it really isnt that dangerous. take FDD (staff for this site). he has a thread somewhere on here that shows him making it while smoking, not as dangerous as some would like us to believe. and i have done it for years without any problem. just remember it is butane... but also remember that is you have a lit joint of ciggarette and you take a butane lighter and just run the fluid, no matter how close the cherry of the cig or joint gets to the stream of butane leaving the lighter, it will not ignite. you must have a flame or spark to do that. good luck.
