Definitely not something healthy for you to do...it's good that you came here for help. I will copy this over to the addiction/recovery forum so that you can get more answers.

Say what? I am from the LSD age and smoking a joint with hash in it. What are you chewing on?

Go to drugprevent.org/uk or other sites like this. I've just been searching on the web a little and i read at the site above that petrol sniffing can kill you the first time you do it. I'm guessing that would be the same case for chewing the pieces of paper with petrol on it.

I wouldn't risk it if I were you. It sounds a bit dangerous.
