While physical injury
cases can be decided without digging deeper into scientific details,
toxic tort cases require a somewhat more complex approach to come up
with a fair judgment. Namely, it requires the statement of a reliable
medical expert witness. Here are some basic facts about the technical
realm of toxic tort claims and litigation that every lawyer should
arm themselves with:

Forensic Toxicology: The Need for Expert Witnesses
Dealing
with mysterious criminal cases requires forensic
science
to obtain fact-based evidence. All evidence has to be carefully
examined by a forensic toxicologist, a professional who has vast
knowledge of chemicals and their effects on physical matter. A
forensic toxicologist in this scenario becomes an expert witness and
his opinion can serve either the defense or the prosecution.

Figuring out Alcohol Poisoning
Once in a while, it’s
good to have a drink with your friends; you bond and talk with them
over a few shots, and simply enjoy each other’s company. However,
time does fly when you’re having fun and it’s possible that you
would have downed several shots more than you think you had. Such
instances can result into alcohol poisoning, and if something bad
does happen, a forensic toxicology specialist will help uncover the
truth.

Prescription Drugs in Light of Forensic Toxicology
Medicine
has always utilized pharmaceuticals in the treatment of their
patients. Drug recommendation and administration are both part of the
complex web of patient treatment. Generally, these substances in
virtually all forms of matter are aimed to yield eradication of a
disease. If this were not possible, the drugs would at least relieve
the ailment's symptoms.

What is Hair Testing?
Hair
is made up of keratin, a strong structural protein that comprises
three parts, the medulla, the cortex, and the cuticle. Beyond its
anthropological and biological meaning, this biomaterial has the
ability to store what passes through the body. That’s why the
courts use hair testing as a way to remove a person from suspicion or
connect certain suspects with criminal activity. Forensic
toxicologists are the people responsible for the analyzing of hair
for the courts.

Facts About the Dangers of Lead Poisoning
Lead is one of the
naturally-occurring metals that can prove very poisonous to humans,
especially when ingested or inhaled over an extended period. Lead
buildup in the body could cause various illnesses including cancer
and even brain damage. What do you do when you suspect that someone
you know has been poisoned by this substance?
Lead poisoning is very
unlikely to be new; experts believe that mankind has been using lead
for more than 6,000 years. Children are at the highest risk of
contracting diseases from lead exposure because they are more
sensitive than adults and they usually put things in their mouths,
particularly objects that may be contaminated by lead dust.
If you suspect that you
or a loved one is suffering from lead poisoning, see a doctor
immediately. When lead poisoning tests prove positive and you decide
to file a case for investigation and penalty, you might as well seek
the help of a highly-qualified medical expert witness.
Consulting a reputable
toxicology
expert witness is necessary to obtaining a professional opinion
on causation. Toxicologists have extensive knowledge and experience
on the nature and effects of toxins and poisons including chemicals,
pharmaceutical products, metals, and alcohol.
As professionals,
toxicologists can conduct thorough analysis or scientific
investigation and present an unbiased report after research for
purposes of litigation. Through this method, the court will be able
to determine whether or not there is negligence on the part of the
defendant.

Forensic Toxicology Can Debunk the Poppy Defense
When
it comes to detecting substance abuse, urinalysis remains to be the
tool of choice by forensic toxicologists. Recent improvements in drug
tests may soon accurately separate positive cases of heroin use from
false-positive ones, wherein individuals have only ingested poppy
seeds and not taken an illegal drug. These false-positive cases have
presented problems to authorities because of the possibility that
drug users may only be using the “poppy seed defense” to their
advantage.
The
term relates to how people can test positive for heroin abuse simply
by consuming pastries made using poppy seeds. Depending on the
quantity of seeds consumed, a person may test positive even up to 60
hours after ingesting the food containing poppy seeds.
While
there are some claims that poppy seed ingestion do not make
false-positive results in hair tests, forensic specialists have
doubts as to its accuracy. This is why urinalysis remains the top
choice when it comes to detecting substance use.
Should
subsequent studies regarding the use of effective markers for street
heroin prove successful, forensic
toxicologists will be able to provide an expert opinion
regarding a person’s alleged heroin use based on the chemicals
found on the urine sample. Such professionals can help a defense or
plaintiff attorney with accurate medical assessments regarding the
sobriety or condition of the individual in question.

Why You Need a Toxicology Expert Witness
In a nutshell, death
investigation uses forensic toxicology to identify the cause of
death. In this discipline, toxicologists usually study the
concentration of substances ingested by a person and their effect to
the body. Blood and hair samples are frequently used to detect the
chemicals present in the system. In fact, a 10 ml blood sample is
enough to verify the presence of a toxic substance. When it comes to
hair samples, toxicologists would refer to the hair follicle as it is
useful in determining medium to long-term substance abuse.
A deceased person's
gastric contents may also show undigested substances that have been
ingested before death. It is also possible to come up with a rough
estimation on the time of death depending on the state of digestion
of stomach contents.
A toxicology expert
witness strengthens evidences when criminal cases are brought to
court. They provide a detailed analysis of the substances found
during the autopsy and even on the samples collected by the
investigators. The outcome of the case largely depends on how
accurate the interpretations are. Plaintiffs or defendants will have
to seek the services of a toxicology expert witness to have reliable
documentation needed for proper litigation. They may even ask the
toxicologist to provide testimony before the court.

