Module One: Module One The Pharmacology of Crystal Methamphetamine
Crystal Methamphetamine: Crystal Methamphetamine Street names: Crystal; tina; speed; crank; ice; meth
Classification: Major central nervous system (CNS) stimulant (An amphetamine analog)
Other stimulants: cocaine; caffeine; nicotine; methylphenidate; dextroamphetamine)
Schedule II drug: High potential for abuse
Neurologically:
Triggers the release of large amounts of dopamine, a neurotransmitter, which causes an “energizing” euphoria; releases lesser amounts of seratonin
Inhibits the reuptake of synaptic dopamine
The Role of Dopamine: The Role of Dopamine Dopamine affects a region of the brain that controls pleasure
Dopamine is involved in reward behavior, leading to continued use of the substance that is subjectively experienced as pleasurable
While all stimulants release some dopamine, crystal meth releases much larger amounts:
Cocaine releases 400% more dopamine
Crystal meth releases almost 1500% more dopamine
Military metaphor has been used: If cocaine can be thought of as a conventional weapon, crystal meth is like a nuclear weapon

Forms of Meth: Forms of Meth “Crank” or “speed” consists of tiny granules that have the appearance of powder, usually more of a yellow appearance
“Crystal meth” or “Ice” is a form of methamphetamine that consists of large crystals that have the appearance of rock candy
Crystal Meth Modes of Administration: Crystal Meth Modes of Administration Harms associated with each:
Slamming (Injection):
IV
Skin popping
Muscle popping
Snorting
Swallowing (crystal-laced drinks; homemade pills: wrapped in tissue paper and ‘popped’ with water)
Smoking
‘Booty bumping’ (rectal administration)
Onset of Effects: Onset of Effects Smoked – 3 minutes
Injected – 5 to 10 minutes
Swallowed – 15 to 20 minutes
Drug, Set and Setting: Drug, Set and Setting The dose or amount of a drug taken
The mind set (expectancy), or what one expects to “feel”
The context and the environment in which drugs are taken
All of the above are primary factors in the overall effect
Why Do People Use Crystal Meth?: Why Do People Use Crystal Meth? Perceived desirable effects (Subjective benefits):
Provides energy; increases alertness
Lessens desire and ability to sleep
Increases sexual arousal
Increases stamina and enhances endurance
Reduces appetite
Induces sense of self-confidence; productivity
Focuses thinking; increases concentration
Distorts perceptions of time
Form of escape (from ‘hassles of daily living’)
Desired Effects Cited Among Studies of Gay Men: Desired Effects Cited Among Studies of Gay Men Enhances and/or prolongs intensity and frequency of sexual encounters
Keeps you active for weekend-long parties
Helps you escape from unpleasant emotions
In several studies this was linked to avoidance of dealing with one’s HIV status
Crystal use cited as a method of coping with “specter of death”
Physiological Effects: Physiological Effects Increases heart rate (tachycardia) and blood pressure
Increases shallow breathing (tachypnea)
Raises internal body temperature (hyperthermia)
Causes sweating, often profusely
Decreases appetite
Enlarges pupils
Causes dry mouth and bad breath (halitosis)
Causes pounding headaches
Increases motor activity (can’t keep still)
“Tweaking”: “Tweaking” Tweaking (crystal intoxication) lasts 8-12 hours, depending on dose and purity; may last several days from repeated dosing
Major symptoms may include:
Teeth grinding
Dilated pupils and staring/trance state
Bad breath
Severe paranoia and hallucinations
Rapid body movement; jerking
‘Meth bugs’ (parethesias, caused by an imbalance in sensory neurons) and may lead to picking one’s skin
Increased motor activity/performing repetitive acts
Crystal Meth Side Effects: Crystal Meth Side Effects Males: Sexual dysfunction:
“Crystal dick”: Erectile dysfunction in men
Men: Impotence; inability to achieve orgasm
Women: anorgasmic (inability to achieve orgasm)
“Crashing”: “Crashing” Withdrawal effect:
Extreme exhaustion
Sleep disorder
Suicidal ideation
Increased generalized anxiety and/or other anxiety disorders (agoraphobia)
Can lead to continued use (“crash avoidance”)
Using ‘downs’(sleeping pills) and/or opiates to alleviate withdrawal
Consequences: Consequences Additional problems with crystal meth:
