This is something I've been unsure of for a long time and I can't quite figure out my answer. How important is the quality of butane if I'm using it in a torch for my Vapcap M?

The butane never comes into contact with my herb or anything I'm inhaling so I imagine it's fine there compared to if I was using it for like a sticky brick where there's a more direct "connection" between the butane and herb.

Will it fuck up my torch? I don't know what was in it originally, guy at the shop just filled it up, but I imagine it wasn't some high quality shit.

My googling seems to imply that it may clog the Jets to use a lower quality butane, but how big is this risk realistically if anyone's tried it out?
