Why Talk About It
• 1st question I was asked• General prevalence• Complicated issue: weed is not good or bad• Recent legalization:
possible upsides
![Page 6: A Harm Reduction Approach to Substance Use in Early Psychosis · 2020. 2. 25. · Harm Reduction: Definition •Harm Reduction International: •Refers to policies, programs, and](https://reader034.vdocuments.mx/reader034/viewer/2022051918/600ae1709b80676b1a66b1a1/html5/thumbnails/6.jpg)
Possible Upsides• Decreased stigma• Decreased risk of legal
issues/arrests• Increased willingness to
accurately disclose use• Fewer interactions with
drug dealers• Increased transparency –
what are people buying

Harm Reduction: Definition
• Harm Reduction International:
• Refers to policies, programs, and practices that aim primarily to reduce adverse health, social and economic consequences of the use of legal and illegal psychoactive drugs without necessarily reducing drug consumption. Harm Reduction benefits people who use drugs, their families and the community.

Harm Reduction: Principles
• Meet people where they are at• Risk is everywhere; does not ignore risk• Focus on reducing risk, not drug use• Sees drug use as a continuum
![Page 11: A Harm Reduction Approach to Substance Use in Early Psychosis · 2020. 2. 25. · Harm Reduction: Definition •Harm Reduction International: •Refers to policies, programs, and](https://reader034.vdocuments.mx/reader034/viewer/2022051918/600ae1709b80676b1a66b1a1/html5/thumbnails/11.jpg)
Harm Reduction: Principles• Important to recognize
positive changes individuals make
• Values the voice of users and former users
• Recognizes that drug policies themselves can increase risks to drug users
![Page 12: A Harm Reduction Approach to Substance Use in Early Psychosis · 2020. 2. 25. · Harm Reduction: Definition •Harm Reduction International: •Refers to policies, programs, and](https://reader034.vdocuments.mx/reader034/viewer/2022051918/600ae1709b80676b1a66b1a1/html5/thumbnails/12.jpg)
Developmental Context
• Fits with what we know about young people
• Experimentation and risk taking is the norm
• Rejection of authority
• Desire for autonomy
![Page 13: A Harm Reduction Approach to Substance Use in Early Psychosis · 2020. 2. 25. · Harm Reduction: Definition •Harm Reduction International: •Refers to policies, programs, and](https://reader034.vdocuments.mx/reader034/viewer/2022051918/600ae1709b80676b1a66b1a1/html5/thumbnails/13.jpg)
Developmental Context
• Endorsed by High Times and Leafly!

![Page 14: A Harm Reduction Approach to Substance Use in Early Psychosis · 2020. 2. 25. · Harm Reduction: Definition •Harm Reduction International: •Refers to policies, programs, and](https://reader034.vdocuments.mx/reader034/viewer/2022051918/600ae1709b80676b1a66b1a1/html5/thumbnails/14.jpg)
Assessing Use• Complicated issue
• Patient’s expect mental health professionals to view marijuana in a negative light
• Start out by asking about interests
• “Do you smoke much weed?”
• It’s not just a yes or no question
• Is drinking a glass of wine nightly the same as drinking a fifth of vodka everyday?
