The possibility of using odor traces during the investigation of crimes in the sphere of drug trafficking is proved. In particular, it is possible to use such traces as a means of identification of individuals involved in contactless drug sales (persons directly laying such items); in certain cases – individuals involved in transborder drug delivery (so called «ownerless cargo») and individuals involving other persons in drug trafficking for a certain fee without informing about real content of such «transfers». It is noted that information about a person can be carried by different material objects: a) solid and liquid particles separated from human body – pieces of cloth, hair, blood, sweat and fat substances and another excretions of human physiological activity; b) items of constant human contact – clothes, footwear, private things; c) objects of temporary contact with human body – things of material environment, surfaces touched directly or indirectly in the process of crime committing, objects of labor and instruments; for example, human odor traces are created by direct contact with syringes or drug package, bags or other objects containing drugs.
