Melbourne's Craigslist website has become a digital den of iniquity, with ice, weed, LSD, worn underwear and sex being sold on the site.

A week after police charged a Fitzroy North man for selling crystal meth, or ice, on an online classifieds site, advertisements for the drug - codenamed "puff", "cold" and "ice cream" - were still rampant on Craigslist.

Dealers from across the city promise quick delivery, using sale pitches that vary from "Sweeter than your usual", "Trade good stuff for iphone5s" to "Party with Queen Elsa" and, in a homage to Breaking Bad's meth cook protagonist, "Walter White approves of this".

Ice is not the only vice peddled on the site with steroids, cannabis, LSD, sex and second-hand underwear ("Used laced panties, $30") all readily available.
