Would you do this to your partner?

I'm 18 and in college so I'd probably be smoking with my gf if I had one. But I'm gonna quit when I finish college. So if it was my wife and we had kids I'd get mad because I know what weed does to you and thats not appropriate around children. And also I live in Marin County, CA, its whats on the other side of the Golden Gate Bridge. Its the richest part of California and has the highest rates of teen drinking and marijuana use in the country and basically every kid I know smokes so its not a big deal out here.
