EDUCATIONAL OBJECTIVES After attending this presentation, participants will be able to describe how a person’s health is affected by:
SOCIAL DETERMINANTS OF HEALTH OF PWUD
SOCIAL DETERMINANTS OF HEALTH OF PWUD
• Bias and stigma in healthcare
• Nearly all participants endorsed
• Explicit Judgement, Minimizing, Stereotyped, Involvement of hospital security
• Poor pain control and denial of controlled medications that were prescribed
outpatient (benzos)
• Inadequate withdrawal management
• Restrictions, not being able to leave the floor (reminiscent of incarceration
SOCIAL DETERMINANTS OF HEALTH OF PWUD• Incarceration
Evelyn J. Patterson, 2013: The Dose–Response of Time Served in Prison on Mortality: New York State, 1989–2003 American Journal of Public Health 103, 523_528, https://doi.org/10.2105/AJPH.2012.301148
“2-year decline in life expectancy for each year served in prison”
SOCIAL DETERMINANTS OF HEALTH OF PWUD• Drugs effect on motivation
• Hygiene (dental, wound care)
• Preventative health maintenance
• Interactions with healthcare
• “No-Showed” for showing up late
• Cravings can be a factor in hospital AMA discharges
• Malnutrition
• Difficulty affording food
• May not feel hungry
• Ethanol itself is calorie dense (7.1 kCal per gram)
• May lead to complications
• Refeeding syndrome
SOCIAL DETERMINANTS OF HEALTH OF PWUD• Infectious Disease
• Housing related (ex. Tuberculosis)
• STDs/HIV
• Inconsistent condom use
• Impairment
• Motivation
• Rape, sexual assault, coercion, and exploitation
• A study of female sex workers found that substance use
was linked with violence and coercive condom negotiation
from clients
SOCIAL DETERMINANTS OF HEALTH OF PWUD• Traumatic injury
• MVA – in 2015 29% of MVA fatalities were alcohol related
• Violence
• Substances don’t “cause” violence; most PWUD are non-violent
• Things like disinhibition, paranoia, psychosis, may play a role in
violence
ROUTES OF ADMINISTRATION - INSUFFLATION

treatment. International dental journal. 55. 365-9. 10.1111/j.1875-595X.2005.tb00047.x.
ROUTES OF ADMINISTRATION - INHALATION• Toxic Leukoencephalopathy
• “Smoking” Heroin off of foil (chasing the dragon)
• Chemical process is pyrolysis; the heroin pyrolysate is inhaled
• Spongiform Leukoencephalopathy – myelin sheath develops
intracytoplasmic vacuoles → neuronal loss and gliosis
• Symptoms can progress over hours to weeks (or months)
• Ataxia and speech difficulties → EPS, spastic paresis, hyperreflexia,
~25% will progress to mutism, extensor posturing, fever, coma, death
• Wide variety in prognosis (improvement is possible)

Gutkha
• Areca nut acts as mild stimulant17
• Paan (“tobacco, seeds, quenched lime, spices, areca nut enfolded in
betal quid”) and Gutkha (“over three decades ago, a tobacco industry
emerged in India producing gutkha, which consists of slaked lime,
areca nut, chewing tobacco, spices, catechu packed in tins or
pouches”)17 are sold in South and Southeast Asia and in the diaspora
(10 – 20% of worlds population consumes areca nut)
ROUTES OF ADMINISTRATION - ORAL
• Erosive Esophagitis, Gastritis
• Direct toxic effect of ETOH + acetaldehyde
• Liver Injury
• Oral formulations of anabolic steroids have 17-alpha-alkylation
• Metabolized more slowly than IM formulations →↑ Hepatotoxicity

Bronchiolitis Obliterans
• Combustion of crack cocaine results carbon pigments which are inhaled and deposit in alveoli (due to their
small size) which in turn leads to accumulation of extracellular pigment (dark sputum on BAL) and the
accumulation of macrophages with large amounts of pigment15
• overload macrophages, intracellular, extracellular
• Barotrauma → pneumothorax, pneumomediastinum15
• Cough + Intentional Valsalva used in some crack cocaine users to
• Bronchospasm
• Smoked cocaine causes bronchospasm and wheezing in 32% of users15
• Bronchiolitis Obliterans in crack cocaine users
• Characterized by fibroblastic plugs in terminal bronchioles and alveoli15
• Cocaine causes Interstitial fibrosis in bronchiole epithelium and thick bronchiolar smooth muscle
hypertrophy15
• hypersensitivity pneumonitis vs. fibrosis (aka crack lung) found in 38% of autopsies of patients who had
positive cocaine test15
• This can progress to respiratory failure (thickening of alveolar septum)
• BAL shows elevated eosinophils
• CXR shows perihilar interstitial ground glass opacities
• Syndrome includes fever, hypoxemia, hemoptysis, resp failure,
• Crack Cocaine
STIMULANTS – PULMONARY• Pulmonary Hypertension
• Cocaine
• Lung histopathology from 52 autopsies of patients who tested positive
for cocaine
• 58% had acute hemorrhage
• 40% had chronic hemorrhage
• 38% had pneumonitis vs. fibrosis
• 77% had intra-alveolar edema (some cite as high as 85%)
Both IV and smoked cocaine → pulm edema
1. Rupture of submucosal blood vessels or injury to alveolar capillary network15
2. Can range from asymptomatic (discovered incidentally on autopsy) to hemoptysis to life threatening
hemorrhage15
5. No significant differences based on mode of use
6. Most common cause od death was cocaine OD, followed by “natural causes,” and homicides
a. Natural deaths = MI, ruptured aortic aneurysms, hemorrhagic stroke, fulminant hepatitis, asthma

