What exactly is the difference between generic medications and name brand? is it just a way for the big drug companies to get more money? if i am taking something like methadone for pain, is there a difference in the strength between the generic and the name brand? does it have something to do with research? i don't get it.

when i look these medications up online, everything seems to be the same. so why bother with having two?
