I just started taking Ortho Tri-cyclen Lo, and I haven't been on it for almost two years. When I was on it before, I didn't smoke. Now, I smoke like 3-7 times a week. (It takes me a couple weeks to finish a pack even if I let people bum some off me.) The only thing I've ever read about the pill and smoking says: I'm 21 and cutting back because cigs are starting to gross me out anyway, but I like to smoke when I drink. I'm just wondering... does smoking decrease the effectiveness of the pill?
