I've NEVER been in trouble with cops, probably because I only smoke at home. Only sometimes do I smoke outside.

Well, this ONE time outside..

I was smoking out of this little pipe I had that can fit on the palm of my hand. I took a pretty big hit and saw a cop car driving slowly my way. It finally reached me but didn't stop or anything, though the driver was staring at me. I held that smoke in my mouth for a LONG time until they were about 20 feet away and finally blew my smoke which pretty much became a ghost smoke cause it all went down to my stomach, lol!
Burped it out later though.
