for one, if you are too young to buy a lighter, then you probably shouldn't be smoking weed. i remember buying lighters for fireworks when i was like 14.

secondly, in my opinion, there is no substitute for a lighter at least for smoking out of a bowl. anything else is too much of a hassle to be even worth smoking, even matches. i just make the 4 minute drive to the store and get a gatorade and a lighter.
