I haven't actually smoked mary jane myself since February 2011, almost 1.5 years ago, but I have been around second hand smoke lately. Back in the middle of August last month, hung out with some people in a fairly large room (10 feet x 25 feet) with the door closed. I was never within 10 feet of the joint or bong, the people were on the other side of the room. They smoked for about an hour. The second Rating: 5
