Individuals indicating risky substance use are randomly assigned either to a three-month online intervention on the Workit Health platform or a waitlist/treatment as usual. Those randomized to treatment will report reduced consumption of alcohol and other drugs and higher quality of life at study conclusion.

Inclusion Criteria:

• Subjects of this research are adults who self-identify as wanting to change their relationship to alcohol or drugs, who report currently using alcohol or drugs, or having recently stopped, who have access to an internet-enabled device, who are not currently suffering from untreated acute medical or psychiatric conditions, who anticipate being able to access the intervention over a six-month period, and who are able to freely consent to participate by themselves.

Exclusion Criteria:

• Because the intervention is written for an adult audience, as well as the logistical challenges of having private access to an internet enabled device, this research is limited to participants over the age of 18.