STIMULANTS - CARDIOVASCULAR• Acute HTN
• Arrythmia
• Myocardial Infarction
• Ionotropic, chronotropic
• Increased SVR
• Impaired perfusion
• Vasoconstriction
• Dissection of coronary arteries
1. Risk of MI increases 24 fold in first hour after cocaine use
1. That said, on 2 retrospective studies of cocaine using patients presenting w/ chest pain; 6% had MI (most had
extra-cardiac cause)
2. CAN HAPPEN IN ABSCENSE OF CAD – chronic Cocaine may increase CAD – smoking is a confounder
3. Coronary vasoconstriction
4. Pulmonary effects (decreased oxygen)
5. If cocaine user has chest pain
1. ECG – look for ST elevation/depression
1. Cath lab (worry about stent thrombosis from either continued cocaine use or difficulty adhering to antiplatelet
therapy)
2. Fibrinolytic use is difficult given risk of AD
2. Cardiac troponins
3. Unstable vitals
4. If low risk follow w/ ECG for 12 hrs and d/c
6. Medical mgmt.
1. IV benzos if hyperexcitable
2. NO, phentolamine, verapamil may reverse coronary vasospasm, but may also further increase HR (including verapamil)
3. Non-selective beta blockers (labetalol)
4. Antiplatelet/anticoag31

a. aortic dissection
a. Methamphetamine is second only to idiopathic HTN in USA32
b. Cocaine users are extremely high risk
a. In 1 single-center study from 2002, 37% of cases of
acute AD also had cocaine use
This makes sense as in addition to an increase in BP, there is vascular
smooth muscle apoptosis and cystic medial necrosis that leads to
weakness or the arterial wall (also what leads to coronary and carotid artery
dissections)

QUESTION!!!Which of the following is false regarding dental disease among people
who use methamphetamine?
A. Oral health behaviors (brushing) are the most important determinant
of dental health
B. Smoking methamphetamine is more damaging to the teeth than
snorting or injecting
C. People who use methamphetamine drink more sugary beverages
than the general population
D. Bruxism, xerostomia, and poor access to dental healthcare all
contribute to dental disease
STIMULANTS – METH AND DENTAL HEALTH• Study: rates of moderate and severe periodontitis were 54.8% and 22.9%
• Compared 5% of age matched group from the 1999 – 2004 NHANES
• More frequent meth use did not increase risk for severe periodontitis
• No difference seen in route of administration (Smoking vs. snorting vs. IV)
These studies 80% men, 42% AA, 31% Hispanic, mean age was 44, 25% HIV positive,
70% were smokers, 34% took xerogenic medications; 64% used MA > 15 days per
month; 53% smoked exclusively36
STIMULANTS – METH AND DENTAL HEALTH• Likely contributing factors
• Age
• Likely more than years of use
STIMULANTS – METH AND DENTAL HEALTH• Likely contributing factors
• Age
• Bruxism
• Xerostomia
• Saliva inhibits strep mutans colony and biofilm formation
• Saliva acts as a pH buffer
a. Severity of xerostomia did not correlate w/ having more carries, but did correlate with severities of carries36
b. Neither mode nor frequency of meth use influenced severity of xerostomia36
STIMULANTS – METH AND DENTAL HEALTH• Likely contributing factors
• Age
• Bruxism
• Xerostomia
• Sugary beverage intake

• Uterine atrophy
• Stigma plays a significant role in exacerbating health issues faced by PWUD
• Route of administration can be a key determinant of what health effects PWUD experience
• For stimulants, most health effects are due to catecholamine surge, endovascular effects, an prothrombosis
• Alcohol and its metabolites are directly toxic and lead to large increases in oxidative stress. Alcohol decreases the absorption of micronutrients while increasing the absorption of bacterial particles
• Chronic inhalant use can damage the nervous system either due to its lipophilic nature or by direct inactivation of micronutrients
