I have. I had a drag today. But I almost choked! If I have a full one, it seems to be done in seconds, and I am grabbing my 510 to kill the nasty taste and get a real hit. I wouldn't smoke any at all if my girlfriend didn't smoke. I steal one every once in a while and every time I am disappointed that they don't taste like before, but then glad that I have found something so much better.
