she has to want give support to in the 1st place.an user will only stop using when they are doing it for themselves.if thats the crust then the individual thing you can do is be near when the going gets tough.
relay her how you feel,attain her to join counciling.also if your buying it for her okay STOP
get her to smoke the branch instead
