Online communities can provide social support to those in need and can foster personal empowerment for individuals experiencing distress. This study examines the content of a Reddit community dedicated to the support of people trying to quit using cannabis, in order to develop an understanding of the type of social networking occurring on this subreddit (e.g. community).


A total of 100 Reddit posts and their replies (i.e. comments) were collected from the subreddit on June 12, 2015. Posts were qualitatively coded for expression of DSM-5 symptoms of cannabis use disorder (CUD) as well as other prominently featured themes. Comments on posts where individuals were seeking support/advice were also coded.


91 people posted the 100 Reddit posts, and of those 35 (38%) people described enough symptoms to be classified as mild disorder severity, 15 (16%) moderate and 11 (12%) severe, as outlined in the diagnostic criteria for CUD. Over half of posts (n=51) were seeking advice and/or support from members of the community. There were 174 comments made by 108 unique people on the advice/support seeking posts. Most were supportive/encouraging in nature (140, 80%) and gave advice to the post author (126, 72%).


This exploratory research highlights the potential of online communities as tools for individuals coping with addiction recovery, and future research should investigate if involvement in such communities would be a beneficial supplement to more traditional recovery practices.


Reddit is a popular content-sharing social networking site ( with roughly 7% of U.S. adults using this platform. 1 Reddit has over 200 million unique visitors every month with around four million users logging in every day, 2,3 and the user base consists largely of young (18–29; 58%) males (69%). 1 Reddit is organized into many different subreddits (i.e. communities) where people can post and comment on others’ content.

In a recent commentary, Reddit was praised for multiple subreddits that “help people get sober and stay sober”. 4 Accordingly, in this study we examine one large subreddit (nearly 25,000 subscribers) that exists as a space for discussions surrounding cannabis cessation and sobriety from other like-minded individuals. In order to respect the anonymity of the group members, throughout this report the community will be referred to as QuitCannabis.

Online communities can provide social support and can foster personal empowerment for individuals experiencing distress. 5,6 Such mechanisms are important for helping individuals avoid and cope with relapse-inducing situations as indicated by the Relapse Prevention Model (RPM). 7 In this study, we examined the content of QuitCannabis posts to develop an understanding of the type of social networking occurring on this subreddit. Specifically, we looked for the mention of symptoms of cannabis use disorder (CUD) as outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to identify the CUD symptoms expressed by individuals using this subreddit for its intended reason, “to help people stop smoking [cannabis]”. In keeping with the RPM, we investigated if the responses (i.e. comments) to posts provide specific strategies for coping with the possibility of relaspe. 7 In doing this, we aim to inform the potential value of using online support groups, like QuitCannabis, to support the CUD recovery process.


This study was granted a non-human subjects determination by the University’s Human Research Protection Office. All Reddit posts in this study are publicly available. However, given the ethical concerns of social media research, 8 no usernames of the post authors are reported. Similar precautions have been observed in other social media studies. 9–11 Data collection

Reddit organizes user-generated content (i.e. posts) using various filter tabs. Posts appearing under the “hot” tab are determined by an algorithm that considers the time the entry was posted as well as the number of up and down votes the post receives. 12 This tab captures posts that are rapidly gaining popularity (i.e. recent and more upvotes) on the site. Depending on the user’s settings, the first page in a subreddit can display up to 100 posts. Therefore, we collected the first 100 “hot” posts and all accompanying comments from QuitCannabis on June 12, 2015 using NCapture, an online extension of NVivo 10 qualitative analytic software. NCapture takes a screenshot of web-based content and generates a PDF for coding in NVivo. The post author’s username, number of post comments, and comment author usernames were recorded

Theme development

Reddit Posts.

