Cops are cool to chill and respectful people. I've been given the go ahead at least 4 times off the top of my head. Probably a few more. Twice I was carrying something, but wasn't noticeably stoned. I'm a guy too. I think it's all about your presence they sense.
Just be chill and respectful. They're trained to pick up on attitude and nervousness. Helps a lot when you conduct yourself like a regular ole Joe Shmoe. Don't be all advertising you're a "______" badass, thug, pimp or whatever, you fill in the blank. If we were all humble Joe Shmoe's and kept our little secrets under wraps this country would be a more chill place. And our little secrets wouldn't scare people into having all these silly laws to supposedly protect "us" from those meany weed peeps.
It's just FREEKIN weed. Relax.
