2nd hand smoke-will i pass this hair test?

Just got offered a great job, and will be having a hair test within a couple days here. 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 time occured on September 2 of this month, about 2.5 weeks ago. My cousins and their friends were smoking down in the basement, and I was down there with them. I once again stayed fairly far away from the joint, and never came within 10 feet of it. Most of the time, they would light it up and go outside the basement door to smoke. One time though, my cousin did run back inside the basement, and breathe on me. I was a little drunk so don't remember clearly, but I don't remember him breathing smoke on me, but do remember breathing in a "strong" smell of weed coming from his breath. Can't really afford not to get this job so hoping for the best. What are your thoughts? Thanks
