Well I wan't directly involved in it but from what I understand the drug companies "allegedly" tried their hardest to suppress research that suggested that SSRi antidepressants (like Prozac, Seroxat etc.) increase suicide risk particularly in younger people.

This was a matter of considerable and heated debate in the medical/psychiatric community for some time.

I am not an expert on it but I think you can probably find a lot useful information from medical/psychiatric sources on this - a lot of esteemed journals covered it.

I might do a post on it in the future after doing more research as I don't want to get the facts wrong and end up getting into trouble for that as they (drug companies) do have a lot of power and lawyers!
