Undergrad classes for someone interested in pharma law

Im a U1 Science in my first year at McGill, and after some deliberation on what kind of studies I want to pursue in life, I’ve decided I want to pursue pharma law in law school after undergrad.

I’m looking for undergrad majors/classes recommendations that could help me get set up for law school (i.e. major in chemistry minor in poli sci).

Any help and recommendations would be great
