I think lobbying and big pharma is an issue. I do not think it applies in a blanket way across the board. I am hesitant to take anything new because it always starts out as a money grab. I take adderall for adhd and its been around for years and I remember when vyvnase came out. Coupons and info in every doctor's office and (surprise) no generic. Even though there is a generic out of the USA the corrupt patent industry in the US allows companies to renew their patents to stifle competition. I have tried vyvanse and it does not last its purported 12 hours and magically once SHIRE had to make adderall a generic vyvanse popped up.
