I was a drug user before I came across Bluelight, and remain so now. My drug use has changed, but it's always been changing, so I wouldn't necessarily say that Bluelight has affected my drug use.
I find that Bluelight is a great impulse to educate myself further, so that I can answer questions. Someone posts a question and I realise that I don't know the answer, so I go and find out. Then I post whatever I found. I felt the need for a better grounding in the basics, so I've been teaching myself more about physiology and pharmacology. I'm not proud of all my posts -- some are stupid -- but I am proud of the ones where I was able to give an informative and useful answer to a question.
Not having drug-using friends, I've always imagined drug users as being much like myself, rather than whatever the standard 'druggie' is generally meant to be like. Bluelight has made me see that thoughtless people use drugs too. This might seem like a strange sort of realisation, but I've always thought of drug users as introspective, thoughtful, philosophical, interested in their consciousness and in consciousness generally, etc. All the things I like to think I am. Apparently, some really are kids trying to get 'fucked up', whatever that means. Bluelight captures a much wider selection of the drug-using population than most drug-related message boards, which is why I hadn't realised that before.
Oh, hell. I was a kid once. Maybe I'm just getting old.

I hope no-one feels too insulted.
