Tangerine Snot

For the past three days I've been blowing bright yellow-orange snot associated with an allergic rhinitis like sneezing and congestion but only with my right nostril. I thought it might have been an allergic/infective sinisitis/rhinitis although the symptoms were slightly different to my usual. I have now put two and two together. I did a line of coke (with my right nostril) a couple of days prior to the stream of snot. Strange that this is the first time I've had this reaction. Probably tainted coke.
