• If you look at the expenses of a great pharmaceutical company, they pay between about 10 to 15 percent of their expenses for research, but they use 30 to 40 percent of their incomes for marketing and promotion. It is not completely wrong that they spend so much, but it is not correct to say that there is a direct connection between the price of drugs and the cost of research. It could be more between the cost of marketing and the cost of the drugs.
