[Usefulness of the initial medical examination on matters relating to persons suspected of driving under the influence of amphetamine and its analogs or delta9-tetrahydrocannabinol based on the materials the Department of Forensic Medicine, Pomeranian Medical University in Szczecin].

Introduction: Polish law forbids persons to drive under the influence of intoxicating substances, and those after the use of substances producing effects similar to alcohol. Therefore, there is a need to give an opinion based on a blood test, to establish whether or not the person from whom the blood was taken was under the influence of an intoxicating substance or after use of the drug while driving. Some authors reported that the final opinion should take into account chemical and toxicology test results identifying the parent compound and/or the metabolite only, but also the sampling time of the material to be analyzed in relation to the driving time, the result of the medical examination conducted prior to the collection of material for analysis, and the results of screening tests executed at the scene.

[Comparative tests of ethyl alcohol concentrations in blood, vitreous body of an eye and urine collected from a corpse].

In the work research into alcohol content in the vitreous body and blood collected from 290 corpses was done. A statistical analysis was carried out and it presented a high dependency between alcohol content in blood and in vitreous body, which gave grounds to the assumption that the vitreous body is a good material for marking ethanol post mortem in cases when collecting blood is impossible.
