Introduction Most commonly used illicit drug in the US More than 94 million Americans (40%) age 12 and
older have tried marijuana at least once Marijuana is responsible for more criminal court
cases than any other drug of abuse in the US 4% of the US population meets criteria for
marijuana dependence 23% of substance abuse admissions are for
marijuana alone Probably the most controversial drug of abuse in
the US

Adolescents Use in early adolescence correlates with
higher rates of adult substance dependence ~ 60% of adolescents in drug treatment
programs have primary diagnosis of marijuana dependence
The percentage of middle-school students who reported using marijuana increased throughout the early 1990s
In the past few years, illicit drug use, including marijuana, by 8th-, 10th-, and 12th-graders has leveled off

Chemical Composition >400 chemicals are found in Cannabis
sativa ~60 cannabinoids Acids, alcohols, aldehydes, amino acids,
esters, enzymes, glycoproteins, hydrocarbons, ketones, lactones, nitrogenous compounds, phenols, pigments, proteins, sugars, steroids, terpenes, and vitamins
Tar and CO are additional components found in marijuana smoke
![Page 11: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/11.jpg)
Cannabinoids Most are without known psychoactive
properties 9tetrahydrocannabinol (THC)
Major psychoactive compound in marijuana 8THC also a major psychoactive
constituent Despite psychoactive and physiological
potency, cannabinoids have remarkably low lethal toxicity Lethal human doses are not known
![Page 12: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/12.jpg)
THC Concentration In the last decades, the percentage of
THC has drastically increased A 1 gram, unlaced marijuana cigarette
provided ~10mg THC in the early 1970’s
1% THC by volume ~150mg THC in the early 1990’s
6-14% THC by volume If laced with hashish oil one joint can
provide ~300mg of THC Users prefer high THC content
marijuana to less potent marijuana

Methods of Use
Smoking Most common mode of
use Rolled into cigarettes Pipes Water pipes (bongs) “Fry” technique slows
burning to release more THC
Often combined with tobacco to enhance the high

The Marijuana High Euphoria or “high” within minutes of
smoking or about ½ hour if taken orally Sense of well-being Feelings of relaxation Altered perception of time and space Laughter Talkativeness Intensified sensory experiences
High typically lasts hours depending on dose and other factors

The Adolescent Brain is Still Developing During adolescence, the brain is
undergoing dramatic transformations In some brain regions, over 50% of
neuronal connections are lost Some new connections are formed Net effect is pruning (a loss of neurons)

Adolescent Brains
Motivational brain circuitry for pleasurable events develops much faster than the brain mechanism that restrains urges and impulses:
More likely to try drugs!

“Oops Phenomenon” First use to “FEEL
GOOD” Some continue to
compulsively use because of the reinforcing effects (e.g., to “FEEL NORMAL”)
Changes occur in the “reward system” that promote continued use

Prefrontal Cortex Has long been associated with
impulse control Documented as early as 1848
Abnormalities are associated with greater risk of SUD
Dysfunction may result in Preferential motivational response to the
pro-dopamine effects of drugs An unchecked progression of the
neuroadaptive effects of drugs leading to compulsive drug seeking

Gateway Drug Is Marijuana a Gateway Drug?
60% of teens who use marijuana before age 15 will subsequently use cocaine
Teens who use marijuana are 85 times more likely to use cocaine than teens who abstain
![Page 29: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/29.jpg)

