If i took suboxone 14days ago will it show up on a drug screen?

Unlikely: Firstly, very few people are drug testing for Buprenorphine unless for very specific reasons, and it will not show up on the usual opiate screens. Secondly, a single dose would be unlikely to still be at detection limits 2 weeks later even if they were testing for it, unless it was a very high dose and you have an unusually slow metabolism.
