About this Research Topic

Background

Cannabis has been used in even the oldest traditional medicines available. In the last century, somewhat negative attention has prevailed when it comes to the psychotropic and abusive effects and for this reason Cannabis has been banned and considered illegal in many countries. In recent years, however, there has been a more in-depth evaluation of the legalization of cannabinoids for medical use in several countries following heightened media attention and reports of effectiveness, although not always thoroughly backed up by scientific evidence. In fact, up to now the results from studies discussing the efficacy of the medical use of Cannabis are sometimes contradictory and not always conclusive. Some factors fueling this inconclusiveness include the heterogeneous nature of the studied populations, different Cannabis preparations and dosages, studies with uncontrolled settings and different routes of administration. Moreover, these uncertainties are partly derived from legislative restrictions which, over time, have severely limited the conduction of rigorous, controlled, and comparable studies.

The official introduction of pharmaceutical grade Cannabis inflorescences for medicinal purposes has allowed physicians and pharmacists respectively to legally prescribe and prepare several Cannabis preparations. Such products are currently being administered to patients without their efficacy being evaluated in controlled studies: for each patient the composition and route of administration may be different. In addition, many advanced administration systems have been developed or are still under development, but few clinical trials have been completed.

This Research Topic welcomes submission of Original Research and Review articles focusing on the in-depth analysis of the legal, technological and pharmacological aspects related to the medical use of chemically characterized Cannabis-based formulations. Studies carried out in the past or still in progress will also be considered to assess what evolution there has been in using Cannabis to treat diseases or conditions.

We invite submissions dealing with the following themes, including but not limited to:
• Cannabis based formulations: current and future applications in therapy.
• Legal, technological, and pharmacological aspects related to the medical use of Cannabis.
• Non-clinical evidence supporting therapeutic applications of Cannabis.

Important note for Authors : Only studies dealing with highly purified, chemically characterized Cannabis containing formulations, where the chemical structure and purity must be precisely described by appropriate analytical methods will be considered for review in Experimental Pharmacology and Drug Discovery. The following studies can be accepted for review in Ethnopharmacology: (I) Clinical Trial articles will be accepted for review only in the case that they are randomized, double-blinded, and placebo controlled. (II) Any studies relating to advanced formulations or galenic preparations to better evaluate the potential effects of their application in future therapies.

All the manuscripts submitted to the collection in the Ethnopharmacology Section will need to fully comply with the Four Pillars of Best Practice in Ethnopharmacology (you can freely download the full version here).

Keywords: Cannabis, formulations, effectiveness, medical use, clinical trials, pharmacological actions

Important note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

• Who leads a Research Topic? 

  A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

  The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

• What is the role of a topic editor?

  As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

   

  You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

• What support will I receive when editing a new Research Topic? 

  As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters.
