RUN! As fast as you can away from her. I know its a shame but she is doomed.
Save yourself.
I hate to say this, but if you fight this she will just hide it. There is a huge pot smoking movement out there. It would be a bad thing to force this issue to much, I know.
The best way to deal this is to keep telling her how this does not make you comfortable with things. But in the end it may just be something you have to deal with or lose her over…..
End the relationship, she is not honest and uses drugs. Wake up!
Speak to her like an adult. When you do, don't speak as if you are better than her or reprimanding her. Ask her to help you to understand what is going on.
Once the ice is broken, explain that you know she does not want to you or herself but you are concerned. Most important thing is to make it about her, not you.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
