You weren't doing drugs. You trieddrugs. Big difference.

As for your mom: sit down and talk to her. I think she is more worried rather than not-trusting.

Talk to her like an adult. Tell her that you tried it and you did not like it (maybe) and that you are not planning on doing it again. Also tell her that you came to her BECAUSE you did not want to lie....so not trusting you does not make sense. She is an adult, I am sure she will understand.

Talk to your mom. Tell her that you tried it a couple times and you will never do it again. I know I kinda stole Deamons answer but thats all I can think of

I think that your mom might feel a little weary about this because she obviously cares about you and doesn't want you to get mixed up with the wrong kind of thing, know what I mean? Your best bet would be to sit down and talk to your mom about what happened. She might not trust you one-hundred percent right now because of the drug thing, and that's understandable. If you want her to trust you again you're going to have to earn it, which isn't easy to do but it's achievable. It might take a bit of time and effort but it'll all be worth it in the end. =)

I hope that everything works out for you. Good luck with everything.

Take care of yourself.

yeah, just talk to her, its not like she will kill you for trying to have a convo. with her. the see what happens and no matter what, don't turn it into an argument or u r screwed

Just take the initiative to show her that she has reason to trust you. I'd advise picking up some pamphlets from teen resources at school or clinics and show that you're responsible and even have information about the topic just in case. Show you have the ability to be trusted and it'll slowly come back. Talking to her is the best solution.

Sorry But your mom is a little more right than you... but out of that you should talk to her and then you might do something that will take back her trust about you ;]
Ihaven't nothing else to say

Trust takes a while to gain. As long as you assure your mom that what you did was only to satisfy your curiosity, and that you know drugs are horrible for your health and mental well-being, your mom will know at least that you're well informed. Appease her for the time being, and she'll gradually come to trust you again as long as you behave.
