For 50% of these adolescents, the course of their illness is further complicated by a co-occurring substance use disorder, which often develops from repeated self-medication of PTSD symptoms.
The reality is that once established, both disorders serve to maintain and exacerbate each other, leading to extensive social, educational, physical and psychological impairments that lead to a chronic course of illness.
Therefore, it is imperative to intervene early to prevent the severe and long-lasting burden associated with this common comorbidity.
This research-based webinar will present, in an hour format, an overview of the current evidence regarding integrated treatment options available for co-occurring PTSD and substance use, plus promising new early interventions for adolescents.

Key Topics of this webinar:
- The relationship between substance use and PTSD and the consequences of its combined effects.
- The shift away from traditional sequential models of treatment towards integrated models that treat both disorders simultaneously.
- How new integrated exposure-based psychotherapies work for people with this comorbidity.
- What is the role of early intervention and what difference can make in this context?
- How adolescents respond to integrated exposure-based therapy at the moment.
Key learning outcomes:
- Greater understanding of the research association between PTSD and substance abuse disorders.
- Deeper understanding of the current burden of PTSD and substance use disorders.
- Enhanced ability to recognise and identity with the lived experience of PTSD and substance use, its social, economic, emotional and wellbeing impacts and how these might present in a clinical setting.
- Greater confidence in applying novel, evidence-based psychotherapies in ‘real world settings’ for people with co-morbidities.
- Pre-planning and preparedness for the emergence of new research currently under way in the field.

Kirsten Lee
Lived Experience
Kirsten grew up with a father who had a substance use disorder, who sexually abused her as a young child, and was physically violent every day throughout her teens.
At the age of 15, Kirsten was over-prescribed Ritalin for ADHD, and started to abuse it heavily. By 18 (when her father left), she was snorting 10-20 tablets of Ritalin and drinking 1-2 bottles of hard liquor a day as a minimum.
At 20, she was introduced to yoga and 12 step recovery, including Alcoholics Anonymous and Narcotics Anonymous, and was able to get sober and stay clean with a community of support and people healing.
She went back to university, worked as a fashion designer for a decade, then moved to design academia, teaching & research. Since then, she has become a respected and contributing member of her profession, 12-step, yoga and Buddhist communities.
At around 16 years clean, her trauma began to surface, and her father died. By then, she started attending other 12 step fellowships such as Alanon, Adult Children of Alcoholics (and dysfunctional families), plus trauma therapy at Birchtree Trauma Center.
Four years later, she is finding that the wounded areas of her life are finally starting to heal. Kirsten is now passionate about helping others heal from addiction and trauma. She loves to share her experience and hope that healing IS possible.
