I'm going to sell my depressed cousin some weed
Why would you sell your depressed cousin weed?
They keep asking me to give them some.
You shouldn't give drugs to someone who is depressed like that. It might make their situation worse and make them more depressed.
It's fine. It's good for them anyways.
I don't know if weed is actually good for someone who is depressed. I think you should rethink your plan to sell them weed, because it could really be harmful for them.
