True, this is indeed possible. However, note that the FDA survey cited only asked 500 physicians. The survey was also done in 2004, which I believe is prior to the cracking down on gift giving and pharmaceutical companies giving kickbacks to physicians. If I remember correctly, DTC advertising spiked after this happened.

Here's some more recent data (also not super scientific, but probably a decent representation of most physician attitudes today): http://www.mmm-online.com/campaigns/what-doctors-have-to-say...