Impaired cognitive functioning and short-term memory loss, notably abstract thinking and judgment
A person’s ability to perceive risks and consequences while tweaking is diminished (person may engage in high risk sexual behavior, linked to HIV infection and syphilis)
Mixing drugs when crashing: pain killers; sleeping pills (may cause Substance Induced Amnesia if the person doesn’t fall asleep)
Consequences of Long-term Use: Consequences of Long-term Use Addiction
Sexual compulsivity
Anorexia; distorted body image, or phobia about weight gain
Lethality results from kidney failure, dehydration, seizures (can occur after single use); cardiovascular events such as heart attack or stroke
“Meth mouth”: Lack of saliva production causes bacteria to grow, causing tooth decay
“Crystal-induced osteoporosis”: structural deterioration of bone tissue, which leads to bone fragility and loss of teeth

Physical Health Concerns: Physical Health Concerns Crystal use correlated with:
Increased rates of HIV, particularly among MSM
Increased rates of syphilis among MSM
Injectors at increased risk of Hep C
Increased risk of malnutrition
Lack of adherence to medications (HIV; psychotropics)
Continuum of Use: Continuum of Use Experimental use
Social and ritual use (parties)
Intermittent use (situational: social/peer networks; setting)
Binge use (operationalized as conscious, planned ‘heavy’ use for 5 or more days; potentially distinct from a “slip” for someone in recovery)
Abuse (305.70 DSM-IV-TR criteria)
Dependence (304.40 DSM-IV-TR criteria)
Severely and Persistently Chemically Dependent (numerous attempts to abstain; chronic relapse)
Who is At-Risk for Addiction?: Who is At-Risk for Addiction? The etiology of addiction is considered to be multifactorial (biopsychosocial)
Variables correlated with increased risk of addiction:
Psychological vulnerability (prior history of problems with other drugs or prior treatment)
Family history of addiction
History of trauma
Psychological Concerns: Psychological Concerns Low self-esteem; low self-efficacy, especially following relapse
Lack of intimacy; inability to sustain intimate relationships
Mood disorders (notably major depression)
Anxiety
Sleep Disorders
Cognitive impairment
Amphetamine-induced psychosis
Physical Health Concerns: Physical Health Concerns Malnourishment; anorexia
Physical exhaustion
Stress and impact on immune system functioning
Dermatological problems
Oral hygiene/dental problems
STI’s; HIV status
Acute and Post Acute Withdrawal Syndrome (PAWS): Acute and Post Acute Withdrawal Syndrome (PAWS) Acute withdrawal occurs about 3 days following last use (Detection in urine: as soon as 1 hour after initial dose; up to three days – depends on body mass -- for the drug to be eliminated from the body and no longer detectable in a urine test)
Post acute withdrawal may last months
Symptoms of PAWS are treatable:
Major Depression or other mood disorders such as Dysthymia
Sleep disorder
Psychotic disorders (paranoia)
Crystal Meth Issues and Problems: Crystal Meth Issues and Problems Experimentation and then cessation (Crystal meth is not “instantly addictive”)
Addiction and recovery (managing a chronic condition)
HIV infection/possible lack of adherence to medications
Increased rates of STI’s, notably syphilis
Escalating drug use and associations with violence:
Aggressive behavior
Drug dealing and involvement with drug dealers
Intimate partner violence
Gun violence (perhaps correlated with paranoia and aggression)
Module Two: Module Two HIV Risk Factors Related to Crystal Methamphetamine
Sexual HIV Risk Behavior: Sexual HIV Risk Behavior Pharmacology: Induces sexual arousal (“makes one horny”)
May lead to sexual compulsivity and multiple sexual partners (increased HIV risk)
Impaired cognitive functioning: perceptions of HIV risk become diminished or impaired so even with prior HIV knowledge, consequences of engaging in high risk behavior while high are not considered
Sexual Compulsive Behavior: Sexual Compulsive Behavior (Also known as Sex Addiction)
Two Criteria
Pattern of compulsively seeking sex and/or obsession or preoccupation with seeking sex
Continuation of behavior despite adverse consequences (i.e.- causing significant disruption in one’s life)
Sexual HIV Risk Behavior: Sexual HIV Risk Behavior Sexual dysfunction may occur as a side effect of crystal intoxication:
