First of all, welcome to TeenHelp! I hope you enjoy your time here. Now, on to your actual post:

The first step in quitting any addiction is admitting that there is a problem and that you need help. You've already done that, which is something that you should be incredibly proud of. I know it isn't an easy step to take.

However, this isn't something that you can do on your own. As difficult of a task as this might seem, you really need to reach out to those people that you used to be close to and ask for their support as you take this journey. Honestly, they might not be willing to at first - they might be a little hurt from the effects that marijuana has had on your relationship with them. But, if you sincerely apologize to them and let them know how badly you want to change, I'm sure you'll find some that will be willing to help you along the way.

This might sound obvious, but you really need to be willing to do the work. Remove yourself from situations that might tempt you to smoke. At this point in your recovery, it's not enough to simply say you're not going to do it. You can't give yourself an opportunity to do it. That might mean staying home instead of going to parties or missing out on something that you were really looking forward to. But, if you're determined to quit, you need to focus all your energy on that, no matter what else it might mean for you.

I hope this helped!
