The evidence
Why peer connection
Recovery wisdom and recovery science agree on remarkably little, but they agree on this: people stay sober through other people. This page collects the research behind that conviction, because our whole organization is a bet on it.
The scale of the problem
In the most recent national survey, more than 48 million Americans aged 12 or older had a substance use disorder, and the large majority of them received no treatment that year (SAMHSA, 2024 National Survey on Drug Use and Health). Excessive alcohol use is tied to about 178,000 deaths in the United States every year (CDC, 2024), and more than 79,000 people died of drug overdoses in 2024 (CDC NCHS, final data). And for people who do reach treatment, the most dangerous stretch often starts the day it ends: back home, in the evenings and on weekends, between meetings, where recovery actually has to be lived.
What the research shows
- The best-studied recovery program works through connection. A Cochrane review led by researchers at Stanford and Harvard, spanning 35 studies and more than 10,000 participants, found Alcoholics Anonymous to be the most effective path to alcohol abstinence studied (Stanford Medicine, 2020). Stanford's Keith Humphreys, a co-author, put the mechanism plainly: "AA works because it's based on social interaction." Follow-up research attributes much of the effect to the change in a person's social network (Kelly et al., Addiction, 2012).
- A single sober relationship moves the needle. In the Network Support Project, adding one abstinent person to a participant's social network was associated with a 27% increase in the probability of staying sober through the following year (Litt et al., J Consult Clin Psychol, 2009).
- Scheduled supportive calls help, for as long as they continue. Telephone continuing care after treatment produced better abstinence outcomes than standard group care in a clinical trial (McKay et al., Arch Gen Psychiatry, 2005). A longer trial found the benefit held while the 18-month program ran and faded after the calls stopped (McKay et al., Addiction, 2011). Those trials used professional counselors, whose hours are costly and whose calls eventually end. A peer relationship has no program end date.
- The connection is also the part that slips. Roughly half of the people who join AA stop attending within three months (Chappel, 1993). People leave for many reasons, and in our community's experience the between-meeting connection, including the daily call, is often among the first things to go. It was our founder's reason.
The daily call, and why it fails
Inside many recovery communities there is a practice older than any app: call another alcoholic or addict every day. Sponsors assign it to sponsees precisely because it keeps the social connection alive between meetings. And nearly everyone who has been assigned it knows how heavy it gets. The nickname for the feeling is the 500-pound telephone. Phone reluctance is not a character flaw and not unique to recovery: in one industry survey, 81% of millennials reported feeling anxious before making a call (BankMyCell, 2018). Add the sting of calls that ring out unanswered, and a practice that protects recovery quietly stops happening.
Notice the shape of the problem. The evidence says peer connection sustains recovery. The practice exists. What breaks is the mechanical step in the middle: someone, in a vulnerable moment, has to make the call and someone has to answer it. That step is the entire product surface of Crosstalk, and you can read how we take it on at how it works.
What we claim, and what we don't
The mechanism is well established: peer connection, kept up regularly, supports staying sober. What is not yet established is whether Crosstalk delivers that mechanism as well as we believe it can. That is precisely what our first pilots with treatment programs and peer recovery organizations are designed to measure, and we will report what we find, whichever way it comes out.
