Young Adult Substance Use Program (YA-SUP)
Young adulthood is an "in-between" period of transitioning from adolescence to adulthood. That is why other names for people in this age group include Transition Aged Youth or Emerging Adults. It is a unique time for self-discovery, building relationships, and becoming independent. Many young adults also experience lots of uncertainty and change. This can make the transition challenging to navigate. The Young Adult Substance Use Program (YA-SUP) aims to meet these unique needs. We offer 2 separate streams. There is a Young Adult Stream for young adults (17-25) looking to make changes to their substance use. We also offer a Loved Ones stream, for loved ones of young adults with substance use problems.
Who is the program for?
Young adults aged 17-25 who are looking to make changes to their substance use.
