Look kid .... Thank you for being intelligent by asking. You have some sense. Heck, you might very well be a genius. But you know what? No one will ever know how talented and smart you are if you are Huffing Paint.
It will cause severe brain damage. Not over a long period but right away make you STUPID!
Are you really that bored? I didn't think you were serious about doing this but maybe you are the only one who can help someone who is not as intelligent as you are.
I am going to say a prayer right now that you are going to reach out to someone who is in trouble, tell them that you care, and get them away from sniffing glue, paint, or any other harmful agents.
You can do it and make a difference. I trust that you will be that positive influence on someone who needs you.
