Germany will legalize cannabis — but nobody knows when

Smoking weed should eventually become legal in Germany. The political will is there. But actually implementing it is hampered by international law, bureaucracy and tax rules. Activists want the process sped up.

An estimated 4 million people in Germany consume cannabis regularly

Cannabis has become a part of everyday culture in Germany and now, policymaking. The coalition government of center-left Social Democrats (SPD), environmentalist Greens and neoliberal Free Democrats (FDP) stated clearly: "We are introducing the controlled supply of recreational cannabis to adults in licensed shops."

To turn these words into practical policies, however, is proving to be a monumental task.

It involves almost every federal government ministry. And the fact that so many bodies are involved makes the legislative process very complex, the government's drug and addiction commissioner Burkhard Blienert told DW. "It encompasses agriculture, youth protection, policing, tax issues and much more," he said.

"The goal is a coherent concept that makes it possible for adults to obtain cannabis in licensed specialty shops, ensuring health protection and the protection of minors."

Germany has seen street demonstrations in favor of legalizing cannabis

Millions of consumers mean billions in tax

It is a concept that will affect many people. Dusseldorf-based economist Justus Haucap told DW an estimated 4 million people consume cannabis in Germany, most of them only occasionally. "We tried to evaluate what that means in terms of the quantity of cannabis. We expect a market volume of about 400 tonnes, which is valued at between €4 billion and €5 billion," he said.

In a report last year, Haucap calculated the possible revenues from taxes and social security contributions, as well as the savings made by the police and judiciary (from no longer prosecuting users) as adding up to almost €5 billion per year. He presented these numbers to an expert hearing at the Ministry of Health earlier this year.

For five days, about 200 experts from Germany and abroad, including Haucap, came together to discuss cannabis legalization —  from representatives of the Permanent Working Group of Highest State Health Authorities (ALOG) to the German Hemp Association and the Customs Criminal Investigation Office (ZKA).

Also in attendance was Dirk Heitepriem, vice president of the Cannabis Business Industry Association (BvCW). "The most surprising thing for me was that we hardly ever discussed the 'if,' only the 'how'", Heitepriem told DW. He described the exchanges between the various groups, "who have quite different interests," as open, collegial and constructive.

Cannabis sale and production could be a source of income for the German government too

Ambitious roadmap

The way forward is as ambitious as it is open-ended. "The agreement is that the federal government will adopt key points in the fall and will draft a law on this basis. It will then be deliberated in parliament. I anticipate this will happen next year. When the law will be passed and come into force: That is in the hands of the parliament," drug commissioner Blienert said.

Until then, many questions need to be resolved. A key one: Where does cannabis come from?

Industry representative Heitepriem sees little room for international trade and importing from traditional growers such as Morocco or Lebanon. "The UN conventions stand in our way, as do European regulations," Heitepriem said, adding: "We assume that there will need to be in-country production, at least initially. This requires massive investment and, above all, a lead time of 1 1/2 to two years to provide the necessary production capacities."

Medical cannabis is produced under strict health and safety regulations

UN conventions a sticking point

The UN drug conventions are also of concern to Burkhard Blienert. "So far, the international agreements have been read in such a way that cannabis is to be strictly prosecuted," he notes, pointing out that one of the relevant UN conventions dates to the 1960s. "It was a different time. But if you now want to move into a new time, with new policies around drugs and addiction that also serve modern health policies, then it is necessary to conduct debates and discussions —  including on how these agreements are to be understood in 2022."

In its most recent annual report in March, the International Narcotics Control Board (INCB), which monitors the UN drug conventions, made clear: "Measures to decriminalize the personal use and possession of small quantities of drugs are consistent with the provisions of the drug control conventions." At the same time, they maintained that legalizing the entire supply chain from cultivation to the consumer contravenes the drug control conventions.

Nevertheless, two countries —  Uruguay and Canada —  have already legalized the cultivation, trade and distribution of cannabis, as have 21 states in the US. These breaches of the UN rules have not brought about any significant consequences. The economist Haucap sees a strong international movement toward cannabis legalization.

Because Germany is the most populous country in Europe, its neighbors are following developments with great interest, according to Haucap: "If Germany creates a legal market for cannabis, I think it would send a very positive signal."

A cautious approach from the opposition

Before that can happen, it is likely that a law must be passed not only by the Bundestag but also by the Bundesrat — the upper house of parliament comprising representatives of the 16 federal states. That includes states where the conservative Christian Democrats (CDU) are in government. In the Bundestag, the CDU is the main opposition party and traditionally the biggest opponent of legalizing cannabis. However, according to Justus Haucap, the CDU is no longer united on this issue. "There are those who think legalization is sensible," the economist concluded, following private conversations with politicians.

