Possible to pass this hair an urine test?

18yrs old Male 5ft10 163lbs Sorry for another will I pass thread, but anyways here it is.

I really dont smoke often at all. I smoked on June 1, 2013. That one doesn't really matter anymore. Then October 28, 2013 i smoked, and on December 21, 2013 I sat in a car where people were hotboxing for about 10-20min then they opened the windows(i didnt smoke), but they told me i was still getting high but i didn't feel anything.My eyes didn't get bloodshot either like they did on Jan 2 when i did smoke. Most recently Jan 2, 2013 car windows were open. Also when I smoke I usually only take 2-4hits.

I haven't applied to this place yet but my parents are expecting me to. The place does a hair and urine test. I'm not worried about the piss test, but should I procrastinate until April when its been 90days? Thanks