Relation between Marijuana & other Drug Use
• Early age of onset is a major predictor both of continued frequent marijuana use & of likelihood of using other drugs (Denenhardt, et al. 2001, Lynsky, et al. 2003)
• The increased potency of marijuana may make the brain less responsive to endogenous cannabinoids. This may be especially marked in the still developing adolescent brain
• Combination of earlier onset & stronger marijuana may increase anxiety & apathy in teens & make other drug use more attractive
• Twin studies found early marijuana users had increased rates of other drug use and problems later on; odds of other drug use ranged from 2.1-5.2 times higher
![Page 31: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/31.jpg)
Addiction Liability ~10% who ever use marijuana become
daily users Conditional dependence – risk of
dependence of those who ever use substance Marijuana 9% Ethanol 15% Cocaine 17% Heroin 23% Tobacco 32%
![Page 32: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/32.jpg)
Pattern of Progression Kandel’s four stages:
Stage 1 – Experimentation Stage 2 – Recreational use Stage 3 – Problematic
19% of adolescents Stage 4 – Addiction
Progression from like to want to need

Marijuana Withdrawal Upon abrupt discontinuation, marijuana users report
delayed withdrawal syndrome producing Anxiety Insomnia Anorexia Irritability Depressed mood Tremor Drug craving
Symptoms can begin as early as 10 hours after cessation and continue for days to months
![Page 34: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/34.jpg)
Marijuana Withdrawal cont. Until recently the pharmacokinetics
(lipid solubility and long half life) of THC have made scientific inquiry into marijuana withdrawal difficult
Like cocaine, alcohol and opiates, withdrawal from marijuana is associated with marked increase of neuropeptide called corticotrophin releasing factor (CRF) in the amygdala, producing stress response and concomitant anxiety
![Page 35: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/35.jpg)
Chronic Marijuana Use Impaired learning secondary to
marijuana’s effect on short term memory and information processing
Delayed emotional development Discrepancy between what users’
believe and what is actually going on (in terms of relationships, self-awareness and overall functioning)
Amotivational syndrome (?)
![Page 36: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/36.jpg)
Chronic Marijuana Use cont.
SPECT images (top-down surface view) depicting a normal brain vs. a brain affected by chronic marijuana use
Defects of this type have been associated with attention problems, disorganization, procrastination, and lack of motivation
![Page 37: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/37.jpg)
Chronic Marijuana Use cont.
SPECT images show the underside surface where defects appear in areas of decreased blood flow & brain activity
Defects of this type have been associated with attention problems, disorganization, procrastination, and lack of motivation
![Page 38: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/38.jpg)
Marijuana and Pregnancy Women who smoke while pregnant have
babies with low birth weights and some studies show neurologic deficits in babies
Difficult to determine effect of marijuana secondary to poly-pharmacy
Research has shown that babies born to women who used marijuana during their pregnancies display: altered responses to visual stimuli increased tremulousness high-pitched cry
![Page 39: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/39.jpg)
Marijuana and Pregnancy cont. During infancy and preschool years,
marijuana-exposed children have been observed to have more behavioral problems and to perform tasks of visual perception, language comprehension, sustained attention, and memory more poorly than non-exposed children do.
In school, these children are more likely to exhibit deficits in decision-making skills, memory, and the ability to remain attentive.
![Page 40: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/40.jpg)
Psychiatric Issues Naive users smoking high potency marijuana most
common to receive ER treatment (anxiety/panic, paranoia)
Marijuana can precipitate anxiety/panic and even psychotic disorder in vulnerable individuals
Associated with other affective/mood disorders Increases suicide risk
ADHD ? Marijuana associated with impairment in memory, attention and executive function in numerous studies
Estimated attributable risk of cannabis use was: 13% for psychotic symptoms 50% for any disorder requiring psychiatric treatment
![Page 41: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/41.jpg)
Moore, Zammit, et al., Lancet, July 28, 2007“Cannabis use and risk of psychotic or affective mental
health outcomes: A Systematic Review”Key Findings:- The most comprehensive meta-analysis to date of a
possible causal relation between cannabis use and psychotic illness later in life
- An increased risk of psychosis of about 40% in participants who had ever used cannabis compared to never users. Affective disorders less clear
- A clear dose-response effect with an increased risk of 50-200% in the most frequent users
- The risk increased as the amount of marijuana used & the length of time used increased
![Page 42: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/42.jpg)
Marijuana and Psychosis
Heavy marijuana use may lead to earlier onset of schizophrenia in some adolescents Phenomenon is dose-response related Homozygous for the Val/Val variant of the catechol-o-
methyltransferase gene which codes for dopamine at greatest risk
Effect not due to self medication as no relationship found between early psychotic symptoms and risk of cannabis use
IV 9THC provokes dose-dependant positive and negative symptoms in people with schizophrenia
![Page 43: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/43.jpg)
Marijuana and Psychosis cont. Cannabinoid receptors in the brain regulate
the release of GABA, glutamate, dopamine, noradrenaline, serotonin, and acetylcholine Use of cannabis may set off a “cascade of
changes in neurotransmitter functioning” Most likely pathway leading to psychosis is by
9THC effects on dopamine and serotonin Remember the “dopamine hypothesis” of
schizophrenia Marijuana use may account for ~10% of
cases of psychosis in the general population
![Page 44: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/44.jpg)
Adolescents cont. Adolescents, age 12 to 17, who use
marijuana weekly are: 9 times more likely than non-users
to experiment with illegal drugs or alcohol
6 times more likely to run away from home
5 times more likely to steal ~4 times more likely to engage in
violence 3 times more likely to have
thoughts about committing suicide