What is Forensic Toxicology?
The early 1800s and early
1900s are usually referred to by era historians as the “golden age
of poisoning”. The incidence of poisoning was so high during the
said period that scientists became driven to find antidotes or
solutions, eventually giving birth the science of forensic
toxicology. The tasks of forensic toxicologists include the
examination of blood, tissue samples, and body fluids of a victim to
determine if the cause of death was due to drugs or other poisonous
substances.
Generally, forensic
toxicology is a discipline in forensic science that focuses on the
study of toxic substances. To be more specific, it involves the study
of drugs, alcohol, and poisons, and their absorption, distribution,
and effect to the human body. There are four disciplines under
forensic toxicology, namely death investigation toxicology, human
performance toxicology, doping control, and forensic workplace drug
testing.
Death investigation
toxicology focuses on identifying the role of alcohol, drugs, and
poison as the cause of death of some people, and is typically
practiced by pathologists and medical examiners. On the other hand,
human performance toxicology tackles the effects of alcohol and drugs
on the performance and behavior of humans.
Finally, doping control
is frequently applied in the world of competitive sports as it
assists in detecting the use of banned performance enhancing drugs by
athletes. Forensic workplace drug testing is used to ensure that
employees or workers are compliant with safety standards that
strictly prohibit the use and abuse of illegal drugs or substances.

Toxicology Expert Witness Can Affect Case Outcome
In a companion case of
Exxon Mobil v. Ford et al, both sides must have been nervous when a
toxicology expert witness testified. After all, $1.65 billion in
compensation was at stake. Although the toxicology expert was just
one of the many experts called at that time, his testimony surely
have contributed to the outcome of the case.
As a background: dozens
of Jacksonville, MD households had sued Exxon Mobil for an undetected
gas leak from one of its service stations that contaminated water
wells in the area. The households filed two lawsuits against Exxon
Mobil, including the $1.65 billion companion case. After the oil
company lost both cases, they elevated them to the Maryland Court of
Appeals.
In a legal case involving
chemicals, a toxicology expert is generally called in to support or
refute any evidence presented. He or she examines affected
individuals, reviews medical reports, and works with legal
authorities, among others. In this case, the toxicology expert
recommended annual tests for certain ailments that costs up to $2,000
per year for each respondent.
However, the Maryland
Court of Appeals also found that the “expert testimony generalized
that all Respondents faced a significantly increased risk of
developing a future disease, without providing individual assessments
of any Respondent.” That finding partly contributed to the Court’s
reversing the decision of the $1.65 billion companion case and
sending it back to the lower court for a new trial.

Toxic Tort Cases: Importance of Toxicology Experts
Toxicology expert
witnesses are board-certified professionals who are called to testify
in court for a wide range of cases involving medical toxicology,
environmental toxicology, poisoning, substance abuse, and nutritional
diseases to name a few. They are knowledgeable in many disciplines
and have a proven track record in dealing with the aforementioned
cases.
One of the most common
cases handled by these experts is toxic tort, which is an illness or
an injury that occurs when an individual comes in contact with a
toxic substance such as asbestos, toxic mold, solvents, pesticides,
and even pharmaceutical drugs. A lawyer specializing in toxic court
cases conducts research and gathers the necessary data to present in
court, and will most likely seek and consult a toxicology expert
witness whose knowledge would enable him to provide a clear and
reliable testimony.
A reliable toxicology
expert witness should practice environmental, occupational, forensic,
or medical toxicology. He or she should be able to evaluate and
testify for cases that involve carbon monoxide poisoning, adverse
drug reactions, substance abuse, and outbreaks. Knowledge in fields
such as public health, emergency medicine, industrial hygiene, and
health sciences is also necessary. Apart from gaining experience
after handling several toxicology cases, a toxicology expert witness
should also be able to testify and give his expert opinion without
bias.

A Quick Guide to Proving Death By Poison
Death
by poisoning can be the result of a crime, whether the poisoning was done
intentionally or accidentally. In intentional cases, investigators must prove
that another person or entity deliberately caused the administration of poison
to the victim's body. If the poisoning was accidental, the person or entity
behind the victim's unintended exposure to the poison will need to account for
their negligence.
Those
prosecuting a death
by poisoning case need to establish, beyond reasonable doubt, that the
death was caused by a poison. Investigators then need to collect evidence to
show that another party was responsible for the poisoning. From the evidence
they gather, the investigators then need to determine whether the poisoning was
done intentionally or accidentally; and in the case of the latter, they have to
further evaluate if negligence was involved.
In
establishing that the cause of the death was poison, the expertise of forensic
toxicologists is often required. They examine the victim's body to find traces
of the poison, identify the kind of poison involved, and determine that the
amount of poison ingested by the victim was sufficient to cause death. The
poison has to be present in the victim's circulation system and/or body organs.
Its presence in the victim's gastrointestinal tract alone does not prove that
the death was caused by the poison. It has to be shown that the poisonous
element has penetrated through the person's intestinal walls and into the
circulation system, which carried the poison to other parts of the body.
