Why do a lot of teenagers smoke weed and drink?

And then put the pictures of their plants and bottles all over Instagram and Twitter

There stupid

Because they are idiots. I know a lot of kids who do it and I scare the carp out of them with it in an effort to get them to stop being so stupid. It's like laying the table for the cops to arrest you.

To look cool.

I've never smoked or drank before.
I play video games, cuddle with my cat (because I'm single and lonely), and go to the gym on a daily basis.

My parents should be proud of me.

May be they want everything early..

[Rose hathaway]

Some of them want to look cool, others just do it for the fun, I guess. As for posting pictures of the stuff they did and drank, I'm assuming it's because they want to show off.