Medical Uses of Cannabinoids Multiple possible uses:
Antiemetic Appetite Stimulation Anticonvulsant Antispasticity Analgesic
Interface with the opioid system Enhance release of endogenous opioids Attenuate Substance P release
Anti-glaucoma Movement disorders and other neurologic
conditions

Medical Utility of Marijuana Some efficacy shown in many areas However no studies are available
comparing marijuana to best known available treatments
Also, smoking as a delivery mode is undesirable because of toxicity and variability in dosing

Cannabis Youth Treatment Experiment(J Consult & Clin Psychology, 2004)
• Largest study to date, 600 substance abusing adolescents at multiple treatment sites
• Five treatment protocols of differing types & intensity of treatment, lasting 6-24 weeks Treatments included: MET/CBT 5, MET/CBT12 plus family
support, adolescent community reinforcement, family therapy
• High severity patients needed greater treatment intensity- Percentage of no use in the past month by self report
increased from 4% at baseline to 34% at end of treatment• CSAT has produced a separate manual for each of the 5
protocols, available at ncadi.samsha.gov

Conclusions• Over the last 3 decades, MJ potency has increased, age
of onset has decreased, & more individuals are seeking treatment for abuse/dependence
• While the causal link for the “Gateway Hypothesis” has not been proven, the association between marijuana use & later use of other drugs has been well established
• Use during pregnancy associated with later impaired executive function, learning, & memory problems
• A marijuana withdrawal syndrome has now been reliably documented in both clinical & human laboratory studies
• After chronic heavy MJ use, cessation can be very difficult and relapse is common. May need pharmacologic intervention
![Page 53: Marijuana and the Impact on Addiction and Recovery](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56813868550346895da018c1/html5/thumbnails/53.jpg)
Conclusions(continued)
• There is increasing evidence of the involvement of chronic MJ use in mood & anxiety disorders, earlier onset of schizophrenia, & schizophrenic relapse
• No generally effective treatment yet for marijuana dependence. Not as addicting as cocaine or heroin but the large number of users produces many casualties
• Both the public & the medical field have taken MJ use too lightly, leading to increased use & more casualties
• Increased knowledge of the endocannabinoid system should improve both treatment & potential use of derivatives from the cannabis plant

How Much Are We Missing? NCASA found:
> 40% of pediatricians failed to diagnose illegal drug use, even with classic presentation
> 40% of chemically dependent pts report PCP failed to diagnose addiction
Only 1 in 5 PCPs feel adequately trained to diagnose addiction
Time constraints, pt dishonesty about use and poor reimbursement sited as greatest barriers to diagnoses
