Would you consider a drug safe if some articles in JAMA said it's safe? Maybe some of those guys in the pharmaceutical boards of directors exercise editorial control of what's published? The media certainly is controlled by a very small group of people like Rupert Murdoch and Rogers, so whatever articles you read about 'dangerous' drugs is being allowed by these guys. If these drugs were indeed lucrative and corrupt schemes, I'm sure the companies could make payoffs to keep these things out of the media.
The media is already tightly controlled in political matters like war - casualties and the tortures conducted by our armies, and the media is used for propaganda, like "terrorism". Unfortunately, the public are calloused sheep... they do not want to receive news from al-Jazeera, they do not care when 1 million brown or black people are brutally massacred, they do not care enough to rise against abusive governments that take away 1/3 of their income in "taxes", just the same way they keep on smoking cigs when the packages clearly show them pictures of the cancers they will get.
