The purpose of this paper is twofold. First, it investigates the characteristics of Hanfparade 2022 – the biggest prolegalization festival in Germany – and its visitors, as well as the main reason for participation in Hanfparade. Findings are compared to those from Hanfparade 2016 to explore whether the main reason for festival attendance has changed since the legalization of medical cannabis in 2017 and since the announcement of plans for cannabis legalization. Second, this paper assesses Hanfparade participants’ views on cannabis legalization in Germany, in particular their opinions on and their preferences for retail supply options.

This study is a replication of a research conducted in 2016 at the same festival in Berlin, with a slightly adapted questionnaire. In this study, a combination of qualitative and quantitative research methods was used: observation at the festival, interviews before and after the festival with the organizer and a survey among festival attendees (n = 183).

Protest still looks relevant for the participants at Hanfparade, and the announcement of plans for legalization does not seem to downgrade this feeling. The participants have positive opinions about self-supply through home cultivation, noncommercial supply through Cannabis Social Clubs (CSCs) and commercial supply through stores similar to Dutch coffee shops. However, positive opinions do not necessarily reflect a personal preference, e.g. CSCs were very low in personal preferences. The options of home cultivation and CSCs were more popular among daily users.

This study contributes to the ongoing debate in Germany, focusing on views of cannabis users.

The purpose of this paper is to interrogate if the legal status of a cannabis affects money laundering activity. The legal status of cannabis continues to evolve globally; at the same time, its market remains enormous. Much of this market represents dirty money from criminal acts, which often requires laundering. In the context of changing cannabis regulations, legislation, and policies, the authors propose the possible implications such changes may have on the extent of money laundering.

This paper proposes the implications of the evolution of cannabis regulations on money laundering activities, using the theoretical underpinning of rational choice. Using Australia as a replicable critical case study, the paper, using the Walker gravity model and using United Nations Office on Drugs and Crime-reported prices of cannabis from 2003 to 2017 and Australian Criminal Intelligence Commission reports empirically validates the effects of cannabis regulations on the proceeds available for laundering.

This study finds support for the argument that prohibitive measures toward cannabis use contribute to increases in the need to launder generated proceeds.

The findings can be replicated in other countries and may contribute to novel propositions within the debate on the legalization of cannabis use, which has, thus, far primarily focused on the areas of health, crime, taxation and education.

To the best of the authors’ knowledge, no study has yet attempted to provide an economic analysis of the effects of cannabis policy changes on money laundering.

The COVID-19 pandemic likely impacted cannabis distribution, access and usage worldwide. This study aims to describe self-reported changes in cannabis use and related outcomes following COVID-19-related restrictions among an international sample of people who use drugs.

Using data from the Global Drug Survey COVID-19 Special Edition, the authors identified 20,417 respondents from 13 countries who reported whether the number of THC-containing cannabis usage days changed compared with February 2020 (before COVID-19 restrictions). Using descriptive statistics and a multinomial multivariable logistic regression, the authors investigated the impact of changes in cannabis use on respondents’ mental health, physical health, relationships, finances, work/study performance and cannabis-related pleasure/enjoyment.

Similar proportions of respondents reported that their cannabis use had stayed the same (38.2%) or increased (38.3%) compared with February 2020, while 21.9% of respondents reported a decrease. The most common reason for increased use was having more time (68.4%), while decreased use was associated with having less contact with people they use cannabis with (58.4%). The likelihood of reporting worse mental and physical health, finances, and work/study performance following COVID-19 restrictions was highest among those who reported increased cannabis use.

These findings provide a unique understanding of the short-term international impact of initial COVID-19 restrictions on cannabis use, and highlight the need for policy to address the ongoing and improved provision of evidence-based mental health and other support for people who frequently use cannabis.

To the best of the authors’ knowledge, this is the world’s largest international study exploring the impacts of these changes in cannabis use following initial COVID-19 restrictions on individuals’ mental health, physical health, relationships, finances, work/study performance and cannabis-related pleasure. This study is also unique in comparing these changes across multiple continents.

This study aims to explore people’s experiences of taking cannabis therapeutically and to gather some real-world evidence (RWE) about the products they were using, their efficacy and what kinds of positive or negative effect/s patients experienced. The focus of this discussion is the efficacy of cannabis for the participants in this study.

This was an exploratory study that used a mixed methods approach: a survey and semi-structured interviews. The data presented here focus on thematic analysis of five of the open-ended survey questions. Results from a purposive survey sample are also briefly reported. Interview data are not reported on here.

Across the sample (n = 213), 95.6% of participants reported that taking cannabis helped them with a number of conditions. The most common three themes across the thematic analysis were that cannabis helped with pain relief, sleep and anxiety. Negative effects, some of which related to having to source cannabis from the illicit market, were relatively minor and experienced by 28% (n = 58) of participants. An important finding was that 49% (n = 76) of those who said their use of prescribed medicines had decreased (n = 155), significantly decreased and in some cases stopped their use of prescribed medications.

