Quick answer, no. Nicotine is what they look for when they are doing specific tests to see if you are a smoker or not. Nothing else in the e-juice will show up in any tests.

Congratulations on making the switch! I've been vaping for a year today and will never look back. Who knew we could actually enjoy quitting?!?!? As far as your question, sub-ohming can be very nice. I do, but I also have a Nautilus that I use regularly as well. The key to sub ohm-ing is understanding battery safety. If you don't have a firm grasp on ohms law and battery safety, then sub ohming can still be done, you just need to make sure you're doing it right. First, the battery you're using is not powerful enough for sub ohming, so you'll need to upgrade. I would suggest, if this is something you really want to do, you try getting something like an eleaf 30watt with a subtank nano. They are the perfect size for each other. The 30watt is the same size as the 20 you're used to, and everything is regulated. You don't have to worry about the battery safety, because everything is already done for you. Pre-built coils, a regulated battery designed to hit the coil you've got. You'll know if you've turned the wattage up to high because it will start to taste burnt, then you just turn it down a bit and you're good to go. The maintenance of this set up is no different than what you do with a standard tank. If it's something you really want to try, this is where I would suggest you start. Safe and simple way to dip your toe in.
