My cousin has to take a swab test in a little less than2weeks. how can he p. onl serious answers please.?

What kind of swab test...?? If it is for drugs, then your cousin can p by not doing drugs...If its for STD's if your cousin doesnt already have one then tell them not to sleep around and increase their chances of STD's..If they already have a STD then there wont be anything they can do to prevent it from showing up on the swab..
