Dr. Laupacis, I'm very interested in your statement that the main barrier to access for most people is the skyrocketing cost of drugs. You gave good examples from about 10 years ago rather than from today. I don't know whether you'd want to comment on this, but you will know that the big pharmaceutical companies claim that these huge costs are what it takes them to develop a new drug.
Do you think the costs of developing a new drug have accelerated by the same factor as the prices of new drugs today?
