I was at a festival last weekend and saw my first custom / hacked vaporizer, similar to the one at right (click to embiggen). The hack is putting in a coil with less resistance that heats the liquid faster. The other part of vaping culture is the creation of different liquids, some of which have gotten vaporists in trouble with organizations like the Girl Scouts (because of Thin Mint vaping liquid).
Related to that, I thought this response to the World Health Organization’s call to regulate vaporizers was interesting:
“For the WHO to suggest that e-cigarettes are as risky as other tobacco products would send an erroneous and bleak message to the millions of current e-cigarette users who have used them to quit smoking,” Robert West, a University College London researcher and a signatory of the letter, says in a statement. “It would discourage smokers from trying them and we would miss out on a major opportunity to reduce smoke-related deaths globally.”
