HISTORY CONT’D
* Between 1984 and 1986

A

– DEA used law (re: public safety) to “temporarily”
place drug in Schedule I category
– Hearings attended by scientists, psychiatrists,
psychotherapists, lawyers argued risks and benefits –> useful in therapy (problem was all anecdotal evidence) No control used** –> does it advance psychology at all??
- to keep at schedule 1: finding that this drug causes holes in brain (prions), also found brain damage (neuronal death) in rats (but not with MDMA but with MDA–> the amphetamine aspect AS WELL AS being injected into rats at much higher amounts than an oral dose)

Q

ADME

A
  • Taken orally (tablet or capsule) or intravenously (75-100mg)
  • can take up to 3 doses (300mg)
  • Effects realized within 30 to 60 minutes
  • Effects last 3-6 hours
  • Half life of 8 hours (40 hours to MDMA to leave the body)
  • Metabolized by specific enzyme in liver that is deficient in small percentage of white and asian populations (effects can last much longer)
  • problems with purchasing at rave (tablets will have more substances in it) up to 70 diff substance can be foudn in MDMA tablet –> 2004 TB talks about purity of MDMA is not as much of a concern as it used to be
  • there are testing kits (Dance Safe)

Q

Basic Behavioral & Psychological Effects

A
  • Increased Wakefulness — > elevated levels of NE
  • Increased Endurance –> NE
  • Heightened Sense of Emotional Closeness to Others –> from increases oxytocin hormone and reduction of fear response (love drug–> ironic cuz it is an SNS stimulant so you cant get an erection or orgasm)
  • Heightened Self-Awareness –> discuss and explain their feelings (therapy)
  • Feelings of Peace and Tranquility –> empathogen and enactogen as classification

Q

Some Adverse Psychological Effects

A
  • Psychosis-Like States UNCOMMON –> hallucination (not common but can occur), paranoia and fear (someone is after you), disorganized thinking or speech (tangential),
  • advocates of E –> have a genetic vulnerability to the drug (emotions exprerienced could be triggerd by other response ) –> trigger for preexisiting condition within them
  • Pronounced Anxiety–> not paranoia but highly anxious
  • Depersonalization and Derealization NOT COMMON –> depersonil (feel like they are separated from rest of world (glass separating them), detached form environment
  • derealiz: enivormnent seems meaningless, people dont look real (cardboard)
  • adovcates: say they occur spontaneously in the everyday world
  • Depression (variable duration and intensity) –> come down
  • can range in intensity or severity (low mood) –> loss of pleasure
  • length of dep cna be variable (can be one day w/ low mood to showing clinical depression for 6 months)
  • longer lasting depression = damage to serotinergic terminals (take 6 months for damage to be resolved)
  • Cognitive Deficits? –> chronic use causes impaired attention, concentration and memory
  • studies show mild mem deficits in delayed mem , some studies who NO deficit
  • poly drug users can worse mems
  • poor control in controlling for fatigue and premorbid attention problems
  • Sleep Disturbances–> 3 days- months
    -longer lasting sleep problems is accompanied by excessive dreaming and scary nightmares

Q

Medical Risks Associated with MDMA Use
* Hyperthermia (increase in body temps)
– Factors contributing to hyperthermia (2)

A
  • Prolonged exertion, warm environment
  • Elevated levels of serotonin
  • common cause of death from hyperthermia: disseminated intravascular coagulopathy******* (DIC) –> get blood clots forming throughout the body and they burst (internal bleeding!!!!)

study by Kalant (2001) et al: of 87 deaths 30 were due to hyperthermia
- most common cause of death of MDMA
- but if you get quick medical attention you will not die
- repetitive movement in club from NE, you can disregard the warning signals
- 9 were due to swelling of brain (hyponatremia)
- 4 were due to liver damage

Q

Medical Risks Associated with MDMA Use
* Acute Hyponatremia

A

– Low plasma sodium level due to dilution of blood with water
– Occurs as a result of: (2)
* Excess water intake (repetitive behaviour from MDMA) –> overdo it
* MDMA caused secretion of anti-diuretic hormone (ADH) , which promotes water retention by kidneys

A
  • Hepatitis (NOT COMMON) 50 reported cases all time –> damage and inflammation of liver

– Severity ranges (mild to severe)

