Agreed, If you're staying with your parents, respect them, respect their wish. I'm 44, I never smoke a single puff in front of my parents before.
Every parents will find it hard to accept when they first found out what their children do that against their wish. Especially it comes to smoking. To them, everything that comes from tobacco is addictive. And addiction is bad. Slowly, you're only 18 this year. If you live until 100 year old, you still have 82 years to enjoy your pipe, or whatever you want to do.
So, slowly. Don't rush in. It's been 18 years they know that you don't smoke, or won't smoke, don't expect 1 year they'll accept that you smoke.