“Crystal dick”: Condoms may fall off
Impotence, the difficulty or inability to achieve orgasm, may lead to an individual seeking multiple sexual partners until orgasm is achieved
Use of sexual performance enhancing pharmaceuticals: Viagra, lasts 4 hours; Cialis or Levitra which lasts up to 36 hours
Sexual HIV Risk Behavior: Sexual HIV Risk Behavior Changing sexual roles (insertive/receptive anal intercourse)
Because of “crystal dick,” men who previously were “tops” may engage in receptive anal intercourse. “Bottoms” are at statistically higher risk of being/becoming HIV infected
“Bottoms” who use sexual performance enhancing drugs may “top” (become insertive partners). If they are HIV positive and don’t consistently practice safer sex while high, they may be infecting others
Identity/behavior discordance (the construct “MSM”): MSM who identify as straight are often not getting the information about HIV and STI’s that are targeting gay men
Sexual HIV Risk Behavior: Barebacking: Sexual HIV Risk Behavior: Barebacking Operational definition: the intentional decision to have anal sex without a condom
Barebacking as a choice and decision rather than a mistake
Term came into being in the mid-90s
Range and Patterns of Barebacking Behavior: Range and Patterns of Barebacking Behavior Barebacking as an activity versus barebacking as an identity
Prevalence and extent of barebacking behavior
Who does it? (Recent findings)
Why?
Among some of the variables:
HIV ‘fatigue’
Promotes intimacy
Sense of masculinity
Drug use, notably crystal
Defining the Problem: Defining the Problem Problems in definition: Only applied to MSM’s
Problems in measurement: how extensive is the behavior? (Individual behaviors versus community norms)
Scope of the Problem: Scope of the Problem Unknown, however, 262,000 references in September 2005 on Google search engine indicates fascination with the phenomenon
(In December 2003 there were 52,000 web references)
Evidence about the behavior seems based on extrapolations of HIV seroconversions in populations (CDC statistics)
Problem: Not all seroconversions are due to the conscious decision to have unprotected sex
Causes and Effects of Barebacking: Causes and Effects of Barebacking
Concern with effects (epidemiological impact) drives the search for the cause
Hypothesis: multifactorial
HIV seroconversion rates and STD rates (notably syphilis)
HIV+ and HIV- men: differential rationale for barebacking and using crystal meth
The decision to bareback is usually a subjective perception that there are some benefits: participant exploration
Perceived Benefits : Perceived Benefits “Feels better”
Enhances performance
Greater intimacy
May strengthen committed relationships between same status couples (non HIV infected)
Acceptance by peer cohort
Consequences: Consequences Personal: Increased disease risk
Psychosocial: emotional reactions: depression; anxiety; social isolation or ostracism
Drug use: co-factor; drug use may increase
Financial:
Possible treatment for medical conditions; psychotherapy; drug treatment
Possible lost income due to absences from work
Injection Drug Use (IDU): HIV and Other Blood-Borne Pathogen Risk Behavior: Injection Drug Use (IDU): HIV and Other Blood-Borne Pathogen Risk Behavior Crystal Meth is an injectable drug
“Slamming” is street slang for injecting crystal meth
“Slamming” crystal can be done in three ways:
IV
Skin popping
Muscle popping
What Service Providers Need to Know About IDU: What Service Providers Need to Know About IDU Injection drug use is considered to be a high-risk behavior for:
HIV
Other blood-borne infections such as viral hepatitis
Drug overdose
Information that providers can relate to consumers:
There are safer injection practices
Consumers/clients can use sterile syringe each time they inject; available in needle exchange programs; ESAP
Tools of Injection: Tools of Injection Needle
Shaft (size)
Lumen (size of opening)
Syringe
Barrel
Plunger
Tourniquet (tie) for intravenous injection
Drug itself
Intravenous Injection: Intravenous Injection Riskiest in terms of overdose
There is a direct opening of internal system with environment (risk of infection)
Avoid Arteries: Avoid Arteries Pulsing
Increased blood loss
Blood is bright red
Force can push back plunger of syringe
If hit in extremity, elevate above heart
