Drugs are a included in many of the criminal justice cases in the US so the need to have well trained analysts is important as well as having correct equipment and tests to analysis the drugs properly. There are Scientific Working Groups for many of the different disciplines of forensic science, including drugs. The NAS Report has recently come out taking about what changes should be made in the forensic science arena. There is an every multiplying amount of drugs in the world because new ones are constantly being created so there is a long future for this section of forensic science. The ways of analyzing drugs and identifying them are microcrystalline tests, gas chromatography, mass spectrometry, and spectrophotometry. Microcrystalline tests are more specific than the color tests and is uses the polarizing microscope. Gas chromatography is when the sample is separated into its different components based on size and chemical structure. Mass spectrometry fragments the molecules in the sample and that pattern of fragmentation helps with the identification of the substance when compared to a known standard. Spectrophotometry identifies substances by measuring how it absorbs the different wavelengths of light including; UV, visual, and infrared. There are all used to decipher the chemicals compositions of the sample to determine what kind of drug is contained in the substance, including how pure the substance is as well. The Scientific Working Group for drugs is SWGDRUG. They set out guidelines for the professionals that practice in the drug analysis. Some of the guideline includes training and continuous training, sample schemes and procedure, and reporting to name a few. The training guideline set out what you have to s... ... middle of paper ... ...erent drugs as being analyzed all the time. With technological advances identification is getting easier and more precise. The vast multitude of drugs will keep this kind of analysis alive for decades to come. Most sections of forensic science have a Scientific Working Group that sets guidelines and according to the NAS Report the SWGDRUG sets impeccable standards and if they are followed should produce actuate and reliable results.

Hello, my fellow students; today I want to take the opportunity to inform you all about my major; which is forensic and why it is important to the criminal justice system. Many people have asked me; what is forensic and they often get it confused with TV shows like CSI Miami or NCIS; however, forensics is more than what you see on TV. So what is forensics; simply put, forensics is the application of science to the criminal and civil laws that are enforced by the law. It involves other courses like biology, chemistry, and physics. Most people have a misconception on how forensics works and this is called the CSI effect; however, for the sake of this class, I am going to focus on a very important cold case called the JonBenet Ramsey case.
Therefore, the criminal justice system relies on other nonscientific means that are not accepted or clear. Many of forensic methods have implemented in research when looking for evidence, but the methods that are not scientific and have little or anything to do with science. The result of false evidence by other means leads to false testimony by a forensic analyst. Another issue with forensic errors is that it is a challenge to find a defense expert (Giannelli, 2011). Defense experts are required to help the defense attorneys defend and breakdown all of the doubts in the prosecutors scientific findings in criminal cases. Scientific information is integral in a criminal prosecution, and a defense attorney needs to have an expert to assist he/she in discrediting the prosecution (Giannelli,

...ogy to become more important than it has in the past. The term forensic toxicology has been identified as the examination of toxic substances in human tissues, organs, and body fluids that may have contributed or caused death to an individual (Tilstone, Savage, Clark, 2006). Although forensic toxicology is concerned with what toxic substances contributed or caused death to an individual, it also plays a major role in simple drug testing that doesn’t involve death whether it be drug screening for future employees or even testing which chemicals were involved in sexual assault cases. Regardless of the situation, a forensic toxicologist is involved with determining toxins in the body. Without the use of forensic toxicology, there would be a major hole in forensic science and would make it more difficult for determining causes and times of death in many sorts of cases.
In today’s time, modern Crime Scene Investigation has increased rapidly. From throughout the late 1900’s and in the early 2000’s (Taylor 1). For all of the evidence that they find, a solid foundation has formed over the thousands of years of Crime Scene
Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
The transitional growth in the forensic science sector has not been without challenges. Though the world has experienced increased capabilities and scientific knowledge, which has led to faster investigations and results, many forensic experts have argued that forensic laboratory testing, in the light of 21st century technological advancements, is yet to meet the expected rate in quick available testing and analysis (Mennell & Shaw, 2006). This is with respect to the growing rate of crime and the high demand of quick crime scene testing and analysis. In the science of crime scene, analysis and interpretation of evidence is majorly dependent on forensic science, highlighting the change in the role of forensic sciences (Tjin-A-Tsoi, 2013). In the business of forensic science, time is beginning to play important role in the evidence testing and analysis which is becoming crucial in reducing ...
Forensic toxicologists employ a large number of analytical techniques to determine the drugs or poisons relevant to an investigation; the capacity of a laboratory to conduct routine toxicological analysis varies depending upon equipment, technical capability and analyst experience. When needed, there are specialty toxicology labs that can test for almost any potential toxin or metabolite in almost every kind of post-mortem sample. A laboratory should be accredited to perform the analytical work and must be subject to regular inspections. This will ensure that laboratories can reproduce accurate and reliable results for investigations. All laboratory tests conform to standard operating procedures, results are confirmed to meet standards, and reported results are peer reviewed by a second toxicologist before being released. Even so, we still use methods that Gettler used in his
Forensic science has now been recognized as an important part of the law enforcement team to help solve crimes and cold cases. The advances in technology are being used each day and we must continue to strive to develop better advances in this field. The recent discovery of using DNA in criminal cases has helped not only positively identify the suspect, but it has helped exonerate hundreds of innocent individuals. “With new advances in police technology and computer science, crime scene investigation and forensic science will only become more precise as we head into the future.” (Roufa, 2017) Forensic science and evidence helps law enforcement officials solve crimes through the collection, preservation and analysis of evidence. By having a mobile crime laboratory, the scene gets processed quicker and more efficiently. Forensic science will only grow in the future to be a benefit for the criminal justice

Nearly every strand of hair, semblance of a footprint, and notch in the pavement left at the scene of a crime has the potential to be the critical point of affirmation that changes everything. Because of this, forensic biologists must arrive at the scene ready to collect any number of diverse traces of evidence. Tools of the trade include blood collection kits, sifting screens, glass vials, forensic light sources, brushes, and cameras (Equipment Needed for Crime Scene Investigation, n.d.). Back at the lab, equipment utilized to examine the evidence includes microscopes, centrifuges, chemical developers, and x-ray fluorescence (A Simplified Guide to Forensic Science, n.d.).
Forensic science has exploited advances in technology in order to develop new and more reliable methods of crime solving. In the past half-century, biotechnology has allowed for the creation of DNA technology and bioinformatics as DNA evidence is presented more in court now than in previous years. Other forensic methods have also advanced as new information has come to light and databases have been created allowing for evidence identification to become faster, easier, and more efficient. Just as the technology we use every day is still evolving, so is the technology used in forensic science, allowing for the emergence of new methods, techniques and important information to the crime solving universe of police stations and government agencies like the FBI.
With the advancement of different technologies, this could cause future prospects and challenges for forensic investigators and or scientists. One would believe that new technology would make solveing crimes for forensic scientist or investigators easier and quicker. However, with the advancement of technology comes the advancement of a criminal’s knowledge. Due to this fact, criminals may be more aware of not leaving behind fingerprints, bodily fluids, hair, blood, and or identification, causing it to be harder for forensic investigators to track and locate the suspect of the crime. Even though technology would be more advanced, forensic scientist and investigators might still face challenges of solving the crime, causing them to have to be more consistent with their different
