Do you not like your lungs anymore?

Are you that dense?

I don't think that's a thing.

You can definitely be mentally addicted to weed. Like any substance if you use it for a long time and become somewhat dependent on it it'll be hard to get off of, whether it's physically addicting or not. Just keep yourself busy. When you stop smoking, stuff will start to seem boring, just make sure you're keeping yourself busy, and try to do activities especially with friends.

Why do you even worry when you dont do nothing about it?

We can't stop you, if you like weed, go ahead. If not, just fucking stop.
