Canadian Journal of Addiction (CJA-JCA)
Journal Canadien d'Addiction (CJA-JCA)

Online Submission and Review System (Updated November 2020)

The Canadian Journal of Addiction (CJA-JCA) is a peer reviewed journal devoted to practical clinical research, management and treatment related to addictive disorders and their behaviors. The journal publishes broad-spectrum, patient-oriented coverage of all aspects of addiction, directed toward an audience of addiction medicine clinicians, primary care providers, psychiatrists, clinical psychologists, pharmacists, and other health care practitioners involved in alleviating the consequences of the misuses of alcohol and licit and illicit drugs as well as addictive behaviours. CJA is intended to portray the Canadian experience but also welcomes international submissions relevant to Canadian practice.

A submitted manuscript must be an original contribution not previously published (except as an abstract or preliminary report), must not be under consideration for publication elsewhere, and, if accepted, must not be published elsewhere in similar form, in any language, without the consent of CJA's editors. Each person listed as an author is expected to have participated in the study to a significant extent. Although the editors and reviewers make every effort to ensure the validity of published manuscripts, the final responsibility rests with the authors, not with the Journal, its editors, or the publisher.

Terminology: Throughout, the word sex denotes biological variable based upon chromosomal assignment, and generally male, female and intersex. Gender is a constellation of sociocultural processes that interact with and have the potential to influence human biology.

Patient anonymity and informed consent: It is the author's responsibility to ensure that a patient's anonymity be carefully protected and to verify that any experimental investigation with human subjects reported in the manuscript was performed with informed consent and following all the guidelines for empirical research with human subjects required by the institution(s) with which all the authors are affiliated.

Conflicts of Interest: Authors must state all possible conflicts of interest in the manuscript, including financial, consultant, institutional and other relationships that might lead to bias or a conflict of interest. If there is no conflict of interest, this should also be explicitly stated as none declared. All sources of funding should be acknowledged in the manuscript. All relevant conflicts of interest and sources of funding should be included on the title page of the manuscript with the heading “Conflicts of Interest and Source of Funding:"

Permissions: Authors must submit written permission from the copyright owner (usually the publisher) to use direct quotations, tables, or illustrations that have appeared in copyrighted form elsewhere, along with complete details about the source. Any permission fees that might be required by the copyright owner are the responsibility of the authors requesting use of the borrowed material, not the responsibility of CJA-JCA.

Equity, Diversity and Inclusion: The Canadian Journal of Addiction values and is committed to diversity and inclusion in publishing.  Submissions from a diverse range of authors from across all backgrounds are encouraged.


Original Research: Typically, articles will contain new data derived from a sizable series of patients or subjects. The text cannot exceed 3,500 words (which does not include an abstract of no more than 250 words), a maximum of 5 tables and figures (total), and up to 40 references. Word count includes only the main body of text (i.e., not tables, figures, abstracts or references). Additional tables or figures can be submitted in a separate file as supplemental data for posting online. Submissions must be in compliance with ethical standards. For reporting of clinical trials, please consult

Review: Review articles are usually solicited by the Editors, but we will consider unsolicited material. Please send an outline to the editorial office for approval before writing a Review for CJA-JCA. The text cannot exceed 4000 words with an abstract of no more than 250 words, a maximum of 5 tables and figures (total), and up to 70 references. Word count includes only the main body of text (i.e., not tables, figures, abstracts or references). Additional tables or figures can be submitted in a separate file as supplemental data for posting online. Submissions must be in compliance with ethical standards. For further guidelines, please consult

Clinical Case Column: The presentation of one or two anonymous patient cases, followed by discussion from different clinical viewpoints on how best to assess, diagnose, and treat the patient shall serve to translate research findings into clinical practice. New findings such as side effects and disease manifestations that may suggest a change in practice are required and should be highlighted. The case may represent a real patient or an amalgamation of actual patients synthesized into a single case to enhance teaching. Either approach should be clearly stated in the manuscript. In the case of a real patient, written consent of the patient should be collected and kept by the author and this should be stated in the cover letter.  The word count for a Clinical Case Column cannot exceed 3,500 words, and the references should not exceed 20. Submissions must be in compliance with ethical standards. For further guidelines, please consult

Editorial and Commentary: These Opinion pieces are written solely by the Editor(s) or invited author(s).  The topics addressed may include articles in the current or recent issue, issues currently before the addiction community, or other topics at the Editor's discretion. The text cannot exceed 1500 words, with up to 20 references.

