It would appear English is a 2nd language, so I'm wondering if you are conveying things accurately.
If you mean that you smoked tobacco for ONLY two weeks (vs you said you STOPPED for two weeks), you might have a chance. Claim depression from stress.
However, if what you originally wrote is correct -- that is you have been smoking for months or years and you just stopped 2 weeks ago after being "found out", then you are fucked. But, you might be able to be reinstated if you kiss ass for about 6 months and convince them it was a stress related slip back.
