Harmful Use
• “A pattern of psychoactive substance use that causes damage to health”. (a psychoactive substance is a drug that affects the brain)
– Physical• Eg hepatitis from the self-administration of
injected psychoactive substances– Mental
• Eg depression secondary to heavy consumption of alcohol

Dependence
• “A cluster of behavioural, cognitive, and physiological phenomena that develop after repeated substance use “
• Features are:– Strong desire to take the drug– Difficulties in controlling its use – Persisting use despite harmful consequences – A higher priority given to drug use than to other
activities and obligations– Increased tolerance (physical & psychological)– Physical withdrawal state.

Cannabis & Cannabinoids• Cannabis is found in the common forms of Cannabis
sativa and Cannabis indica• The term ‘cannabinoid’ (cannabis-like) include ~60
chemicals found primarily in leaves and flowering tops of female cannabis plant.
• Two specific cannabinoid receptors in the body– CB1located in brain and peripheral tissues– CB2 located in the immune system
• Depressant and hallucinogenic effects results primarily from stimulation of mesolimbicdopaminergic neurons via CB1 receptors (the mesolimbicarea is located deep in the brain)

Commonly used terms
• Marijuana : grass, hash, pot, weed, dope etc• Methods of smoking
– Joint: cigarette of marijuana
– Cone: a cone of cannabis, smoked via a water pipe (bong); Stronger than a joint

Cannabis
In 2004• 5.2% 12-15 yrs used cannabis• 18.0% 16-17 yrs• 26.5% 18-19 yrs• ~ stable since 2001
2004 National Drug Strategy Household Survey

What do people like about cannabis?
• Cheap (~$1-3 per cone); $25 & $50 bags• Easy to grow • Non-stigmatised• For “Relaxation”• To enjoy the ‘escape’ of perceptual distortions• Aids sleep difficulties• To relieve positive symptoms of schizophrenia• Relief of suffering (nausea, anorexia and distress)
associated with serious illness (cancer and advanced HIV)

Adverse effects
• Anxiety, dysphoria, panic, paranoia– especially among naive users
• Cognitive (thinking) and psychomotor (moving/activity)
impairment while intoxicated leading to..– Accidental injury– Impaired task performance
• Psychotic symptoms more likely if– high doses of cannabis
– vulnerability (genetic)

Natural history of cannabis use (under prohibition)
• Initiation in mid teens• Most use intermittently
– Surveys indicate a relatively low daily use capture rate
• Usually discontinue in mid to late 20s– ? Due to impact of ‘marriage, mortgages & children’
• Persistent use relatively rare, but more likely if– early initiation
– heavier use

But ……
• In those adults that continue to misuse, weekly or more frequent use accounts for 96% of use– Not so with YP (young people); binging more common
• Most YP smoke ‘heads’; fewer use bongs• If initiation of use is earlier, then:
– more regular use by younger users is likely
– more problem users and long term users
• More use among vulnerable groups• persons with schizophrenia
• conduct disordered adolescents

Common misconceptions
• “You can’t get addicted to cannabis”• “It’s a gateway drug (leads to use of ‘harder’
drugs)”
• “Rising potency in recent years, leading to more harm”
• “Causes schizophrenia “• “Harmless, and safer than many licit drugs”

Addiction. Is it a Gateway Drug?
• Theory: sequence of drug involvement– alcohol & tobacco precede cannabis, which
precedes amphetamines & other drugs
• However, < 5% of those who’ve tried cannabis go on to use ‘harder’ drugs
• Progression to harder drugs more likely if:– earlier initiation & heavier use– ?genetic vulnerability

Why association with other drugs?
• Selective recruitment to use– At risk youth more likely to use
• YP with conduct disorder have increased risk cannabis use (as well as amphetamines and psychosis)
– “Toxic peer group”- friends that use drugs• regular users affiliate with peers who use • peer culture supportive of drug use & crime
• Drug markets– provide opportunities to use other illicit drugs
• Genetic vulnerability – drug dependence– psychosis?

Is High Potency a Problem?
• For naive users– higher risk of dysphoria (bad trip) & psychotic
symptoms • This may mean higher rates of discontinuation?
a “positive?”• But may mean higher rates of accidental injury?
a “negative”?• For regular users
– lower respiratory risks (!)(they smoke less drug to get their fix, so less lung damage)
– But higher risk of dependence? • especially among adolescents
– more cognitive impairment?