This study reports on a sample of participants with clinically diagnosed conditions and adds to the RWE base about the efficacy of using cannabis for therapeutic purposes in the New Zealand context.

Innovation ecosystems face many environmental challenges. The literature review shows that innovation ecosystems accelerate innovation activity, but empirical studies have not provided enough case studies focusing on the minimum-waste business strategy as one aspect of the circular economy. Various forms of interaction between members occur in the innovation ecosystems, which determines the level of cooperation. This paper aims to show the structure and forms of cooperation in an innovation ecosystem using the Czech Hemp Cluster (CHC) and its surroundings and suggest research directions in the field of interaction between members in an innovation ecosystem. Although hemp is associated with the production and distribution of narcotics, it is a versatile plant supporting the minimum-waste business strategy.

The research is based on a theoretical part of a literature review of major scientific articles on innovation ecosystems from 2016 to 2021. The case study of the CHC and the hemp ecosystem is based on qualitative research in the form of a content analysis of the mission of the cluster members. In addition to content analysis, the classic multidimensional scaling method and hierarchical cluster analysis were used to reveal ecological guilds.

The case study highlighted the specific relationship between the cluster and the ecosystem. The cluster does not determine the ecosystem boundaries, but the ecosystem is a much broader system of cooperation and interaction between organisations. Clusters emerge after an ecosystem has existed for a particular time to coordinate collaboration and information between organisations and stakeholders. The analysis of the CHC revealed the specific role of non-profit organisations (NPOs) in the innovation ecosystem. NPOs are not engaged in primary functions in the value chain, but they provide supporting activities through coordinated networking, disseminating information on innovation, awareness-raising and stakeholder education. Compared to natural ecosystems, innovation ecosystems are typically characterised by higher forms of collaboration between members.

An exciting opportunity for research on innovation ecosystems is the ecological guilds taken from natural ecosystems and whose identification can help define the boundaries of innovation ecosystems. An opportunity for further research is the comparison of NPO-based and government-based clusters playing a central role in developing innovation ecosystems. Regarding the problematic generalisability of the case study to the entire agricultural production, a challenge is a search for minimum-waste business models in agriculture characterised by the biological nature of production.

Theoretical and empirical studies have not yet considered innovation ecosystems in the minimum-waste context to a sufficient extent. The paper builds on previous scholarly studies focusing on innovation ecosystems and, for the first time, discusses the role of NPOs in the innovation ecosystem. The CHC case study adds a suitable minimum-waste business model to the still very scarce literature on sustainable innovation ecosystems. The article discusses the purpose and forms of cooperation in an innovation ecosystem, identifies a complementarity of roles in the innovation cluster and describes the interrelationship between the cluster and the ecosystem. Discussion of the ecosystem leader in the cluster-based innovation ecosystem shows the differences between Czech, Polish and German life science ecosystems.

The rates of offending and re-offending for young males are higher than any other population. Whilst the UK Ministry of Justice (2020) states that rehabilitation programmes should aim to build a positive identity, little is known about the subjective experiences of how this occurs. Various theories and models suggest that the development of a positive identity assists rehabilitation for young men with convictions (i.e. Johns et al., 2017). Therefore, the current study aimed to gather personal narratives from male, young offenders with the intention of understanding identity development.

Twelve interviews were conducted with young men with convictions aged between 18 and 25 years who had almost completed a rehabilitation process within the community. Narrative analysis was used to analyse the data. All were engaging with the rehabilitation service as a result of conviction for low to medium level offences, including burglary, harm of another person and drug related offences.

Three plots were identified which explain identity when committing offences: “The Powerless”, “The Feared” and “The Disconnected”. One plot was evident within the narratives which explained positive identity when rehabilitated: “The Connected”. The findings illustrate the importance of an approach which considers various aspects of a young offender’s life.

The current study further adds to knowledge base of young offender rehabilitation by providing a systemic understanding of how men with convictions’ identity develop pre- and post-rehabilitation. New implications for trauma informed practice are discussed.

The purpose of this study is to understand the behavior of hybrid bio-composites under varied applications.

Fabrication methods and material characterization of various hybrid bio-composites are analyzed by studying the tensile, impact, flexural and hardness of the same. The natural fiber is a manufactured group of assembly of big or short bundles of fiber to produce one or more layers of flat sheets. The natural fiber-reinforced composite materials offer a wide range of properties that are suitable for many engineering-related fields like aerospace, automotive areas. The main characteristics of natural fiber composites are durability, low cost, low weight, high specific strength and equally good mechanical properties.

The tensile properties like tensile strength and tensile modulus of flax/hemp/sisal/Coir/Palmyra fiber-reinforced composites are majorly dependent on the chemical treatment and catalyst usage with fiber. The flexural properties of flax/hemp/sisal/coir/Palmyra are greatly dependent on fiber orientation and fiber length. Impact properties of flax/hemp/sisal/coir/Palmyra are depended on the fiber content, composition and orientation of various fibers.

This study is a review of various research work done on the natural fiber bio-composites exhibiting the factors to be considered for specific load conditions.
