friend get pulled over in Nevada because a cop thought he spotted him smoking a bowl(which he was)...so he asked to search my friends car..and my friend consented....and he called in a drug dog ANYWAY...and after the search and he found nothing(amazingly enough)....he left my friend go..just as the drug searchers were pulling up...

I was camping once and had a forest ranger dude catch me and my friends smoking weed..and he said he tried to get another officer out there and a drug dog but no one would do it...dumbass....
