On one hand, I can envision Vice President Biden, realizing that drug use is so widespread that it even touches his daughter, would become more sympathetic to other people who use drugs. There are hundreds of thousands people behind bars serving long prison sentences on drug charges. The realization that other people’s kids are living in a cage for doing the same thing that his daughter did could be a transformative experience.
On the other hand, these experiences can cause people to move into another direction. When Jimmy Carter was president, his administration seriously considered marijuana decriminalization. There is even footage of Carter and others in his administration saying that the laws against marijuana are more harmful than the drug.
