before or after beatles took drugs

which music do you enjoy more from the Beatles, before or after they did drugs?

Im not a big beatles fan....favourite song would be "come together"...dont know if thats after or before they did drugs...

that was after....pretty much there albulms before Rubber Soul were when they didnt do drugs but Rubber Soul and there albulms after that were wen they first started experimenting with drugs and there music changed for the better imo
