I do not believe this is an over-restriction in fact the companies do have many loopholes. During undergraduate I worked part time as a clinical research coordinator for a pain management practice and every week at least 3-4 times a pharmaceutical/medical device representative would come in with lunches worth between 200-300 dollars for the entire office. In fact they would contact the office manager and ask for preference of food and nothing was really off limits in terms of price and this lunch would be enough for the entire office. This would be in addition to the reps pitching new products and research ideas over expensive dinners. While the rules and regulations of this behavior has definitely become more stringent there are still some practices that are legal and questionable in the industry. In fact there are websites where you can view how much physicians receive and from what companies they are receiving the money. I’ve copied on site below for anyone that is curious.
