“The Scientist” is a documentary that traces the story of Dr Mechoulam from his early days……as a child of the Holocaust in Bulgaria, through his immigration to Israel, and his career as the chief investigator into the chemistry and biology of the world’s most misunderstood plant. Dr. Mechoulam ascertained that THC interacts with the largest receptor system in the human body, the endocannabinoid system (ECS).

Raphael Mechoulam Gets the Biopic He Deserves


In The Scientist Klein plays the curious Everyman who questions Mechoulam about cannabis and how it works in the body. (Klein’s face is handsomer and more expressive than Everyman’s.) The interviews are conducted in the pleasant Jerusalem apartment where Raphe and Dahlia Mechoulam have lived since 1966, and in Mechoulam’s lab at Hebrew University, and in his car as the scientist drives to and from work, and at a meeting of the International Canabinoid Research Society (a group Mechoulam helped organize).

Klein occasionally carries a potted cannabis plant —a signature prop, like Charlie Chaplin’s cane.

The Doctor Synonymous with THC Research Forges Onward

Zach Klein, the documentarian behind the film “The Scientist,” is a multifaceted individual. Klein was working in Israeli TV, specifically Israeli Sesame Street, while also pursuing a degree in environmental studies when his mother received a dire diagnosis. It was this diagnosis that lead him to examine medical cannabis, eventually establishing both a friendship and working relationship with the Israeli biochemist who, among other achievements, discovered THC in 1964. Now, both Klein and the man known as the grandfather of medical cannabis research, Professor Raphael Mechoulam, have joined together in creating a film to emphasize the importance of the endocannabinoid system, a mechanism that scientists stateside have speculated may have therapeutic potential to treat all human diseases.