Pressure for at least 10-20 minutes
Inserting the Needle: Inserting the Needle Tie tourniquet
Insert at 15 to 35 degree angle
Bevel up
Pull back slowly-should see dark slow moving blood
Untie tourniquet
Inject drug
Withdraw needle slowly
Vein Selection- Intravenous Injection: Vein Selection- Intravenous Injection Arms-first upper, then lower
Hands-veins much smaller and more delicate; easier to bruise
Leg
Larger role in circulation
Valve damage; much more likely to develop clots and emboli
Vein Selection: Vein Selection Feet
Close to nerves, cartilage, tendons
Farther from the heart than other areas resulting in decrease circulation
Damage takes much longer to repair
Groin Area: Groin Area Second most risky place to inject
Veins lie very deep
Vein very close to the femoral artery
major artery: must locate a pulse first
Very close to nerves
Riskiest Vein Selection Site: Riskiest Vein Selection Site Jugular vein in the neck
Lies close to the carotid artery-major blood vessel to brain
Hitting the carotid could be fatal
Subcutaneous Injection: Subcutaneous Injection Injecting through skin and fat layers
Effects come on more slowly than IV
Risk is real for abscesses
Usual site is upper arms or legs
Intramuscular Injection: Intramuscular Injection Typical effects are slower than intravenous
“Rush” not experienced
Lumen of needle is larger
Greater risk of deeper infections
Must avoid nerves, arteries
Unsterile Technique: Unsterile Technique Wound botulism
Localized infections
Abscesses
Eye infections
Cellulitis confined to one area
Systemic, in the blood, through the body
Tetanus
Yeast infections
Septicemia
Meningitis

Osteomyelitis: Osteomyelitis Infection in the bones
Original site of infection often elsewhere in the body
Adults-vertebrae, pelvis
Can progress to a chronic condition
Endocarditis: Inflammation of the lining of the heart : Endocarditis: Inflammation of the lining of the heart Symptoms: slowly (subacute) or suddenly (acute)
Diagnosis
Blood cultures
Echocardiogram Usual causative organism is bacteria, also:
Fungi
Virus
Sometimes unidentified
Necrotizing Fasciitis: Necrotizing Fasciitis Gangrene
Flesh eating bacteria (Streptococcus)
Must be caught early
IV Antibiotics
Surgical intervention
Mortality rate: up to 50%
General Safety Tips for All Injection Methods: General Safety Tips for All Injection Methods Emphasize “best practices” when working with injection drug using clients
Message: Use a clean syringe every time
Greatest risk for HIV and Hep C: Sharing of drugs, works
Crystal meth damages one’s cardiovascular system if injected; “switching” mode of administration might be encouraged as a harm reduction strategy
HCV Transmission: HCV Transmission With Hepatitis C contamination occurs more readily
HCV can live outside the body for 3 weeks
Safest to use all new works each time
Don’t share water
No proof bleach kills the virus
Use different water sources for mixing and cleaning
Prepare and inject yourself, if possible
Clean up after yourself-no blood left around!
Mark own equipment
Module Three: Module Three Case Studies
Module Four: Module Four Crystal Meth Users and Those Who Are Involved With Them: Continuum of Interventions
Responses to Crystal Users in the Workplace : Responses to Crystal Users in the Workplace Options:
Ignore this issue; deal with it on a case by case basis
Have clearly written internal policies and procedures to avoid scapegoating or discrimination
Hiring practices: Address at job application
Ongoing employee monitoring – ineffectiveness of urine testing
Agency Responses to Crystal Users in the Workplace: Agency Responses to Crystal Users in the Workplace Interventions
Harm Reduction Framework: Keep the person employed
Peer intervention model: Planned Intervention
Supervisory model
EAP/ MAP/ UAP model and referrals to outside consultants
Planned Workplace Intervention: Peer Model: Planned Workplace Intervention: Peer Model Planned Intervention: organized, sometimes professionally facilitated; “raising the bottom”
Non-attacking, civil, but somewhat confrontive approach; participants (co-workers, sometimes including friends) are encouraged to use “I” statements (“I was very upset when you borrowed money that you said you needed for bills but I found out you bought crystal instead” or “I’m so tired of covering for you at work.”)
