[Abbr: Acd. Jr. AJFSc]An Insight to Marijuana: Psychological Overview
by Pallavi Mohanty
Cannabis, also known as “Marijuana” is a psychoactive substance and the most illicit trafficked and consumed drug among the youths. Marijuana is dried and shredded parts of the ‘Cannabis Sativa’ plant. Due to the consumption of high doses of marijuana for recreational purposes in adulthood causes cannabis dependence syndrome (CDS) and also may lead to psychosis. Not only dependency but also alters their perception towards everything leading to determent in their cognitive disability. In the current scenario, teens are more prevalent to abuse marijuana than adults. So, it’s high time to let the teens and adults know about the psychological pros and cons of marijuana before its consumption, which may help them to prevent their near future. It’s never too late to take steps against the ‘Substance Abuse’ among the youngsters. In the context of current issues related to adolescent & teens associated with marijuana use is explained, focusing on those areas related to its adverse psychological effect. Keywords: Marijuana, THC, Cognitive Disability, Psychosis, Cannabis Dependency.
Entomotoxicology: An Alternative for Biological Specimens
by Falak Khan, Afrozulla Khan Z
Forensic entomology is the utilization of insects in lawful issues and gets information about where, when, and the way crime was committed based on their distribution, ecology, biology, and conduct of insects present at the crime scene. Entomotoxicology is the assessment of poisons in arthropods that prey on the corpse. Forensic Entomotoxicology examines the assessment of insects as toxicological samples since they are being used for the poisonous content in them. The utilization of insects as an alternative matrix for drug identification is well-reported and suggested without conventional matrices for example urine, blood, or internal organs. Hence, drugs present in a decomposing body might be recognized through the investigation of maggots feeding off it. In this paper, the results for the practice of Entomotoxicology as a forensic technique are discussed in-depth and the function of insects as a toxicological sample, its collection, and preservation, examination utilizing different instrumental procedures, is being stated for the forensic considerations. Keywords: Entomotoxicology, Forensic Entomology, Toxins, Corpse, Insects, Investigation.
Role of Computer Analysis Tools in Forensic Science
by Preeti Kiran, Ranjeet K. Singh
As the world is entering into the digital era and the entire information about a person could be found online, so the reporting of computer crimes are increasing daily. To solve computer crimes, it is necessary to study digital forensics, which includes the methodology of retrieving and examination of content stored on digital devices, including desktops, laptops, smartphones, etc. Due to the vulnerabilities that have caused an increase in computer crime, there are numerous tools present for the analysis of these vulnerabilities. Examiners need a solution that puts all of the knowledge together and automates some of the repetitive acquisition and processing processes, freeing up time for deeper study. In this paper, various forensic tools are described which could be used for identification, collection, examination, and analysis, and reporting of digital evidence. Analysis of digital evidence includes disk imaging, memory capture, web browser history analysis, and various logs, etc., found in the system or network. Keywords: Digital Forensics, Computer Forensics, Cybercrime, Computer Crime, Computer Tools.
Forensic Aspects of Abrus precatorius for Medicine and Toxicological Contemplations
by Sheetal Gahlyan
Abrus precatorius is the most prominent medicinal plant worldwide. Despite its medicinal value, it is highly poisonous to humans as well as animals. About every part of the plant is used for several medical purposes and almost all the parts are toxic. Seeds are the most poisonous part of plants and contain the active constituent i.e. Abrin which is highly responsible for the toxicity in individuals. It is widely used for the occultist purpose as well. Time for an antidote, proper treatment, and manner of detoxification are the key points to cure the Abrus precatorius poisoning. Manner of treatment is based on the symptoms noticed after poisoning. This review successfully discusses the morphological, toxicological, treatment, analysis (including extraction and detection) and therapeutic uses as well as Abrus precatorius for forensic considerations. Keywords: Abrin, Seeds, Toxicity, Anti-abrin, Analysis, Biological Matrices, Therapeutic Potential.
Extraction and Identification of Pesticide Residue in Fruits and Vegetable Samples for Forensic Consideration
by Ruchika Dwivedi, Dr. Munish Mishra
Various pesticides and insecticides have been used in every region of most of the countries in the world to manage and mitigate different agricultural pests. Predicament of the presence of pesticide residues in fruits and vegetables is the major concern to the staid matter of individual health and wellbeing. The present study entitled “Extraction and Identification of Pesticide residue in Fruits and Vegetable samples for Forensic consideration” was carried out with an objective to analyze and identify pesticide residue in fruits and vegetables by using QuEChERS extraction procedure and TLC method. 4 Fruits (banana, apple, papaya, and guava) and 6 vegetable (eggplant, carrot, bell pepper, potato, okra, cauliflower) sample were collected from vegetable market of Allahabad. Extraction of pesticides was done by using QuEChERS extraction procedure and analyzed for qualitative determination of the presence of pesticides on samples by using thin-layer chromatography. Result revealed that 90% of samples were positively contaminated with as a minimum of one or more pesticide. The findings of the study might help in extending awareness to the farmers and local people about pesticides and their hazardous effects on humans. Whereas the methodology might be useful to the analyst working in the particular field as well as a forensic laboratory for rapid extraction of residues from biological and non-biological samples and to overcome the major issue of all the forensic laboratories i.e. pendency of cases.
