Founded in 1994, Dopamine is a community organization located in Hochelaga-Maisonneuve whose mission is to help, support and work alongside drug users, their families and friends, neighbourhood residents and those from surrounding areas. We focus on HIV/AIDS and hepatitis prevention, as well as the prevention of other blood-borne and sexually transmitted infections.

We employ intervention strategies in order to alleviate the negative impacts and the harm associated with the lifestyle that drug use entails, as well as the prejudices, myths and representations which exist on an individual, community and societal level.


  • People who smoke or inject drugs

  • People involved in the sex industry

  • People living with/at risk of contracting HIV/AIDS or hepatitis C

  • People experiencing homelessness or social disruption

Our approaches and actions are guided by three values


Humanism reminds us of the importance of focusing on the quality of life of our service users rather than on their drug use. Guided by this principle, we welcome with a warm greeting all individuals accessing our services, and provide them with judgement-free, respectful support that takes their current circumstances into account.


Proximity is defined in terms of accessibility as well as the genuine needs of the population we serve. Through this principle, we acknowledge the importance of paying full attention to the needs communicated to us. This principle is also highlighted in the role played by the organization with regards to its community and partners.


Solidarity is embodied in the intervention team members’ commitment to building support relationships with individuals using our services.

I take part in Dopallies because it is a useful service for learning that has helped me to successfully change my behaviours. My way of talking with peers helps me stay focused on how to act safely. Prevention is important to me. Thank you.


Dopamine allows me to meet people and break my isolation.

Thank you for allowing us to do the Green Squad for many more years – we really care about it.

It was my first time volunteering with the Green Squad Green Brigade – I liked it so much that I want to do it again and again.

For me, Dopallies is a collection of relevant topics that help people on the street or drug users to deal with various issues that affect them.


I like when people from the neighbourhood come to us to talk to us, it shatters taboos and people do not judge us.

The Green Squad helps me keep my mind off using.

It allows me to resocialize and decompress as I have a tendency to isolate myself.

It is a meeting point and exchange point that breaks my isolation. It’s warm, welcoming, helpful, and supporting me in my efforts. A privileged moment that I appreciate due to its discretion and effectiveness.

I feel useful in my neighbourhood and Sainte-Catherine Street keeps looking prettier and prettier thanks to us.

I like walking down Sainte-Catherine Street and seeing the completed tree squares. I’m so proud!

For me, these are workshops on topics that concern us and directly affect us, as well as individual experiences that enrich us.


A source of information that is sometimes very useful in my daily life, an occasion to foster links with certain people, sharing without being judged… and I find it very informative.