Two research team members examined half of the 100 post sample to inductively develop codes based on reoccurring themes within the data. Recurring themes of interest and/or fitting with the RPM are described below. Individuals tended to self-report symptoms consistent with CUD. The DSM-5 criteria for CUD are: 1) consuming cannabis in large amounts; 2) persistent desire or unsuccessful attempts to cut down/control use; 3) spends lots of time trying to obtain or use cannabis; 4) experiencing cravings or strong desire to use; 5) trouble fulfilling major obligations (work, school, home); 6) use causes/makes worse social or interpersonal problems; 7) gives up or reduces important activities; 8) uses in situations that are physically hazardous; 9) has a physical and/or psychological problem from cannabis use; 10) increased tolerance; 11) experiencing symptoms of withdrawal. 13

All 100 posts were coded for the expression of these symptoms. For each unique post author (91 Reddit users posted the 100 posts), the DSM-5 criteria were tabulated based on their posts and each user was assigned a DSM-5 disorder severity level of mild (2–3 criteria), moderate (4–5 criteria) or severe (>6 criteria). 13 Most posts did not specify how long they had been experiencing a symptom; therefore some CUD symptomology language was altered in the codebook to remove the “time” criteria.

We coded when QuitCannabis was mentioned as a good/motivating/encouraging resource or when considered a useful relapse prevention tool. Environmental/social barriers to quitting were coded, which the RPM signifies as high-risk situations for relapse. Posts that discussed tactics for quitting, including cognitive reframing to deal with triggers and changes to lifestyle (i.e. exercise more, meditate) were coded, which are consistent with the RPM’s framework to prevent relapse. 7 . Additionally, we coded when individuals sought advice/support on QuitCannabis, experienced/looked forward to positive results from quitting, and/or mentioned using cannabis to self-medicate from a physical or psychological problem. Multiple themes could appear in a single post.

Clinical characteristics were also recorded including duration of sobriety from cannabis, duration of use, frequency of use, and age of first use.

Post comments.

The number of comments was recorded for each post at the time of data collection. In posts where individuals were seeking advice and/or support, the comments replying directly to the original post were also coded to ascertain the nature of the responses. From the comments, we captured the comment author’s username (i.e. commenter) and any indication if/how long the commenter was sober from cannabis use. The sentiment of the post was identified as being supportive/encouraging/positive, negative, or neutral/unable to discern. Separately, it was recorded if the commenter provided advice to the post author. Types of advice were coded based on intervention strategies outlined in the RPM: 1) Cognitive reframing procedures (i.e. advice that recommended alternate cognitions for mentally processing/coping with recovery process) and/or 2) Lifestyle intervention strategies (i.e. advice that recommended engaging in a specific activity as a coping mechanism). It was also noted if the advice was given in response to coping with a high-risk situation, 7 and if there was a specific suggestion to counseling or a 12 step program. Comments that gave advice that could be detrimental to maintaining sobriety were also coded.



Each of the 100 posts was coded by three team members. Posts were divided into five sets of 20. Each set was first coded separately by each of the three coders, and then discrepancies were discussed until a consensus was reached. Discussing discrepancies within the group allowed coders an opportunity to reflect on how their own personal impressions of the data impacted their code selection. The agreed upon codes then reflect a more objective interpretation of the material. 14 These agreed upon codes were then entered into NVivo for tabulation of themes.


Responses/comments to posts where individuals were seeking advice and/or support were classified by two members of the research team for presence of the themes outlined above. Comments were first coded separately by each coder and any discrepancies were addressed before coming to a final agreement.

Statistical analysis.

The indicators of CUD and advice giving were compared by cannabis use status (used within the past 30 days versus did not use within the past 30 days) of the post author or commenter using Pearson chi-square tests or Fisher’s exact tests as appropriate. SAS version 9.4 for Windows (SAS Institute, Inc., Cary, NC) was used for these analyses.


Characteristics of the Reddit posters in QuitCannabis

The 100 posts were posted by 91 unique usernames (i.e. post authors), with a median number of four comments per post (range 0–33). Post authors commonly mentioned duration of sobriety (51/91, 56%). The majority (36/51, 71%) indicated being sober for less than one month, and of those, most were sober for less than one week (29/36, 81%). Only six people had been sober for over one year (6/51, 12%).

Of those that mentioned duration of use (38/91, 42%), 39% specified using between 1–5 years (15/38), and 29% between 6–10 years (11/38). Eight posts expressed cannabis use for longer than 10 years (21%), and four for less than one year (11%). Only 17 posts revealed age of cannabis initiation (M=16 years, SD=2.5 years).

