> a huge swath of the population will be dealing with issues 30 years form now
We've got 20 years of data on this class of drug. Certainly there could be some long term issues that we're not aware of yet, but it's not likely that there are significant issues that affect a large percentage of users after 30 years that didn't affect the small sample of users that have been using it for 20 years or the massive number of users that have been using it for 10.
How much of the data was done independent and how much was done by the same company or companies that benefit from it? We've seen this before. How many decades did people take aspirin thinking it was good for you to take everyday. How many decades did people drink wine thinking it was good for you in small dosage? How many people smoked using it as an appetite suppressant not knowing the long term effects?
The list goes on forever. I'm betting this ends the same way.
