How do you tell one of your best friends not to do drugs?

Be stern and strict. Tell her she needs to stop because it's bad for her and she'll regret it later in life. Shes the one whos being an asshole for doing the drugs. I know it sounds like a 2nd grade thing, but imply that you wont be friends with her unless she tries to quit. Hope that helps.

Just tell her you don't smoke weed, it's simple, you'll only sound like an asshole if you start preaching and telling her to stop. If you just acknowledge that some people like it and that's ok but you don't, there shouldn't be a problem.

Who cares if u sound like an ***hole, it's 4 the best 4 u & ur friend.

you can tell her but as a pot smoker my self lol she not going to really care nor stop just prob not talk about it to your or do it near you is all...

sorrry but iv had friends who didnt like it never changed nothing and them telling me how much they hated it never really bothered me either so just tell her

you dont you join them
