A newly launched governmental program

The priority of the current five-year Drug Strategy (2004-2008) :
reduce cannabis use among young people.

A press campaign focused on the risks of cannabis use.

Specific services targetting young cannabis users and their
families.

An additional funding of 3 M€ (£2,100,000) distributed to existing
treatment units to provide counselling (2005).
 Aim of the program : develop & disseminate a brief intervention
technique for cannabis use disorder to be used by primary
healthcare providers.

An « original » adolescent clinic setting : an intervention framework
including check-up and follow-up throughout 5 sessions.




Facilitate access to treatment : care provision ranging from
counselling and assessment to advice and throughcare;
Ensure that provision is built around the needs of young people
(motivational therapy);
Build service and workforce capacity;
Strengthen accountability.
The development of an evidence base of
an effective program
 The need for an appropriate outcome-monitoring tool over the
first year of activity :
 What are the characteristics of the target population?
 How is targeted work with cannabis-dependent clients
provided across all areas ?
 What works?
 A monitoring work carried out to assess the effectiveness of this
new setting :
 A monthly indicator system : scrutinize the numbers of clients
& the proportions of cannabis users and relatives.
 A national survey which is to be repeated next year : describe
the clients, map professional practices and evaluate the
effectiveness of the program.
Methodology and response rate
 Designed to examine :
the profile of check-up-seeking cannabis users;
 the care provision delivered to them in this clinic setting;
 the practices developed by healthcare providers.
Participants and setting :
 4,200 study cases : cannabis users (70%) or relatives (30%).
 3,000 cannabis outpatients aged 10 to 56 years recruited
between March 2005 and April 2005 and followed until
June 2005.
Data collection methodology : in-person interviews carried
out by practitioners.
Data processing : cases were retained only if respondents
provided data on the frequency of cannabis use.
Response rate : 90% of cannabis users’ specific services.

Results (1): Client characteristics
 Sociodemographic assessments :



85% are 14- to 25-year-old clients / 15% are older
A large majority of male clients (80%)
Lower proportions of school-attending individuals than in
the general population at 18
***
 Frequency of cannabis use : 64% are daily or near-daily
cannabis users and 36% are occasional users
 Patterns of cannabis use :


The age of onset for regular cannabis use most frequently occurs
during early adolescence (before age 15).
Regular cannabis use is frequently intertwined with alcohol use.
***
 Referral : 40% are justice referees; 30% referred by a family
member, friend or relative; 30% are self-referred (frequent
abuse or dependence diagnosis)
Results (2) : Justice referees
 Compared to self-referred clients, highest proportions of male
individuals
 related to the predominance of men among arrested drug
offenders.
 Justice referees are more likely to be young adults (aged 19 to 25)
than minors (x2).
 More likely to be out of school or unemployed than self-referees
and family-referred clients (x2).
***
 Justice referees are more likely to report moderate cannabis use.
 Their follow-up is shorter than other clients’: most interventions
are interrupted after 1st contact (end of intervention or dropout).
Results (3) : Dropout rates
 About 30% of clients drop out of the program.
 Remarkably high rates after 2nd contact (55%):


Related to longer waiting times (7 days after 1st contact, 15 after 2nd)
Reaches its highest point among occasional users
 Higher for young adults (19- to 25-year-old cannabis users) than
for minors.
Determining factors :
 Significant impact of the therapist on program completion :
medical practitioners retain significantly more clients than educators.
 Difference in client retention among GPs and other medical
therapists (psychologists or nurses), particularly at 1st contact
 Waiting times and access : a 1-week-long waiting time between 1st
and 2nd visit increases the likelihood of a drop out (x 3)
Results (4): Professional practices
 Administration of screening tests :



A half (47%) of these care providing services only use
substance-abuse screening tests (CAGE, ALAC, CRAFFT, etc.)
40% use internal screening tests (< 10 cannabis users
monthly)
13% do not use any.
 Diagnostic criteria :


Daily use is the discriminating factor to be classified as
cannabis-dependent rather than in abuse.
Impact of the therapist : GPs tend to classify cannabis
use as being at least « at risk » rather than moderate
(x4)
Discussion
 These findings provide good supportive evidence for the
relevance of the program :


Target population of youths reached.
One third of self-referees.
 They help identify the gaps in policy delivery :
 Pointing out predictors of dropout : a key information to find better
ways of retaining people in the program
 Single-substance focus may be potentially misleading
 They also raise a number of issues :
 What outreach strategies have to be developed to attract female
clients?
 Are the scoring procedures sufficiently streamlined ? A specific need
for standard screening methods easy to incorporate in office routines.
Conclusion
 Diversified data undoubtedly useful to
improve policy delivery
 … unless / even though they are used to
back up a political message
 Do research interest and media planning
intentions inevitably go together ?
Limitations
 Work relying on self-reports of drug use
 Generalizability
 Completion and dropout rates : imprecise proxies for the
check-up process … only a prelude to research on what occurs
during the «black box» of health care.
