Coughing is perfectly normal even after years of smoking, but it greatly decreases after you've had a few sessions. And about the tests, I am sorry to tell you, but if they make you the hair drug test(People go with that test really rarely), they can see you've smoked for 3 to even 9 months later, but the normal piss tests only show like 1-2 weeks, if you you use extreame amounts for a long period may be a month, but piss tests can be fucked up easy if you look for a way, and dont worry about the hair test, cuz its made verry rarely by big employers(which really care) and shit, and if you need to take that kind of test, you will have the kindda money(I think its about 40$) to buy something that will make you look clean on the test.
