Advertisements asking teenage girls to swap sex for the drug ice have been found in the listings of online dating sites.

Personal ads on Craigslist and Locanto in Wollongong are offering much more than the dating cliches of long walks on the beach and a great sense of humour, with drugs including MDMA, marijuana and methamphetamine all offered.

Online dating sites are asking teenage girls to swap sex for drugs

In the past two months, 31 posts from Wollongong to Nowra have offered marijuana and 19 have offered marijuana and methamphetamine under the commonly used street names "420" and "sweet puff" to avoid suspicion.

One advertisement placed on April 28 titled "Looking for teen girls will reward for fun" targeted young female drug users, offering "rewards or puff or both" in return for "fun".
