I loved you much;
It's not enough
You love blow
And I love puff
They really love each other, but love wasn’t enough to overcome the fundamental differences between them. They each come from very different scenes: he’s a cocaine user (blow) and she smokes weed/pot/marijuana (puff), illustrating the prominent role that drugs play in Amy’s life and relationships.
A cocaine user, being energetic and neurotic, is probably terrible company for a sedate and lethargic pothead (marijuana user) that just wants to “chill”.
