Olivier Bernard, known as the Pharmafist (Le Pharmachien), is a Canadian science communicator who uses cartoons to counter pseudo-scientific myths.

[5] Bernard uses a colourful style, described by emergency physician Alain Vadeboncoeur as "friendly, but confident, perhaps a little of a smart-ass", but "he does not attack people, only practices, ideas and concepts.

"[6] As a science communicator, Bernard says he's influenced by Vadeboncoeur, as well as astrophysicists Hubert Reeves and Neil deGrasse Tyson.

[7] Through his website, the Pharmafist aims to "destroy scientific myths and health beliefs and (...) encourages people to develop critical thinking and to make better choices about vaccines, gluten, nutritional complements, sugar or useless cold medicines.

[18][19] They feature Olivier Bernard in his role as the Pharmafist, offering a scientific viewpoint on health care, through experiments, interviews, cartoons and humour.

[20] In the program, Bernard experiments on himself with many treatments he denounces as being ineffective: natural sunscreen, homeopathic solutions, products meant to change the acidity of one's urine.

[21] Bernard released in 2020 an eight-episodes podcast on the 2011 death of Chantal Lavigne, during a New Age sudation workshop.
