This document discusses drug abuse trends from the perspective of a retired drug recognition expert. It notes that legal prescription drugs, including opioids, sedatives, stimulants, and anti-convulsants, are commonly abused. These drugs are abused for their psychoactive effects like euphoria, sedation, and increased energy. While many prescription drugs were not initially intended for abuse, high doses or alternative routes of administration can result in abuse potential. The document cautions that prevalence of abuse is difficult to determine but provides examples of medications commonly abused based on reports from treatment centers and prisons.

In 2009, the Texas A&M Transportation Institute (TTI) added a one-of-a-kind Visibility Research Laboratory to its collection
of world class research facilities. The laboratory is located in the Institute’s State Headquarters and Research Building in the Research Park at Texas A&M University in College Station, Texas. The laboratory features a 125-foot-long corridor that is used to test retroreflective materials and coatings, lights and other technologies designed to provide nighttime visibility for
highway drivers.
What is Truck Platooning?
Level 2 truck platooning extends radar and vehicle-to-vehicle, communications-based, cooperative-adaptive cruise control using precise automated lateral and longitudinal vehicle control to maintain a tight formation of vehicles with short following distances. A manually driven truck leads a platoon, allowing the driver(s) of the following truck(s) to disengage from driving tasks and monitor system performance. Level 1 truck platooning has demonstrated the potential for significant fuel savings, enhanced mobility and associated emissions reductions from platooning vehicles. Level 2 automation may increase these benefits while reducing driver workload and increasing safety.
The Transportation Revenue Estimator and Needs Determination System (TRENDS) model funded by the Texas Department of Transportation is designed to provide transportation planners, policy makers and the public with a tool to forecast transportation revenues and expenses based on a user-defined level of investment at both the state and local
level. The user, through interactive windows, can control a number of variables related to assumptions regarding statewide transportation needs, population growth rates, fuel efficiency,
federal reimbursement rates, inflation rates, taxes, fees and other elements. The output is a set of tables and graphs showing a forecast of revenues, expenditures and fund balances for each year of the analysis period based on the
user-defined assumptions. The TRENDS model also includes a local option sub-model for each of Texas’ 25 Metropolitan Planning Organizations. Through the local option model the user can analyze changes in local revenues by creating
or adjusting a local fuel tax, local vehicle miles traveled tax, local vehicle registration fee or the local fuel efficiency rates.
The Travel Forecasting Program at the Texas A&M Transportation Institute (TTI) supports and assists public agencies in the development, implementation and application of
current and emerging technologies in travel demand forecasting.
The purpose of travel forecasting is to help transportation
decision makers, at the local and state levels, improve the overall function of the transportation system. Program staff members accomplish this by developing travel models that predict future transportation patterns based on many variables. The variables used by program staff include comprehensive travel survey data, U.S. Census data, current and projected socio-demographic data, existing and projected transportation system data, and current traffic data.
The Texas A&M Transportation Institute (TTI) Transportation Planning Program conducts research on travel surveys, travel behavior and related data collection methods to support travel models, policy, and air quality analyses. Program researchers have expertise in travel data collection methods and technologies; survey design and sampling, data analysis and interpretation; demographic data preparation for modeling; and corridor management and preservation.
The Texas A&M Transportation Institute (TTI) Transit
Mobility Program provides research and technology transfer expertise in all aspects of public transportation planning, management and operations. Program researchers bring a combination of direct operational skills in all bus and rail modes and nationwide research experience with metropolitan, urban and rural transit systems. Research projects result in practical, actionable recommendations for enhancing transit access, efficiency, effectiveness, safety and funding sustainability. Transit Mobility Program staff are adept at facilitating multi-agency groups in the development of shared transportation objectives, innovative strategies and coordinated services.
The TTI Center for Transportation Safety is home to a Realtime Technologies, Inc. (RTI) driving simulator that provides measurements of drivers’ responses to roadway situations, in-vehicle technologies, and driving-related tasks. RTI’s
SimCreator® and SimVista® software tools provide a library of different roadway cross-sections and interchanges, as well as a variety of roadway objects, buildings, and ambient traffic. In addition, custom roadway tiles can be programmed to match a specific roadway segment. This allows for in-house development of a wide range of rural and urban roadway scenarios, making it possible to inexpensively test multiple variations and placements of roadway devices or in-vehicle
signals and displays. Using the driving simulator, researchers can test a wider variety of roadway geometries and traffic conditions than are typically possible in a test-track study or fiscally practical in a field study.
The Texas A&M Transportation Institute’s (TTI) Sediment and
Erosion Control Laboratory (SEC Lab) provides the transportation industry with a research and performance
evaluation program for roadside environmental management. Research at the SEC Lab includes stormwater quality improvement, erosion and sediment control, and vegetation
establishment and management.
The Texas A&M University System is creating a new paradigm for the future of applied research, technology development and education. The 2,000 acre RELLIS Campus is conveniently located just 8 miles/15 minutes from Texas A&M University’s main campus. This location has long been a place where Texas A&M has conducted world-class research, technology development and workforce training in areas such as vehicle safety, traffic engineering, law enforcement training, biological materials processing, robotics and unmanned aerial systems.
Freight and passenger rail is a critical component of our nation’s
transportation system. Texas A&M Transportation Institute’s

remains active in exploring the future of rail through a variety
of research activities.
Public scrutiny and agency accountability are at an all-time
high. Agencies are looking for a better understanding of the issues that are important to their customers. In an era of strained financial resources, it is necessary to order priorities that are important to the people that support the transportation system through taxes and fees. The Public Engagement Planning (PEP) program at the Texas A&M Transportation
Institute (TTI) provides research innovations and coordinated support to sponsors in the areas of public engagement planning and public opinion research.
The Texas A&M Transportation Institute (TTI) was asked by the Texas Department of Transportation (TxDOT) to assist in the application and refinement of prior research to accomplish some key goals during the reconstruction of the I-35 corridor from Hillsboro to Salado (90 miles total). Currently, TxDOT is conducting 10 construction projects along this corridor. More than 30 million drivers, including travelers, shippers and intercity commuters, use the corridor each year.
Intelligent transportation systems (ITS) include a broad range of services and technology solutions that provide and manage information to improve the safety, efficiency and performance of our transportation network.
Researchers design and implement experiments with human subjects (including field and simulator studies) and survey subjects to identify driver safety issues, such as those related to traffic control devices, distraction and fatigue. TTI’s experimental psychologists and industrial engineers have conducted numerous studies related to driver response to roadway geometric design; visibility and driver comprehension of traffic control devices; driver distraction; and automotive adaptive equipment for disabled drivers, older drivers and short-statured drivers.
The Human Factors Program is housed within the Center
for Transportation Safety at the Texas A&M Transportation
Institute (TTI). The goal of the program is to conduct basic and
applied research to measure driver performance and behavior
for varied driving situations, vehicle characteristics and roadway
environments. Researchers design and implement experiments with human subjects (including field and simulator studies) and survey subjects to identify driver safety issues, such as those related to traffic control devices, distraction and fatigue.

In 2020, the Ministry of Home Affairs established a committee led by Prof. (Dr.) Ranbir Singh, former Vice Chancellor of National Law University (NLU), Delhi. This committee was tasked with reviewing the three codes of criminal law. The primary objective of the committee was to propose comprehensive reforms to the country’s criminal laws in a manner that is both principled and effective.
The committee’s focus was on ensuring the safety and security of individuals, communities, and the nation as a whole. Throughout its deliberations, the committee aimed to uphold constitutional values such as justice, dignity, and the intrinsic value of each individual. Their goal was to recommend amendments to the criminal laws that align with these values and priorities.
Subsequently, in February, the committee successfully submitted its recommendations regarding amendments to the criminal law. These recommendations are intended to serve as a foundation for enhancing the current legal framework, promoting safety and security, and upholding the constitutional principles of justice, dignity, and the inherent worth of every individual.

Lifting the Corporate Veil. Power Point Presentationseri bangash
"Lifting the Corporate Veil" is a legal concept that refers to the judicial act of disregarding the separate legal personality of a corporation or limited liability company (LLC). Normally, a corporation is considered a legal entity separate from its shareholders or members, meaning that the personal assets of shareholders or members are protected from the liabilities of the corporation. However, there are certain situations where courts may decide to "pierce" or "lift" the corporate veil, holding shareholders or members personally liable for the debts or actions of the corporation.
Here are some common scenarios in which courts might lift the corporate veil:
Fraud or Illegality: If shareholders or members use the corporate structure to perpetrate fraud, evade legal obligations, or engage in illegal activities, courts may disregard the corporate entity and hold those individuals personally liable.
Undercapitalization: If a corporation is formed with insufficient capital to conduct its intended business and meet its foreseeable liabilities, and this lack of capitalization results in harm to creditors or other parties, courts may lift the corporate veil to hold shareholders or members liable.
Failure to Observe Corporate Formalities: Corporations and LLCs are required to observe certain formalities, such as holding regular meetings, maintaining separate financial records, and avoiding commingling of personal and corporate assets. If these formalities are not observed and the corporate structure is used as a mere façade, courts may disregard the corporate entity.
Alter Ego: If there is such a unity of interest and ownership between the corporation and its shareholders or members that the separate personalities of the corporation and the individuals no longer exist, courts may treat the corporation as the alter ego of its owners and hold them personally liable.
Group Enterprises: In some cases, where multiple corporations are closely related or form part of a single economic unit, courts may pierce the corporate veil to achieve equity, particularly if one corporation's actions harm creditors or other stakeholders and the corporate structure is being used to shield culpable parties from liability.

Its objective is to provide lawyers with some background to understand what they can and cannot realistically expect from these products. This guide aims to give a reference point for small law practices in the EU
against which they can evaluate those classes of AI applications that are probably the most relevant for them.
3. Isaac Newton & the DRE
Newton’s First Law of Motion: An object will continue
to move at a constant velocity, unless acted upon by an
external force
Role of officers and prosecutors: the External Force
Behavior changes when…there’s consequences
Without consequences….behavior may not change
4. My Perspective
Law enforcement
Drug Recognition Expert
Distinguish between opinion and facts
Much based on real or anticipated court issues and
challenges
Prevalence not a primary topic
5. Approaches to DUI enforcement…
Alcohol and/or drugs
Impairment versus Biological
Impairment approach
Behavior emphasized
Officer skill in identifying impairment paramount
Toxicology supportive role
Biological approach
Emphasizes presence and levels
Toxicology definitive
5
6. Approaches to DUI enforcement…
US today
Impairment AND Biological
Reflected in laws
Basic DUI law prohibits DUI
Per se law prohibits a BAC & possibly Drugs
Drugs
Often zero tolerance for illegal drugs
Movement to specific blood nanogram levels
6
7. Prevalence issues
Prevalence
Proportion of a population with a given condition
Rapidly changes; Not accurately known
As Dr. Burns once remarked….
Each generation has to discover for itself the bad effects
Because we don’t see something today, doesn’t mean we
won’t see it tomorrow
Example: Deleting hallucinogens and inhalants suggested
“Chicken and the egg” discussion with labs
Continuous dialogue with labs a must
8. Golden Triangle of Abused Legal Drugs
1,000s of drugs
Abuse primarily of 3 of 7 DRE Drug Categories
“The Pills”
Central Nervous System Stimulants
E.g. Adderall, Provigil, etc.
CNS Depressants
Xanax, Zolpidem (Ambien), etc.
Narcotic Analgesics
Oxycodone, vicodin, methadone, etc.
New drug: Hyslinga ER (hydrocodone)
9. Hydrocodone ER
Recently approved by FDA
Purdue Pharma
Hysingla ER tablet
Abuse-deterrent properties
Turns into a gel when dissolved
Unlike Zohydro ER capsule
Schedule II
20 to 120 mg tablets
Duration 24 hours
Zohydro 12 hours
10. Which Drugs Abused?
• Those that In small amounts (depends on the drug!)…
• Alters mood
• Drugs of Abuse affect the Brain
– Psychoactive substances
– The Central Nervous System
– Means they cross the Blood-Brain Barrier (BBB)
• No CNS effects unlikely to be abused
• Can be “misused” however
Session IV - 10
11. Session IV - 11
Psychoactive
• A chemical that alters brain/body function
resulting in temporary changes:
– In Perception (sensory info)
– Mood (state of mind or emotion)
– Consciousness (feelings of awareness)
12. pagete@gmail.com

The Drugs of Abuse according to
DRE…
• A Categorization Schema NOT based
upon…
– Legality, such as scheduling
– Shared chemical structure
– Therapeutic uses, if any
13. pagete@gmail.com
13
DRE Categorization IS based upon the
premise that…
• Each category produces a PATTERN of
effects
– The signs and symptoms
– That is unique to the category
• A signature, not a fingerprint
14. DRE Drug Classification
Seven Drug Categories
Cross-abuse within category
Helpful in predicting drug use trends
Tolerant to one drug in a category
Likely tolerant to others in the category
15. Session IV - 15
Seven categories of Drugs
• Central Nervous
System Depressants
• CNS Stimulants
• Hallucinogens
• Dissociative
Anesthetics
• Narcotic
Analgesics
• Inhalants
• Cannabis
17. Why people use drugs?
Heroin conference presentation
Researchers on methadone
If on methadone, people won’t use heroin
Not consistent with my observations!
Researchers correct!
No biochemical reason to use heroin when using
methadone
EXCEPT……
18. Use, Under the Influence,
Impairment
Related, but not identical
Signs of use the same as signs of impairment?
Use: Signs and symptoms may be evidence of use
Under the Influence: Alcohol and/or drug causes
effects
Impairment: may not be by alcohol and/or drugs;
deterioration in ability to do something
19. Use, Under the Influence,
Impairment
What about the so-called “clinical signs?”
With a movement to statutory drug levels…
IMO will be increasingly important
Clinical signs (from DRE) ?
Info on “use” or exposure?
Or actual impairment?
HGN, VGN, Lack of Convergence?
Bloodshot eyes?
Pupil size issues?
Vital signs?

Alcohol v. Other Drugs
• Blessing and Curse of Alcohol!
• Alcohol has simple pharmacokinetics
– The “ins, arounds, changes, and outs”
– Zero order pharmacokinetics
– The exception! Not the rule
• Easy to study & measure
• All are familiar with alcohol
• The numbers relate (imperfectly) to
impairment
22. drugrecognitionexpert.c
22
Alcohol v. Other Drugs…
• Some of the problems with drugs…
– Complex pharmacokinetics
– First order pharmacokinetics
– Rate dependent on the amount
– Complex pharmacology
•Eg: Metabolites may be active
– Difficulty studying some drugs – on
humans
– Relationship between levels and
impairment more complex
23. Levels!
Big problem with drugs: Impairment
Interpretation of levels
In blood!
Example: Marijuana
If it’s in the brain
It’s not in the blood!
Impairment rising when blood level decreasing!
Poly-drugs complicates
24. Narcan issues
Nalozone
AKA the “Lazarus” Drug
Pure opioid antagonist
Reverses overdose from opioids!
If it works…possibly best evidence of drug influence!
Still positive blood test
Take away: If it works, the person was under the
influence of an opioid
Duration different however
25. Therapeutic Range issue
A defense?
Prosecution burden?
Timeline of use, influence, elimination
May be therapeutic level at time of blood draw
Not necessarily at time of use
Doesn’t mean no adverse effect
May even be intended effect
Ambien, for example
Therapeutic range of alcohol?
26. Withdrawal/Downside Issues
Drug wearing off
Effects are from lack of the drug
Alcohol example
Withdrawal
Hangovers AFTER drinking not during
Is withdrawal impairment?
As Driving with a Hangover
But…is driving with a hangover DUI?
“Spock logic” conundrum
Can one be DUI due to the absence of a drug?
27. Just because it’s legal…doesn’t
mean….
It was used appropriately
It was the individual’s Rx
The person wasn’t impaired
My opinion:
It’s uncommon to arrest someone for DUI for
appropriate use of a legal drug (non-alcohol)
Even rarer for the person to be prosecuted
28. Relationship to illegal drugs
ONDCP expressed surprise at Heroin increase
After cracking down on “pill mills” that distributed so-
called “pain pills”
Not a surprise to DREs
Understanding DRE categories an aid to anticipating
drug use trends
Limiting availability of one in a category
Leads to diversion to a different drug in the category
Alcohol example
29. Relationship to legal drugs (cont.)…
May even divert to OTC, neutraceuticals
Valerian root example
Overall….
When one drug is up, another goes down!
Profit motive a primary driver of this
Example:
Putting heroin in capsules and selling as vicodin,
etc.
Putting vicodin in capsule and selling as heroin
30. Statistics
Einstein:
Not everything that can be counted matters.
And not everything that matters can be counted
31. DRE Investigations
Miranda Issues
Two-pronged test: Custody and Accusatory
questions
DRE agencies vary in policy
Generally, the earlier the better
Not part of the standardized procedure
32. Questioning the suspect
Focus on the elements of the crime
Usually just driving, abilities impaired, due to presence
of alcohol and/or drugs
Topics:
Naïve user?
Absorption issues
When ate
Doctor’s, Pharmacist, HCP advise
Poly drugs, including alcohol
33. Questioning the suspect (cont.)…
When taken/ingested
How does it make you feel?
How did you feel today?
You felt some effects when driving?
On a scale of zero to 10…
Zero being completely sober
10 being the most wasted you’ve ever been
Where are you now?
Where were you when driving?
34. Poly Drugs….
Complicates everything!
Search for meaningful Levels
Detection
Signs and symptoms
Why poly drugs?
Duration issues
Avoid the “crash”
Strengthen effect
Add new effect
36. Biological specimen…
No perfect sample
Gene Adler: “Blood and urine are both scientifically and
legally defensible specimens.”
Time-line issues…
Use
Drive
Police observation
Police Investigation
Transport
DRE
Sample taken
37. Biological sample (cont.)
The closer in time to the driving the better!
The best sample is all of them!
12th DRE Step – toxicology – doesn’t mean it’s the last
thing done!
38. Why Rx and some OTC drugs
abused
Abuse may not become evident for years after the
introduction of the drug
Abused for:
Sedative Properties (CNS Depressants)
Stimulant Properties (CNS Stimulants
Euphoric Effects (a “buzz”)
Dissociative/Hallucinogenic Effects
39. Potential for Abuse
• Controlled substances well-known
• Also certain non-controlled Rx drugs
• And certain OTC medications
• Any substance that’s psychoactive may be abused
• If in a high dose or high blood/cerebrospinal fluid level

40. Potential for Abuse
Abuse defined: using a drug for a non-medical or
pleasurable purpose
Abuse potential of narcotic analgesics (opioids) well-
known
Abuse potential Not as well-known for other
substances
Some start off non-controlled
Controlled once abuse evident
Carisoprodol (Soma) as an example
41. How Big a Problem?
Incident unknown because of lack of formal reporting
mechanisms
Some evidence from DAWN
Increase in hospitalizations from
Diphenhydramine (Benadryl)
Muscle relaxants
Psychotherapeutic agents
Evidence from Penal institutions
quetiapine, gabapentin, bupropion, trihexyphenidyl (for
Parkinson’s), and tricyclics
Medication abuse among older folks
42. Kinds of substances abused
CNS activity a must!
Effects desired are:
Relaxation, sedation (CNS Depressants)
Intoxication, euphoria
Increased energy (CNS Stimulants)
Hallucinations
43. Abused for depressant effects…
antihistamines, quetiapine, olanzapine, tricyclics,
gabapentin, skeletal muscle relaxants, and clonidine
(catapres)
Clonidine: for HBP and ADHD; sympatholytic
44. Abused for stimulant effects…
pseudoephedrine, tranylcypromine, bupropion,
fluoxetine, and venlafaxine
47. Medication may be abused to…
Experience the “high” from the medication
To prolong the effect of another drug
Provide a new effect – a synergistic effect
Counter the bad effects of one drug with another
48. Abused by…
Taking much larger dose than recommended
Changing route of administration
E.G.: insufflating a drug
E.G.: snorting buproprion
49. Cough & Cold…

Pentazocine (Talwin) and tripelennamine
Heroin-like intoxication
Diphenhydramine
Commonly known as Benadryl, Sominex
Abused for sedative-like properties
Effect dopaminergic pathways
Possible cocaine-like intoxication in some
51. Anti-Psychotics
Primarily older anti-psychotics

Sedating, CNS effects
Usually high doses
Combined with other CNS depressants
52. Seroquel…
Quetiapine
Anti-psychotic
Treats bi-polar disorder
Abused for sedation effects
Also anxiolytic (stress reduction) effects
“Quell” a slang term
AKA “baby heroin”
Removed from many prison formularies
53. Anti-Depressants
Some have stimulant and sedating effects
Tranylcypromine (Parnate)
Amphetamine like chemical structure
Tricyclic Antidepressants (TCAs)
Elavil as example
Often abused with opioids
