This is incredibly sad... I am 28 years old and married and I have still never told my parents I smoke.  Cigarettes that is.  Let alone pot.

Unfortunately I am not a very good liar and I think they may have figured me out.   I'm pretty sure I know what tipped them off.  It's not the time I went on holiday with them and had to go to the ladies' room for 20 minutes after every meal, or made strange trips to phone booths to call my husband.  It's not the yellowish tinge to my teeth (my father's a dentist but I just tell him I drink 10 cups of coffee a day).   It's not the aroma of smoke that clings to my clothes.  It's not the strange brown patch over the driver's side of my car.  No.  What I think may have given them some suspicions is the time when I went to visit my mother and a packet of Marlboro lights fell out of my jacket and my mother asked if they were mine and I said, "No, they're my friend Lola's."  Lola?  I am still kicking myself for not thinking up a more plausible name.
