There are other methods of lighting a bong or pipe, don't have to use butane.

Stormcrow, you might cancel a lot of the respiratory benefits from vaporizing at a high temperature but the medical benefits (CBD in specific) are acheived from vaporizing at higher temps. Low temps ie hardly any "vapor/smoke" primarily vaporize thc with little to no CBD. It's more of a head high.