Q

Tolerance

A
  • Tolerance develops to most of the positive
    effects in a few days
  • Tolerance dissipates within a few days to a week
  • With chronic use, amphetamine like effects are effects primarily seen –> increased endurance, alertness
  • MDMA (mix of mescaline and amph) –> increased endurance, wakefulness

Q

Dependence

A
  • Dependence issue “cloudy”***
    – Animal studies suggest dependency potential
    – animals will engage in task to get extasy and then Will self-stimulate/administer (Ratzenboek et al 2001, Schenk et al, 2003, Fanlegussi, 2007)
    – However, greater self-stimulation seen with other drugs than extasy (coke or nic vs MDMA)

– Few cases of “severe withdrawal symptoms” in humans
–> hav been cases that are consistent with dependance –> meets criteria for dependance disorder

– One of the first published studies (Janzen, 1999) reported three cases met the criteria for dep
1. 19y/o night club owner –> convulsions later still foudn it difficult to stop (aka dependance)
2. 30 y/o male poly drug user (not best study from doing more drugs) –> gained access to a large amount of M powder (intravenously admin 4x per day)
3. 38 y/o male w/ PTSD –> symptoms was emotional detachment (made him feel more connected with people ) –>
- collectively they all showed tolerance (increase in # of tablets)
- spent more time in using
- had more recover time (ex: night club owner would crash in the week days and then would feel better on weekends)
- relationships broke down
- lost jobs
more social isolated
- mild physilogical withdrawal symps
- fatigue
- weakness
- anadonia (loss of pleasure in normal pleasure activities)

– Tolerance, increased time using and recovering, neglected other activities , unsuccessful attempts to case use, mild physiological “withdrawal” symptoms

17
Q

Dependence

A
  • Examples of studies showing users meeting
    criteria for lifetime Substance Dependence
    Disorder/Estascy Dependence Disorder

– Topp et al (1997) –> 64% of 185 “regular” ecstasy users were dependant
- symptoms showed
- compulsive use despite problems
- giving up important actiivtes
- couldnt withdraw

– Hansen and Luciana (2004) –> 53% of 26 US University students were dependant

– Parsons et al (2009)
– New York night club attendees–> 19% were dependant (more % met criteria for cocaine)
- 400 sample size

– Cottler et al (2008)
– 43% of 52 users were dependant

18
Q

Dependence

A
  • Question re: withdrawal symptoms reflective
    of a true abstinence syndrome vs “come-
    down” effects

– Neuroadaption OR recovery phase
* e.g., Up or down regulation of receptors, damage to serontergic terminals vs “crash”

19
Q

If there is withdrawal, what does it
look like?

A
  • autonomic hyperactivity (physical restlessness) , sweat, heart palps
  • psychomotor agitation or retardation; insomnia or hypersomnia; (falling or staying asleep, long periods of time)
  • fatigue; nausea, vomiting, or changes in
    appetite; (apatite very notable)
  • transient visual, tactile, or auditory
    hallucinations or illusions; (canmeet criteral for HPPD)
  • muscle aches;
  • Anxiety; irritability, low mood, vivid, unpleasant dreams
20
Q

If there is psychological
dependence what does it look like?

21
Q

Dependence
When I start selling my stuff, my own apartment stuff, then that’s when I knew I got it out of control. And to this point now, I’m like
okay, I make enough money to buy it . . . I have enough in the bank right now to just sit there and it’s like I am a user, but I don’t think I am that bad of a user.

  • She later said

Right now, I think it is still a little out of control, not as much out of control as me pawning and selling and prostituting myself for money, none of that. But, now that I sit back and actually think about it I am losing a little control. (Singer and Schensul, 2011)

= compulsive use of drug!!

A
22
Q

Dependence (excerpt from intreview)

A
  • E: Have you ever tried quitting Ecstasy since
    you’ve really been on it?
  • P: I’ll be saying I ain’t gonna take no more pills
    but I always end up taking back another pill
  • E: Okay. Do you think it’s addictive to you?
  • P: Yep
  • E: Why do you think it’s addictive?
  • P: Because I always be wanting to take an E pill
    (Singer and Schensul, 2011)

= compulsion

23
Q

Trajectory of Ecstasy Dependence

A
  • Von Sydow et al (2002)
    – 93% decline in use 3 years later
  • 50% no longer using drugs
  • 43% still using but not as much
  • not a long lasting dependin (93% decline in use 3 years after)
  • reevaluated (53% stopped)
  • 43 % still using but not as much