Brief Research Report: Preliminary reports, case reports and secondary studies from previous publications of no more than 1500 words total (not including structured abstracts, acknowledgements, references, tables, and figures), with a maximum combined total of 3 figures and tables.

Letters to the Editor: Ideally, Letters to the Editor are in reference to an article previously published in CJA-JCA, but may also focus on current topics of relevance. The text cannot exceed 500 words, no more than one table or figure, and up to 10 references. Word count includes only the main body of text (i.e., not tables, figures or references).

Book Reviews: Authors may be invited to review books in the Addiction field of interest to the CJA-JCA. Book Reviews must be no more than 1,500 words (including publication information, reviewer rating, body text, and references). Tables and figures are not accepted. Direct quotes should include page numbers in the reference.

Peer-Review: All submissions will be reviewed by Editors. Only manuscripts of sufficient quality that meet the aims and scope of the Canadian Journal of Addiction will be sent out for two peer-reviews.  The assigned Editor may consider only one of the names that the submission authors may provide as suggestions for a peer-reviewer for their particular topic.

Online manuscript submission: All manuscripts must be submitted to:  

Manuscripts that do not adhere to the following instructions will be returned to the corresponding author for technical revision before undergoing peer review.

General format: Submit manuscripts in English, 8 1/2 x 11-inch (21 x 28-cm) with at least a 1-inch (2.5-cm) margin on all sides. Double space all copy, including legends, footnotes, tables, and references.

 Title page: Include on the title page (a) complete manuscript title; (b) authors' full names, highest academic degrees, and affiliations; (c) name and address for correspondence, including telephone number and e-mail address; (d) address for reprints if different from that of corresponding author; and (e) sources of support that require acknowledgment.
The title page must also include disclosure of funding received for this work.

Structured Abstract and Keywords: Limit the abstract to 250 words. Do not cite references in the abstract. Limit the use of abbreviations and acronyms. Use the following subheads: Objectives, Methods, Results, and Conclusions. List three to five keywords.​

Text: If applicable, organize the manuscript into main headings. Define abbreviations at first mention in the text and each table and figure. If a generic medication is cited, follow with a brand name in brackets. Acknowledge all forms of support, including pharmaceutical and industry support, in an Acknowledgments paragraph.

References: References must be double-spaced and numbered consecutively as they are cited using a superscript number. References first cited in a table or figure legend should be numbered so that they will be in sequence with references cited in the text at the point where the table or figure is first mentioned. List all authors when there are six or fewer; when there are seven or more, list the first three, followed by “et al."  The reference style follows the AMA format rather than the format of APA.  The following are sample references:

​Numbered references to personal communications, unpublished data, or manuscripts either “in preparation" or “submitted for publication" are unacceptable. If essential, such material can be incorporated at the appropriate place in the text. Referenced preprints are acceptable.

Figures & Figure legends: Digital art should be created/scanned and saved and submitted as a TIFF (Tagged Image File Format) or JPEG (Joint Photographic Experts Group). PPT (PowerPoint) files will also be accepted. Brief and specific Legends must be submitted for all figures and should appear on a separate manuscript page after the references.

Tables: Cite tables consecutively in the text, and number them in that order. Key each on a separate sheet, including the table title, appropriate column heads, and explanatory legends (including definitions of any abbreviations used). Do not embed tables within the body of the manuscript. They should be self-explanatory and should supplement, rather than duplicate, the material in the text.

Acknowledgements: Authors may thank people who were involved with specific content of the work but who do not qualify as authors (people who referred patients; assisted with data collection, statistical analysis, or writing; or supervised and provided general support).

Corrections: It is the author's responsibility to ensure that there are no errors in the submissions. Changes made to conform to journal style will stand if they do not alter the authors' meaning. Only the most critical changes to the accuracy of the content will be made. The publisher reserves the right to deny any changes that do not affect the accuracy of the content.


Respecting the Farmington Consensus, the peer-review process will screen for attempted or actual instances of duplicate publication, plagiarism or scientific fraud.  When the above is brought to our attention post-publication, the Editorial Board will review the allegations and publish an appropriate disclaimer. The Editor in Chief may inform the host institution of the author of the issue.

The Journal follows the Core Practices as outlined in the COPE (Committee on Publication Ethics) Guidelines. Journals and publishers should have robust and well described, publicly documented practices in regards to misconduct allegations, authorship, appeals process, conflict of interest policies, reporting guidelines, ethics, management, peer review process and corrections.