DSM-5 cannabis use disorder criteria

Of the 91 unique post authors, 35 (38%) people described enough symptoms to be classified as mild disorder severity, 15 (16%) moderate and 11 (12%) severe, as outlined in the diagnostic criteria for CUD. 13 The remaining 30 (33%) people expressed less than two symptoms, and therefore were not classified into a severity category. It is possible that these individuals could meet the criteria for CUD, however because they did not express those symptoms in the post, their CUD status remains unknown. A greater proportion of post authors who were current users (i.e. sober less than 30 days) displayed enough symptoms to reach at least mild CUD (28/37, 76%) than non-users (6/17, 35%) (χ 2 df=1=8.1, p=0.004).

Of the DSM-5 criteria mentioned, having a physical and/or psychological problem from cannabis use was expressed most often (42/91 people, 46%), followed by expressions of persistent desires or unsuccessful attempts to cut down/control cannabis use (40/91 people, 44%). Other common symptoms described included withdrawal symptoms (33/91 people, 36%), cravings (29/91 people, 32%), cannabis consumed in large amounts (24/91 people, 26%), social or interpersonal problems caused or worsened by cannabis use (21/91 people, 23%), giving up or reducing social/occupational/recreational activities (18/91 people, 20%), and spending lots of time trying to get or use cannabis (18/91 people, 20%) ( Table 1 ).

Comments on advice/support seeking posts

A more in depth analysis was conducted on the 51 posts where the user was seeking advice or support. There were 177 comments directly replying to these 51 posts. Three comments were authored by the same person who wrote the original post and were removed from further analysis, leaving 174 comments made by 108 unique people. Half of these individuals did not disclose their length of sobriety from cannabis within the comments (54/108, 50%), however 31% (n=34/108) indicated they had been sober for less than 30 days (i.e. current users) and only 13% (n=14/108) had been sober for more than 30 days (i.e. non-users). Six people mentioned they were in recovery (i.e. a successful quitter, no longer uses cannabis), but did not mention a specific time frame.

The overwhelming majority of the 174 comments were supportive/encouraging in nature (140, 80%). There was only one negative comment, and the remaining were neutral or sentiment could not be discerned (33/174, 19%). Roughly 72% (n=126) of comments gave advice to the post author. Of those, 42% (n=53/126) suggested some form of lifestyle intervention, 17% (n=21/126) presented a strategy for cognitive reframing, and 20% (n=25/126) suggested both a lifestyle intervention and a strategy for cognitive reframing (see Figure 1 for examples). Advice on how to cope with a high-risk situation was observed in 24 (19%) comments, and 9% (n=11/126) specifically suggested counseling or a 12 step program. The advice presented in the remaining comments was not specific enough to be classified. Advice that could be potentially damaging or threaten an individual’s recovery was only observed in 3 (2%) comments. Further comparisons revealed that among commenters, a greater proportion of those who were non-users provided advice (19/20, 95%) compared to those who were current users (23/34, 68%) (Fisher’s exact test p=0.022).

QuitCannabis advice-seeking posts with accompanying comments demonstrating types of advice provided


We found that the QuitCannabis subreddit is an accessible online platform for users seeking support and encouragement from other like-minded individuals. Most responses to posts in QuitCannabis were supportive and provided advice. The individuals on QuitCannabis who provided details on their length of sobriety were often in the early stages of quitting (i.e. sober less than 30 days), which contrasts with some in-person support groups like Alcoholics Anonymous where a successful non-user/quitter (i.e. sponsor) provides support and guidance to a recent quitter. There could be a cause for concern if the interactions on this site were not supportive or were providing coping strategies that could be detrimental to a successful recovery. However in our analysis of the advice provided on QuitCannabis, only three of the 126 comments provided concerning advice (i.e. “give [the cannabis pipe] to a stoner friend who will give it back no big deal if you want it again”), while the remaining comments were sound advice on how to mentally and physically cope with the struggles associated with quitting cannabis use. The lack of advice referring QuitCannabis users to seek out treatment is noteworthy, but not surprising when considering that cannabis users often quit without treatment and tend to express that treatment is not necessary to quit. 15,16 Considering individuals early in the recovery process are particularly vulnerable to relapse, 17 QuitCannabis appears to offer individuals quitting cannabis use with a space for self-expression, social support, anonymity, and can foster a sense of community, 18–20 which are important factors to potentially decreasing relapse risk. 21 Our findings also highlighted QuitCannabis users’ perceived environmental/social barriers to quitting. As these barriers potentially signal high-risk situations for relapse, 7 clinicians in training could use QuitCannabis as a tool for better understanding barriers to quitting and/or could allow practitioners to keep up with the contemporary issues related to cannabis (for example: latest jargon utilized by their clients).

