It is bad that kids as young as 11 are doing all these things but it's not anything new. People have more freedom now but young adults have always tried to grow up too soon and expose themselves to forbidden things. 50-60 years ago kids were sneaking cigarettes as young as 11 and also drinking, probably having sex as well. I know for sure about the smoking thing because my mother said she first tried it around that age.

If I were you I wouldn't worry about it, just do what you think is right for yourself.
