Study undercuts notion that they're given to help the poor, some experts say,,

The researchers found that the use of free drug samples is widespread, with more than 12 percent of Americans receiving one or more free drug samples in 2003. In addition, among those taking at least one prescription drug, 18.7 percent got free samples.

However, few free samples went to the needy, Cutrona and her colleagues found. In fact, those who received free samples were those with better access to medical care. Whites and people who spoke English were also more likely to receive fre