This impression was confirmed to DW by CDU parliamentarian and Bundestag health committee member Erwin Rüddel. "I know more and more party colleagues who are taking an increasingly nuanced view and saying, 'there is this extensive drug use.' That is why we need to provide safe access for those who want to consume cannabis recreationally. We will gain more control of the drug problem this way than by turning a blind eye to it," he said.

Call for decriminalization now

Although all signs point toward legalization, a cannabis consumer gets caught in the net of the police and judicial system every three minutes. The authorities must continue to apply the narcotics law. It may be years before licensed specialty shops have cannabis on their shelves. That is why activists are calling for the consumption of cannabis to be decriminalized immediately as a first step, something provided for in the UN conventions.

The background to this demand is exemplified by the latest report on drug-related crime from the Federal Criminal Police Office: When people fall foul of the law because of cannabis, only one in six cases has to do with drug dealing — about 30,000 of the almost 190,000 cases are so-called "consumption-related offenses." It is not the big fish being caught in the net of prohibition, but the stoners.

Burkhard Blienert is critical of the call for immediate decriminalization. "I want a regulated market. Decriminalization goes along with that," emphasized the drug commissioner. "It is better not to break things down into individual elements now, but instead to think everything through together. We want a comprehensive result."

Assessing the toxicity of Reddit comments

Peer-Reviewed Publication

PEERJ

Researchers analyze over 2 billion posts and comments from cross-community Redditors to assess how toxicity changes depending on the community in which they participate

New research, published in the Open Access journal PeerJ Computer Science, which analyses over 87 million posts and 2.205 billion comments on Reddit from more than 1.2 million unique users, examines changes in the online behavior of users who publish in multiple communities on Reddit by measuring “toxicity”.

User behavior toxicity analysis showed that 16.11% of users publish toxic posts, and 13.28% of users publish toxic comments. 30.68% of users publishing posts, and 81.67% of users publishing comments, exhibit changes in their toxicity across different communities – or subreddits - indicating that users adapt their behavior to the communities’ norms.

The study suggests that one way to limit the spread of toxicity is by limiting the communities in which users can participate. The researchers found a positive correlation between the increase in the number of communities and the increase in toxicity but cannot guarantee that this is the only reason behind the increase in toxic content. 

Various types of content can be shared and published on social media platforms, enabling users to communicate with each other in various ways. The growth of social media platforms has unfortunately led to an explosion of malicious content such as harassment, profanity, and cyberbullying. Various reasons may motivate users of social media platforms to spread harmful content. It has been shown that publishing toxic content (i.e., malicious behavior) spreads--the malicious behavior of non-malicious users can influence non-malicious users and make them misbehave, negatively impacting online communities.

“One challenge with studying online toxicity is the multitude of forms it takes, including hate speech, harassment, and cyberbullying. Toxic content often contains insults, threats, and offensive language, which, in turn, contaminate online platforms. Several online platforms have implemented prevention mechanisms, but these efforts are not scalable enough to curtail the rapid growth of toxic content on online platforms. These challenges call for developing effective automatic or semiautomatic solutions to detect toxicity from a large stream of content on online platforms,” say the authors, PhD (ABD) Hind Almerekhi, Dr Haewoon Kwak and Professor Bernard J. Jansen.  

 

“Monitoring the change in users’ toxicity can be an early detection method for toxicity in online communities. The proposed methodology can identify when users exhibit a change by calculating the toxicity percentage in posts and comments. This change, combined with the toxicity level our system detects in users’ posts, can be used efficiently to stop toxicity dissemination.”

 

The research team, with the aid of crowdsourcing, built a labeled dataset of 10,083 Reddit comments, then used the dataset to train and fine-tune a Bidirectional Encoder Representations from Transformers (BERT) neural network model. The model predicted the toxicity levels of 87,376,912 posts from 577,835 users and 2,205,581,786 comments from 890,913 users on Reddit over 16 years, from 2005 to 2020. This study utilized the toxicity levels of user content to identify toxicity changes by the user within the same community, across multiple communities, and over time. For the toxicity detection performance, the fine-tuned BERT model achieved a 91.27% classification accuracy and an Area Under the Receiver Operating Characteristic Curve (AUC) score of 0.963 and outperformed several baseline machine learning and neural network models. 

 

 

TikTok girds for US election misinformation threat

TikTok is putting out word to 'creators' that its ban on political ads includes sponsored videos related to the coming US midter
TikTok is putting out word to 'creators' that its ban on political ads includes 
sponsored videos related to the coming US midterm election.

TikTok on Wednesday rolled out its battle plan against the deluge of misinformation expected to accompany the upcoming US midterm elections, a problem tech firms largely decide themselves how to handle.

The November contest that will decide who controls Congress will generate innocently shared false information as well as deliberate attempts to mislead on the major social media networks—which have begun announcing how they will fight back.