Goals: To keep the person employed and to get a user to stop (usually by going into drug treatment; sometimes a member of a 12-step fellowship is there also to get the person to go to a meeting for the first time)
Workplace Concerns: Workplace Concerns For those in “safety-sensitive” positions (driving a van with clients as passengers)
For those professionals providing direct services to clients: Ethical Codes
Recommendations: Do not ignore the impact on client/resident care. Ultimately, consult with Human Resources if you are unsure of what to do
“Tough Love” Model (Zero Tolerance): “Tough Love” Model (Zero Tolerance) Aggressive confrontational approach
“If you don’t quit using, you’re fired.”
“If you show up for work again and your tweaking I’m calling the cops and I’ll have you arrested for trespassing.”
Gay press: Advocating having users arrested to reduce crystal use in the community
Advising people not to date users
Goal: To get the individuals to completely stop using (abstinence).
Problems with the approach: Poor long-term outcomes associated with “hitting bottom;” lack of support is a negatively correlated
Nagging: Nagging Focus on the drug user and the user’s behavior, often at the user’s request (“I need to be monitored.”)
“What were you doing in the bathroom? Where have you been for the last half hour? Who were you with?”).
Goal is to get the person to stop using or to stay stopped (prevent relapse).
Constant hypervigilant monitoring of the user
Problems with the approach: According to the literature, not very helpful; users become skilled at manipulation and become more deceitful; friends/lovers get stressed out and exhausted
Detachment Model: Detachment Model Focusing on the caretaker/co-worker/friend, not the user
Promoting self-care
Address codependency: Stop enabling and engaging in caretaking behaviors (making excuses for the user; covering for them at work; bailing them out of social problems)
Theory: You can’t necessarily change someone else’s behavior. By changing one’s own behavior, it may cause a change in the user’s behavior
Goal: Abstinence or cutting down so there is no “chaos” related to drug use
Applied in self-help programs (Al-Anon; Nar-Anon; Gam-Anon)
Explicit Harm Reduction Strategies: Explicit Harm Reduction Strategies Importance of Planning: When users explicitly say, “I’m not quitting, I just want to cut down or not binge anymore,” strategies may include assisting the person in:
Using less (focusing on consumption: quantity or money spent)
Using less frequently (using only on weekends; once a month)
Psychosocial stabilization: help stabilize the other areas of a person’s life so he/she regains a sense of control over his/her drug use (building self-efficacy)
Crisis Intervention: For Service Providers: Crisis Intervention: For Service Providers Crisis versus emergency
Usually self-limiting
Duration: 4 to 6 weeks, average is 4
A transitional period:
Danger of increased psychological vulnerability
Opportunity for personal growth
Immediate goal: Crisis resolution and restoration of pre-crisis level of functioning
Long-term goal: improve functioning
Approaches to Intervention: Approaches to Intervention Less focus on the developmental past of the individual
Information is solicited to gain a better grasp of the present crisis only
Emphasis is placed on immediate causes for disturbed equilibrium and processes to regain functioning
Steps in Crisis Intervention: Steps in Crisis Intervention Assessment: use accurate focusing techniques;
If someone is tweaking and paranoid, assess weapon possession ; rule out suicide; identify strengths and coping strategies (“It’s great that you came in for help”); ask user to identify social networks
Planning therapeutic intervention: Precipitating event usually 1-2 weeks prior to help-seeking; past 24 hours is frequent (a crystal binge or relapse)
Steps in Crisis Intervention: Steps in Crisis Intervention Intervention:
Help gain intellectual understanding of the crisis
Help identify and gain awareness of feelings (help contain feelings, not emote them)
Explore past and present coping strategies
Reopen social world
Resolution of the crisis and anticipatory planning
Reinforce positive change
Crystal Meth-Involved Couples Interventions: Crystal Meth-Involved Couples Interventions Assessment of strengths and deficits
Complex systems emerge: individual and mutual dynamics
“Give and take” versus rigid styles of relating
When drug use is involved, power and control issues are manifest
Often both people are involved with drug use, one being more ‘chaotic’
Presenting Problems and Issues: Presenting Problems and Issues Problem areas of couples’ functioning:
Conflicting values/beliefs
Communication
Role: Who does what?
Behaviors
Differential stress and coping skills
Time management
Interventions: Interventions Values clarification
Target Communication: Improve poor communication style; make the covert overt; communication training