Our study has limitations in that we only examined the content of 100 QuitCannabis posts appearing under the Reddit “hot” tab. As with all social networking sites, Reddit is a constantly evolving platform, and so the posts under this tab may vary from day to day. Collecting more posts from all tabs over multiple days may have provided a more holistic snapshot of the posts within this subreddit, and this larger sample size could have impacted our results. Additionally, severity estimates of CUD should be viewed as only suggestive, as the Reddit posts may have omitted one or more symptom criteria and we also have no way of identifying the individuals posting on this subreddit.

Despite popular opinion that cannabis is not addictive, 22,23 QuitCannabis demonstrates the self-reported struggles associated with quitting cannabis use. This exploratory research highlights the potential of online communities such as QuitCannabis as tools for individuals coping with addiction and choosing recovery, and future research should investigate if involvement in such communities would be a beneficial supplement to more traditional recovery practices.

Why Weed and Alcohol Don’t Mix

The scientific explanation for getting the spins.

W e’ve all been there. You’re drinking at home, hiding out from coronavirus while listening to 69 Love Songs and sniffing your ex’s old undershirts. You’re adequately sauced, but not so drunk that you can’t remember all the words to “I Don’t Want to Get Over You.” Then you decide that what this moment really needs is a little bit of weed.

Bad move. As I learned every single weekend from the ages of 18 to 25, the wrong mix of booze and weed can be a toxic combination. Your blood pressure will drop, your stomach will seize, your skin will turn clammy, the color will drain from your face, and the world will start spinning. And that’s before you start puking. What seemed like a good idea at the time can quickly end with your head in the toilet if you’re lucky, and in the bushes if you’re not. It is, to put it mildly, unpleasant.

This doesn’t happen to everyone. Some people can drink a handle of Jim Beam and do half a dozen dabs, and then walk in a straight line and repeat the alphabet backward. We call these people “alcoholics.” But for many of us, adding weed to an already full stomach of booze can be a real party killer.

There’s a pharmacological reason for that, says Scott Lukas, the director of the Behavioral Psychopharmacology Research Laboratory at Harvard, and a man who has spent his career studying the effects of combining recreational drugs.

In 1992, Lukas published a study on what happens when people drink alcohol and smoke weed, and what he found was surprising: Cannabis actually lowers the blood alcohol content by impairing the absorption of alcohol into the bloodstream. In other words, adding THC to the mix kind of sobers you up, while at the same time getting you stoned. In theory, this sounds great, but the problem is what comes next: People tend to increase their alcohol consumption if they aren’t getting as drunk as expected.

“What would somebody do if they drank three beers, which normally makes them tipsy, and all of a sudden they’re not feeling it?” Lukas asked me over the phone. The answer is obvious: Drink more. And this, in turn, can lead to over-intoxication and everything that comes along with it, including the spins, the puking, and the feeling that if the world isn’t ending, it should be.

Interestingly, the effects on THC levels are reversed when combined with booze, which Lukas found in a 2001 study: “When subjects smoked a marijuana cigarette and then drank, the THC concentrations skyrocketed,” he told me.

It’s also less likely to make you sick if done in this order. From my extensive personal experience, this checks out, but what’s the reason behind it? It has something to do with the anti-nausea effects of THC and other cannabinoids—the very things that make weed such an effective treatment for the upset stomach that can accompany chemotherapy or illness.

“It depends on the drugs, the dose, and the order in which you do it,” Lukas said. “If you smoke first, you get the antiemetic [anti- vomiting] effect going on, so that if you drink too much, you won’t get as nauseated.”

Support The Stranger

Of course, the best way to avoid “greening out,” as the phenomenon is called, is to stick with one drug or the other. “The effects are unpredictable enough when doing just one drug,” Lukas said. “When you add a second drug, you add another whole dimension.”

But if you’re going to mix, remember this: Dosage matters. Order matters. As the old adage goes, “Drink to excess and then smoke, and the spins are no joke.”
