of the suggestions mentioned, i would suggest a stove or trying to buy/steal a lighter.
even if your stove isn't gas, heat it up till its red hot, and put the end of the joint near it. should work fine.
that or just go to all of the gas stations in your area. i can't imagine someone being like. "okay that's one lighter taht'll be.... wait... how old are you?"
let us know how it goes.
