@irenea8, this is a question that researchers are studying, called pharmacogenomics — also known as pharmacogenetics or PGx. Pharmacogenomic testing uses your genetics to help predict the way you will react to a drug.

What is pharmacogenomic testing and who is it for? https://mcpress.mayoclinic.org/living-well/what-is-pharmacogenomic-testing-and-who-is-it-for/

Irene, were you aware of genetic testing related to one's ability to metabolize drugs?
