For Some Reason For The Past Couple Of Months My

For some reason for the past couple of months my urine has been smelling like ham a kind of Smokey smell and I have been wondering what it is, I am a rather healthy 16 male and haven't had any problems with urine or anything that could be related, I do not smoke and I don't take drugs, nor am I on any form of medication. This has not been happening for long and is not really effecting my health but I am curious to see what it is and am wondering if it is anything that could be effecting me without me knowing.
