not the lighters i use. and the butane i use is 5X filtered. it is made to be free of additives so it doesn't clog the inner workings of fine lighters or alter the taste of expensive cigars. i will not use "whatever else i may have handy".jus so you FDD naptha is also in lighter fluid.
i see these threads and all i think is "meth". it's a personal issue that apparently i need to get over.
i'm still not smoking any.
