She shouldn't be snooping around in your stuff, maybe she was just scared for your health when she found out you smoked too. She probably smelled the smoke on you too and that may have been why she snooped too. She does care for you, maybe you should ask her not to snoop anymore, that it is your decision to smoke if you want, and also try to smoke electronic ciggs instead too. I smoke e-ciggs, there is no smell or ahtrays to deal with either.
