Lumír Ondřej Hanuš (Hebrew: לומיר הנוש) is a Czech analytic chemist and leading authority in the field of cannabis research.

In 1970, professor Zdeněk Krejčí of the Faculty of Medicine's Department of Hygiene and Epidemiology (where the anti-bacterial effects of cannabis were described in 1955) needed an aide.

There, Hanuš also met professors Jan Kabelík and František Šantavý, who, together with Krejčí, laid the foundations of the research of cannabis and its curative effects.

[8] In Israel, Hanuš and American molecular pharmacologist William Anthony Devane in 1992 first described the structure of Anandamide, an endogenous cannabinoid neurotransmitter.

[8] In April 2010 and September 2011, Hanuš took part in a seminar of the Czech Parliament aimed at introduction of cannabinoid treatment.
