| An open forum for discussing MDMA (ecstasy) and related topics at bluelight.nu. Bluelight is a non-profit organisation that seeks to ameliorte the potential negative impacts of MDMA (harm reduction) by providing factual and relevant information. Only two topics are specifically prohibited: asking for drugs, and selling drugs.
Bluelight attracts an interesting user base and has a very active event meetup scene-- rave culture (such as it is) is fairly well represented.
I have encountered few Internet communities as internationally represented irl.
Of course K-mart also features blue light specials. |
