Among the various methods of identification, cheiloscopy is one of the most interesting emerging techniques. It is a method to establish the identity of a person based on the presence of grooves on the red part of human lips as various studies have revealed the unique nature of lip prints just like finger or footprints. Edmond Locard of France was the first to recommend the use of lip prints for individual identification. Since 1950, the Japanese has carried out extensive research in the matter. Lip prints at a scene of crime, apart from identification, may help to point as to the nature of crime, sex of the person involved, type of cosmetics used, habits or any pathological changes of lips. Credibility of lip prints as a human identification tool for evidential purposes is yet to be accepted by courts in India as literature reveals very little research done in this field. There is a need to review the various methods of recording and collection of the lip prints at the crime scene and also the means to develop the latent lip prints. This paper reviews in detail all the important aspects of cheiloscopy like its scope in crime investigation, limitations and current research carried out in this field.

The availability of poisons and the deficiency of health services in the developing world is leading to a great economic and social set back. It has been found that easy access to large number of pesticides, rodenticides and other daily use chemicals and their ignorant use is leading to hazardous outcome in form of increased number of cases of poisoning related deaths. Recent industrialization and over use of insecticides has lead to a extensive proliferation of toxic chemicals. There is urgent need to devise mechanisms soon for strict regulation of availability and use of these chemicals. Other forms of poisoning includes over dose of prescription drugs such as hypnotics and anti-anxiety agents. Therefore there is need to put emphasis on regulation of dispensing these drugs over the counter and also developing newer antidotes for drug overdoses. With the above considerations there is need for further deepening our thought on prevention and regulation of drugs and chemicals.
