Good discussion so far. I think there are a few different issues involved in answering radiohead's initial question and deroxor's reply.
Totally agree with Mindash's comment about how it is our job to do the corrections.
Any kind of discussion about recreational drugs is very emotional, and there are serious social and personal consequences around them. A lot (or proabably all of us) of us are also very alienated by mass media and resent the power that a publication or reporter or someone that the reporter quotes has in society at large. One or two inaccurate or stupid news stories can suddenly criminalize/stigamtize a whole whack of us that should not be forced into being criminals or "deviants". We also need to be aware of the pressures put on journalists and publishers to discourage the use of euphoric or mind expanding drugs in general.
A lot of BLers are drug nerds, and I mean that in a very positive sense. Folks on the board are both concerned about accurate information for personal reasons, and ,in a more general way, concerned about basic honesty and "science"*. Given that we have few spaces to talk about this stuff in a meaningful constructive way, the nitpicking and drive to accuracy becomes really important for us. Even with my friends that either dope or informed about dope, it's not easy to find anyone else that knows the difference between a phenthylamine and a tryptamine, or that there are cannabinoid or GABA receptors, or that serotonin does different things in the body, or that many drugs may be structurally dissimilar, pharmacologically dissimilar, but have very similar subjective responses, or why marijuana tea won't work, but ganja milk will. And it makes us mad when "experts" report things that aren't true.
There are other things I'm nerdish about -- certain political/ social/ historical histories, certain philosophical issues, certain art and music things. I got annoyed by a slight error in a book I was reading yesterday, and I knew it was slight (a date was given as 1869 rather than 1871) and not at all relevant to the theme of the book, but because that date and what it was referring to mattered to me. So I got mad.
I think radiohead's comment about people sticking up for their drug(s) of choice is quite right. On another board, not very friendly to druggy stuff, I kept getting shoved by otherwise reasonable people when I defended the use of marijuana as an intoxicant. It was very frustrating. I don't give a shit whether people toke or not, but it does piss me off when tokers or the shit they toke are dumped in stupid unreasonable ways. There are other drugs, legal or illegal depending on place and time, which I think are great and I do have biases for them. Others I feel are a total waste of time.
* By science I mean the whole of knowledge -- chemical, physical, social, experiential, historical, psychological, &tc.
