From prejudice to marginalization
This study investigates online hate speech in Finland, particularly Twitter messages targeting people of Muslim faith and the LGBTQ+ community, using a mixed-methods approach that combines quantitative text classification with a BERT model and qualitative thematic analysis via BERTopic and examination of highly interacted posts from 2018 to 2023. The study shows increasing instances of hate speech occurring online, primarily against Muslims, with…
Identifying Risk Factors of Substance Use in Finland
Background: This study explores the dynamics of substance use in Finland, employing Artificial Intelligence (AI) and Machine Learning techniques to identify key risk factors and predict patterns of drug use. Objectives: Using data from the Finnish National Drug Survey and applying 15 feature selection methodologies, this study identifies 23 risk factors associated with the five most used illicit substances: cannabis, ecstasy, amphetamines, cocain…
Closing doors, opening windows – Adaptations and opportunities for harm reduction services during the Covid-19 pandemic in Europe
Background Across Europe, harm reduction services experienced significant disruptions during the COVID-19 pandemic. This study analyses the experiences of harm reduction service providers during the pandemic in 34 European cities, focusing on their main challenges, adaptations, and opportunities for change. A closer examination of Athens and Dublin offers an in-depth look into these experiences.Methods A mixed-methods approach is used, integratin…
Tracing the dynamics of misinformation and vaccine stance in Finland amid Covid-19
This study analyzed 1,683,700 vaccine-related tweets in Finnish using FinBERT language model, Botometer, and BERTopic, from December 2019 to October 2022. A strong correlation was identified between Negative Stance towards Vaccines (NSV) and misinformation, with an upward trend over time and a significant role of malicious bot accounts. Topic modeling revealed persistent themes of vaccine skepticism and diverse misinformation themes adapting to d…
Tripping in the Happiest Country of the World – Use Values of Psychedelics According to Finnish Users
Background The use of psychedelics is on the rise worldwide as more people are experimenting, self-medicating or seeking benefits from these substances.

How far are we? Assessing progress in hepatitis C response towards the WHO 2030 elimination goals by the civil society monitoring in 25 European countries, period 2020 to 2023
BACKGROUND: With the advent of direct acting antivirals (DAAs) the World Health Organisation (WHO) adopted global strategy to eliminate hepatitis C virus (HCV) infection by 2030. In Europe, people who inject drugs (PWID) account for the majority of new cases, however testing and treatment remain suboptimal. The aim was to monitor progress in HCV policy and cascade-of-care for PWID, led by the civil society organisations (CSO) that provide harm re…
Unveiling the Veiled Threat
This article presents the results of a comprehensive study examining the influence of bots on the dissemination of COVID-19 misinformation and negative vaccine stance on Twitter over a period of three years. The research employed a tripartite methodology: text classification, topic modeling, and network analysis to explore this phenomenon. Text classification, leveraging the Turku University FinBERT pre-trained embeddings model, differentiated be…
Setting the misinformation agenda
This research investigates the dynamics of COVID-19 misinformation spread on Twitter within the unique context of Finland. Employing cutting-edge methodologies including text classification, topic modeling, social network analysis, and correspondence analysis (CA), the study analyzes 1.6 million Finnish tweets from December 2019 to October 2022. Misinformation tweets are identified through text classification and grouped into topics using BERTopi…
Identifying factors influencing Covid-19 vaccine uptake in Finland – a qualitative study using social media data
Introduction: Vaccine demand creation requires understanding what is driving the uptake of the vaccine. 24 Qualitative research methods are paramount to gaining a localized understanding of behavioral 25 drivers and barriers to vaccine uptake, but they are often underutilized. Methods: This is a qualitative study that 26 used public comments on the Facebook and Twitter posts of the Finnish Institute for Health and 27 Welfare (THL) as data sources…
Covid-19 risk perception framework of the public
Understanding the risk perceptions of the public is central for risk communications and infodemic management during emergency and preparedness planning as people's behavior depends on how they perceive the related risks. This qualitative study aimed to identify and describe factors related to COVID-19 risk perceptions of the public in Finland and to make this information readily available to those who communicate with the public during crises. Th…
The Complexity of Drug Consumption Room Policy and Progress in Finland
Drug consumption rooms (DCRs) have been established to reach high-risk people who use drugs (PWUDs) and reduce drug-associated harm. Despite effectiveness, their establishment requires strong advocacy and efforts since moral perspectives tend to prevail over health outcomes in many countries. DCRs have generally emerged as a local response to inadequate central government policy. Likewise, the initiative of the Municipality of Helsinki in 2018 op…
The civil society monitoring of hepatitis C response related to the WHO 2030 elimination goals in 35 European countries

With the advent of direct acting antivirals (DAAs) the World Health Organization (WHO) adopted a strategy to eliminate HCV as public health threat by 2030. To achieve this, key policies for PWID must be implemented and HCV continuum of care needs to be moni…
Subtypes of Problem Gamblers, Sociocultural Factors, and Availability of Gambling
Finnish treatment-seeking gamblers were examined in light of predominant problem gambler subtype models. “Psy science” oriented problem gambler subtypes were found to be considerably influenced by gambling cultures and treatment traditions in the countries from which the mainstream problem gambler research originates. Thus, models that emphasize the psychopathology of the individual might cause some friction when applied to countries like Finland…

The Harm-Reduction School of Thought
Despite its relatively long history in the international drug policy field, the meaning of the term harm reduction is still disputed. From a description of the different actor-based footings of the international harm-reduction school of thought, the analysis concludes that the diverse conceptualizations of harm reduction are to be understood as interpretive frameworks that are functionally different according to the different types of actors and …
