During the last few weeks, there was much talk about how placebos may be as effective as Prozac and other SSRI's in combating depression, anxiety, etc.

Being very anti-pharma, I was happy with this. Well, it turns out there are some complications. Read here:

That said, the study does come with one big caveat: the trials it analyzed are all 6-8 weeks long. In that short time frame, Prozac is often no better than a placebo. (Keep in mind that SSRI's rarely produce any positive benefits for the first several weeks, a phenomenon known as the Prozac lag.) However, the performance gap between placebos and SSRI's tends to widen the longer a person is taking the drug. After a while, the placebo effect tends to wear off, which is why people on an "active drug" are less likely to relapse.
