Do I need to worry about a Hair Test?

So here's the low down of my scenario:

I'm a 22yr Female, casual smoker. Last time smoked was in mid October, 3 days straight. Prior to that, sometime in August and prior to that.. probably in April. Overall, my yearly overage of smoking would probably 5 times a year tops. I usually smoke blunts or through a bong. I'm 5'2, weigh about 110 lbs. Not so active with going to the gym, however, I work nightshift at the hospital, so I am pretty busy for 12 hours.

I'm planning to apply for a new job within the next month or so, possibly the latest next year in March of 2009. I don't plan on smoking anymore due to the fact that I will be applying for a new job, in another state, which requires Hair Testing..

Should I worry about any sort of hair test if I plan on staying smoke-free for the next 3 months?

Let's say I get a hair test next month in December? What would my chances of passing be?

Please let me know, I've done my research on this forum and at other forums and I haven't seen any posts with my scenario, since most users are active and I'm a ..once in a while type of user.

Definitely will appreciate any input..

ps.
I also don't want to do the Jerry G or macujo method because I have nice long natural hair that I don't want to tap into..:) :thumbsup:
