Preventionists-Key to the Health and Welfare of Americans
Opioids crisis continues, but with evidence for positive effects of government
efforts in partnership with states, communities, organizations
Ongoing work of preventionists, clinicians, peers, first responders, faith-based
groups, volunteers, families
Major decline in heroin initiates in 2017
Large increases in naloxone distribution, overdose reversals
Prevention becomes even more important as we watch the unfolding story of the
impact of substance use on American communities
Preventionists: the first line in addressing the risks presented by substance use in
our communities
Increased focus on potential harms of substances
Raise awareness of risks with substance use
Community outreach to youth as well as adults
3
Substances of Increasing Importance: Marijuana, Kratom
and E-cigarettes (Nicotine)
Marijuana/cannabis:
Increasing prevalence of use
Increasing understanding of risks associated with use
Public lack of information on these risks
Opioids Issues:
Fentanyl-Contaminated Cocaine
Kratom
Botanical that at low doses produce stimulation and at higher doses produce opioid
effects
Potential for physical dependence and opioid-type effects/toxicities
Marketed in Western countries and increasing use/toxicities being reported
E-cigarettes
Vaping: heating and aerosolizing nicotine for inhalation
Nicotine is addictive and has adverse health effects
In 2017 e-cigs were the most commonly used nicotine product among high (11.7%;
1.73 million) and middle (3.3%; 0.39 million) school students.
4
Marijuana: The Issue
Marijuana is rapidly becoming more widely available in the U.S.
33 states: allow medical marijuana with reduced penalties for
possession; 9 states plus DC have legalized recreational use
Huge and profitable industry that markets heavily with health
claims that have little to no basis and which have had virtually
no counter arguments put forward until the present time
Numerous forms: smoked, edibles, oil for vaping, lotions,
transdermal patches
5
Marijuana: The Issue
Increasing potency of marijuana:
THC content: 3.8% (1990s) increased to 12.2% (2014)
Average MJ extract has THC levels at > 50%
THC: component responsible for euphoria/intoxication
Can also produce anxiety, agitation, paranoia, and psychosis
Responsible for addiction liability with estimates that 10-20% of
users will develop a use disorder (Volkow ND et al. 2016)
Declining CBD content in currently available MJ
Not thought to be addictive
May reduce psychosis
Medical value: FDA approved for certain seizure disorders (Ehsoly MA et al. 2016)

PERSISTENT CANNABIS (MARIJUANA) USE DISORDER
LINKED TO SIGNIFICANT IQ DROP
BETWEEN CHILDHOOD AND MIDLIFE
Source: Meier MH et al., PNAS Early Edition 2012
Followed 1,037 individuals from birth to age 38.
Tested marijuana use and disorders at 18, 21, 26, 32 and 38 years of
age.
Tested for IQ at ages 13 and 38
All groups started with roughly
equivalent IQ scores at age 13
By age 38, those who were
diagnosed with cannabis
dependence in 3 study waves
(the most persistent
users of cannabis) had lost nearly
6 IQ points by the age of 38
There was a consistent dose-
response relationship across the
groups

Adverse outcomes linked to marijuana use by youth:
Poor school performance and increased drop out rates
Chronic use in adolescence has been linked to decline in IQ that
may not recover with cessation (Meier et al. 2012)
Marijuana use in adolescence is associated with an increased risk
for later psychotic disorder in adulthood (D’Souza, et al. 2016)
Marijuana use linked to earlier onset of psychosis in youth known
to be at risk for schizophrenia (McHugh, et al. 2017)
Summary: Consequences of Marijuana Use
Acute, intoxicating effects of marijuana:
Distorts perception; poor judgment and poor decision making
(e.g.: unprotected sex, driving while intoxicated)
Impairment in balance and coordination (important to injury risk
in activities such as driving, sports)
Difficulty with attention, concentration, and problem solving
Difficulty with learning and memory (immediate and recall)
30
Marijuana Use: Health Consequences
Significant numbers who try marijuana will become addicted
(Lopez-Quintero, et al. 2011)

Evidence for some medical value of some components
CBD and seizure disorder (Dravet’s syndrome and Lennox-Gastaut syndrome)
THC products for wasting illnesses and appetite production
Medications must have undergone substantial research to answer critical
questions before getting to market and widespread use in humans:
Isolation of single components; manufacture processes
Delivery mechanism
Pharmacokinetics/pharmacodynamics
Dose-response relationships (e.g.: doubling a dose may or may not double
the effect)
Therapeutic range
Adverse events: what are they and how best to avoid/address should they
occur?
These types of studies would be difficult for marijuana because there are so
many components
31
32
Where Do We Go From Here?
Government has a responsibility to inform Americans of the risks of marijuana use
People need to be able to make informed choices
States should consider short and long term issues related to marijuana
Tax revenue
Societal costs
Government costs
Major Issue to Consider: Marijuana has gotten ahead of regulation
How do we define intoxication?
What are the ‘legal limits’ of use (equivalent to BAC)
How should marijuana sales centers be regulated (should we better control the opening of marijuana
sales locations?)
Should warning labels be required on marijuana products?
How do we assure that underage sales are not occurring? (as with tobacco products, for example)
Should people be allowed to openly use in public?
Should people be allowed to use and operate motor vehicles?
What are the penalties?

New Stimulant Toxicity: Fentanyl-Contaminated Cocaine
Cocaine laced with fentanyl:
7% of cocaine seized in New England in 2017 was contaminated with fentanyl
Connecticut: deaths involving fentanyl-laced cocaine up 420% in last 3 years
Reported increases in deaths in NYC, PA, MA, NJ, OH, CA
https://www.ncadd.org/blogs/in-the-news/cocaine-laced-with-fentanyl-causing-growing-number-of-deaths
Why?
Poor quality control in packaging?
High Risk Groups:
Primary cocaine users
Opioid users may use cocaine to counteract sedation/intensify effect of opioid
Underscores the need to warn the public and provide treatment for cocaine use disorders
Epidemic is not just about opioid addiction
Cocaine users lack opioid tolerance: fentanyl overdose/death more likely
Naloxone
Discourage use alone

Kratom
Kratom is a tropical tree (Mitragyna speciose) native to Southeast Asia, used
traditionally to combat fatigue and improve work productivity among farm
populations in Southeast Asia
Has recently become popular as a novel psychoactive substance in Western
countries (Cinosi et al, 2015).
FDA is concerned that kratom, which affects the same opioid brain receptors as
morphine, appears to have properties that expose users to the risks of addiction,
abuse, and dependence
Currently, there are no FDA-approved uses for kratom, and the agency
has received concerning reports about its safety
35
35
Kratom preparations contain varying amounts of several
phytochemicals, making their pharmacological and
toxicological evaluation unique and difficult.
More than 20 alkaloids in kratom have been identified in
the laboratory.
Mitragynine is classified as a kappa-opioid receptor agonist
and is roughly 13 times more potent than morphine.
Mitragynine/OH-mitragynine thought to be responsible for
the opioid-like effects.

Kratom: How Used
37
The effects of kratom in humans are dose-dependent:
Small doses produce stimulatory effects resembling
the stimulant effect of drugs such as cocaine or
amphetamines.
Larger dosages associated with sedative-narcotic,
pain reducing effects that resemble drugs such as
opiates.
Regular kratom use is associated with addictive
disorders, as evidenced by craving and compulsive
use. Opioid withdrawal symptoms upon cessation.

An anonymous online survey was conducted in October 2016 of 10,000 current
kratom users through available social media and from the American Kratom
Association (https://speciosa.org/home/ )
8,049 respondents completed the survey.
Findings:
Kratom was primarily used by a middle-aged (31-50 years) males (56.91%) with
income $35,000 or higher with private insurance (61.31%).
Kratom was used to self-treat pain (68%) and emotional or mental conditions
(66%) and for withdrawal symptoms associated with prescription opioid use.
Subjects reported dose-dependent nausea and constipation with high doses
(5g) and with and frequent dosing (Q22 doses/wk).

Source: CDC SUDORS Overdose Death Data
From July 2016 to June 2017, 25 fatal overdoses involving
kratom across 8 CDC SUDORS states were identified
Caution: testing of kratom is not uniform thus these numbers are underestimates
In 2017, the Food and Drug
Administration (FDA) began
issuing a series of warnings
about kratom and has now
identified at least 44 deaths
related to its use.
Most kratom associated deaths
appeared to have resulted from
adulterated products or taking
kratom along with other potent
substances.
41
Kratom has gained popularity for its euphoric effects and is being popularized as a
safe herbal product capable of giving a “legal” high (Swogger et al., 2015), and as an
alternative to other sedative and stimulant type drugs (Warner et al., 2016).
Reports of physical dependence on kratom in Western nations emerge from case
reports from the UK (Boyer et al., 2008, McWhirter and Morris, 2010), Germany (Kapp et al., 2011) and the
US (Dorman et al., 2014, Nelsen et al., 2010, Forrester, 2013, Sheleg and Collins, 2011).
It can be surmised that given the large and growing number of internet purchase
sites for kratom (cited in Cinosi et al., 2015), addiction to kratom is also likely to be growing
in the Western countries.
No treatment specific for kratom addiction available

United Kingdom
International Status of Kratom
Scheduling under consideration in U.S.
On November 14, 2017, the FDA issued a public health advisory related to
mounting concerns regarding the risks associated with kratom and reported
deaths with use.
43
Kratom is a recognized emerging public health threat (MMWR. July 29, 2016;65(29):748Y749)
People need to understand that ‘‘legal’’ and ‘‘available’’ are not the same as
‘‘safe.’’
In the West, kratom has been valued for its analgesic effects and to aid in
managing opioid withdrawal. However, some of these individual attempts
have resulted in cases of toxicity and fatalities.
Physicians should be aware of these herbal supplements and potential
toxicity or withdrawal effects in patients including in newborns which cannot
be picked up by the standard toxicology screen (Davidson et al, 2018).
Preventionists should be aware of this drug and work with their communities
raising awareness, providing education about effects and risks.

Adverse Health Effects of Nicotine
Nicotine exposure during adolescence can result in addiction.
Nicotine can harm the developing adolescent brain.
Nicotine delivered by e-cigarettes during pregnancy can result
in multiple adverse consequences, including sudden infant
death syndrome, and could result in altered corpus callosum,
deficits in auditory processing, and obesity.
Ingestion of e-cigarette liquids containing nicotine can cause
acute toxicity and possibly death if the contents of refill
cartridges or bottles containing nicotine are consumed.

E-cigarette Adverse Health Effects
E-cigarettes expose users to several chemicals, in addition to
nicotine: heavy metals (chromium, lead, manganese, nickel and
zinc), arsenic, volatile organic compounds (propylene glycol or
glycerol), all known to have adverse health effects.
The health effects and potentially harmful effects of doses of
heated and aerosolized constituents of e-cigarette liquids,
including solvents, flavorants, and toxicants, are not completely
understood.
E-cigarettes can also be used to deliver other drugs, including
marijuana. In 2016, one-third of U.S. middle and high school
students who ever used e-cigarettes had used marijuana in e-
cigarettes.

The Surgeon General's Warning on Marijuana
The Surgeon General of the Public Health Service has issued the following warning on marijuana:
Marijuana use is a major public health problem in the United States. In the past 20 years, its' use has increased 30-fold; it estimated that more than a quarter of the
American population has used it. The age at which persons first use marijuana has decreased gradually to the junior high school years. Until recently, nearly 11% of
high school seniors used it, and although that figure has declined to 7%, its daily use still exceeds that of alcohol; more high school seniors use marijuana than smoke
cigarettes. In a recent study, 32% of those surveyed had used marijuana during the previous 30 days, while 25% had smoked tobacco.
On March 24, 1982, the Department of Health and Human Services submitted to Congress a report reviewing the consequences of marijuana use. Marijuana and
Health, 1982, ninth in a series, is primarily based on two recently conducted, comprehensive, scientific reviews by the Institute of Medicine of the National Academy
of Sciences, the Canadian Addiction Research Foundation, and the World Health Organization (WHO).
Both independent reviews corroborate the Public Health Service's findings of health hazards associated with marijuana use: Acute intoxication with marijuana
interferes with many aspects of mental functioning and has serious, acute effects on perception and skilled performance, such as driving and other complex tasks
involving judgement or fine motor skills.
Among the known or suspected chronic effects of marijuana are:
short-term memory impairment and slowness of learning.
impaired lung function similar to that found in cigarette smokers. Indications are that more serious effects, such as cancer and other lung disease, follow extended use.
decreased sperm count and sperm motility.
interference with ovulation and pre-natal development.
impaired immune response.
possible adverse effects on heart function.
by-products of marijuana remaining in body fat for several weeks, with unknown consequences. The storage of these by-products increases the possiblilties for
chronic, as well as residual, effects on performance, even after the acute reaction to the drug has worn off. Of special concern are the long-term developmental
effects in children and adolescents, who are particularly vulnerable to the drug's behavioral and psychological effects. The "amotivational syndrome," characterized
by a pattern of energy loss, diminished school performance, harmed parental relationships, and other behavorial disruptions, has been associated with prolonged
marijuana use by young persons. Although more research is required, recent national surveys report that 40% of heavy users experience some or all of those symptoms.
The Public Health Service concludes that marijuana has a broad range of psychological and biological effects, many of which are dangerous and
harmful to health, and it supports the major conclusion of the National Academy of Sciences' Institute of Medicine.
