How to hide smoking from non smoking parents?

I smoke occasionally and I really enjoy it especially dealing with family problems and drama. So i want to smoke, but how would I hide it from my parents and how would I cover the smell? All my friends have parents that smoke so their parents cant smell it, but I live in a non-smoking house. I know and have heard of people that smoke and hide it from their parents when they dont smoke. Can someone give me tips and tell me how they do it? I'm 17 turning 18 in 3 days and I have my own car I share with my younger sister, but she'll be getting her own car very soon. I don't work, my parents want me to focus on my studies and they give me the money I need for whatever. I have a couple thousands in my bank and at home so I can buy my own cigarettes. They give me allowance too. Oh by the way, my uncle and aunt smoke, but they never smell like it and their house doesnt either. They smoke in the garage and in the backyard. The garage doesnt smell like it and their backyard only smells like it around the area they smoke. So what would you suggest to me about hiding the smell from my parents? And where should I smoke?