Cannabis and psychosis• Cannabis psychosis-two types
– Toxic psychosis i.e. as a direct of the cannabis intoxication– Functional psychosis i.e. persists once cannabis no longer present
• Mild dose-dependent paranoia common
• High prevalence of cannabis use at same period of ↑↑↑↑ risk for psychosis– Males = 18-25– Complicates causal attribution
• Cannabis use is a risk factor for schizophrenia-why?• Possibly precipitates disorder in the vulnerable
– Historically - Swedish conscript study & many others– Numerous studies now support
• Cannabis use exacerbates psychotic disorders– Reasonable prospective evidence
– Adolescent (early) onset increases risk further

GeneticsThere is some now proven genetic factors that make one susceptible to developing psychosis and cannabis may interact with these genetic factors
when present• Catechol-o-methyltransferase (COMT)
– Located on chromosome 22q11, a region implicated in genomic scans of schizophrenia
• Involved in the metabolism of dopamine– disturbances in dopamine function have been implicated in the pathogeneses
of schizophrenia• G to A missense mutation produces a valine to methionine substitution at codon 158
( Val158Met)– Co-dominant (Val/Val; Val/Met; Met/Met)– Met/Met have the lowest COMT activity; Val/Val carriers having the highest
activity and heterozygotes having intermediate activity of the gene– Met form of the gene produces less enzymatic COMT activity and subsequent
slower breakdown of dopamine• Met/Met is reported to increase the risk of psychosis in the cannabis-smoking
adolescent by 10 fold

Speed - Physiology 101
Increase activity on the central and autonomic nervous system – Increase wakefulness; masks fatigue– Reduce appetite; increases insomnia– Promote heightened sense of well-being and
euphoria (feeling good)– Increase heart rate, blood pressure,
respiratory rate– Constrict vessels and dilate pupils

Neurophysiology 101
• Acute but transient blockade of the dopamine transporter (DAT) system
• Acutely increased dopamine levels in the midbrain (VTA & n. accumbens)
•• ““ PLEASURE BURSTPLEASURE BURST ””– highjacks the reward pathway – Also increased noradrenaline and serotonin
• Increased dopamine ⇒⇒⇒⇒ Psychosis
• BUT subsequent depletion of dopamine, noradrenaline and seratonin
• Sudden changes cause perceptual disturbances, withdrawal states

Dependence
• Psychologically and physiologically addictive ++
• Those who inject are at significant risk of developing dependence
• May not be a ‘daily use’ pattern
• Binge pattern common: use 3 - 5 days then ‘crash’
• There is often a concurrent dependence of abuse of other sedative or stimulant drugs, especially alcohol and benzodiazepines (adults)
• High risk factor for developing psychotic episodes

Withdrawal Symptoms
• Extreme fatigue and depressive symptoms• Escalates to a broad range of symptoms
– Change in appetite

Withdrawal (cont)
• Clinical signs suggestive of withdrawal present ~2 - 4 days after last use
• Most cases resolve in a few days to 2 wks (~ 15% persist for more than a month)
• Observation/symptomatic relief: sedationwith valium or similar
• Antipsychotics should not routinely be used as first line management for withdrawal

• Never indulged– 63% yr.9 males say they have never indulged in
sniffing– 89% yr. 11 males say they have never indulged (rate
has dropped from earlier years because VSM students more likely to drop out of education system and VS Misusers then move onto other substance

Effects
• Rapidly absorbed into the lungs and transferred to the brain and other organs with high lipid (fat) content– Neurons have a high lipid content– Neurotoxicity results from alterations in
neuronal membranes (not changes in neurotransmitter function per se).

Immediate Effects• Inhalants are central nervous system
depressants with some hallucinogenic properties in higher doses
• Symptom onset occurs within seconds• Intoxication starts after about 5 mins of repeated
inhalation (experienced users can control)• Peak blood levels occur around 15 mins• Signs of intoxication
– slurred speech, – ataxia, – decreased pain sensitivity,– visual disturbances ?? hallucinations
• Some acute reactions are a result of lack of oxygen

Patterns of Drug Use in Youth Detention
• Study 1:Lennings & Pritchard (1999) found 90% of young people in detention had some degree of drug/alcohol abuse. – 33% of these believed they had a problem.
• Of those, 70% thought they should have treatment
– >50% young people in detention met criteria for a substance use disorder (Teplin et al., 2002)
