Puff, The Magic Dragon is NOT a reference to MJ.

I agree, but many people use to think it was a reference to MJ. You have to admit that the song was a bit whimsical and you can understand why many interpreted it to be about weed.
The same sort of thing was said about Lucy in the Sky With Diamonds.... LSD?
It was a song about John's son's little school friend..... nothing more.

People often deny artistic allusions after the public discover them. Gotta go with the evidence on this one.

Kids were joking about that since before the film was released.