TikTok began reminding users that its ban on  includes videos that people are paid to create for the platform, head of US safety Eric Han said in a blog post.

"If we discover political content was paid for and not properly disclosed, it is promptly removed from the platform," Han said.

TikTok has rolled out an "Elections Center" that will help users know how and where to vote, and feature videos intended to encourage people to think critically about online content, he added.

The widely popular video sharing app will add links to its Elections Center to content identified as being related to the  along with accounts belonging to governments, politicians or political parties.

TikTok will use automated systems and human fact-checkers to assess the accuracy of content, prompting users to "reconsider" sharing posts with unsubstantiated information, Han said.

Fair Election Center's Campus Vote Project, one of the organizations working with TikTok, is helping provide information for registering and voting, said national director Mike Burns.

"We saw historic youth and student voter turnout in the 2018 and 2020 elections," Burns said.

TikTok has emerged as a top social media platform for US teens, according to a recent Pew Research report.

Facebook parent Meta this week said that the safeguards it is putting in place for the midterms will build on lessons learned.

"As we did in 2020, we have a dedicated team in place to combat election and voter interference while also helping people get reliable information about when and how to vote," Meta president of global affairs Nick Clegg said Tuesday in a blog post.

Meta security operations will fight  and domestic influence campaigns, and include new measures to help keep poll workers safe, Clegg said.

Meta will remove misinformation about the , poll results or the integrity of balloting and prohibit new election-related ads during the final week in the campaign, he added.

"We are once again prepared to respond to content discussing the integrity of the election by applying labels that connect people with reliable information," Clegg said.

NASA scientists study how to remove planetary “photobombers”

Imagine you go to a theme park with your family and you ask a park employee to take a group photo. A celebrity walks by in the background and waves at the camera, stealing the focus of the photo. Surprisingly, this concept of “photobombing” is relevant to astronomers looking for habitable planets, too.

When scientists point a telescope at an exoplanet, the light the telescope receives could effectively be “contaminated” by light from other planets in the same star system, according to a new NASA study. The research, published in the Astrophysical Journal Letters on Aug. 11, modeled how this “photobombing” effect would impact an advanced space telescope designed to observe potentially habitable exoplanets and suggested potential ways to overcome this challenge.

“If you looked at Earth sitting next to Mars or Venus from a distant vantage point, then depending on when you observed them, you might think they’re both the same object,” explains Dr. Prabal Saxena, a scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who led the research.

Saxena uses our own solar system as an analog to explain this photobombing effect.

“For example, depending on the observation, an exo-Earth could be hiding in [light from] what we mistakenly believe is a large exo-Venus,” said Dr. Saxena. Earth’s neighbor Venus is generally thought to be hostile to habitability, with surface temperatures hot enough to melt lead – so this mixing could lead scientists to miss out on a potentially habitable planet.

Astronomers use telescopes to analyze light from distant worlds to gather information that may reveal whether they could support life. One light-year, the distance light travels in a year, is almost six trillion miles (over nine trillion kilometers), and there are about 30 stars similar to our Sun within roughly 30 light-years of our solar system.

This photobombing phenomenon, in which observations of one planet are contaminated by light from other planets in a system, stems from the “point-spread function” (PSF) of the target planet. The PSF is an image created due to diffraction of light (the bending or spreading of light waves around an opening) coming from a source and is larger than the source for something very far away (such as an exoplanet). The size of the PSF of an object depends on the size of the telescope aperture (the light-collecting area) and wavelength at which the observation is taken. For worlds around a distant star, a PSF may resolve in such a way that two nearby planets or a planet and a moon could seem to morph into one.

If that is the case, the data that scientists can gather about such an Earth analog would be skewed or affected by whatever world or worlds were photobombing the planet in question, which could complicate or outright prevent the detection and confirmation of an exo-Earth, a potential planet like Earth beyond our solar system.

This is a cartoon illustrating the planetary photobombing concept. Photobombers like Mars and the Moon could sneak into a picture of Earth, if you tried to observe it in a way similar to how scientists will try to find and understand potentially habitable worlds outside our solar system.

Saxena examined an analogous scenario in which otherworldly astronomers might be looking at Earth from more than 30 light-years away, using a telescope similar to that recommended in the 2020 Astrophysics Decadal Survey. “We found that such a telescope would sometimes see potential exo-Earths beyond 30 light-years distance blended with additional planets in their systems, including those that are outside of the habitable zone, for a range of different wavelengths of interest,” Saxena said.

The habitable zone is that region of space around a star where the amount of starlight would allow liquid water on a planet’s surface, which may enable the existence of life.

There are multiple strategies to deal with the photobombing problem. These include developing new methods of processing data gathered by telescopes to mitigate the potential that photobombing will skew the results of a study. Another method would be to study systems over time, to avoid the possibility that planets with close orbits would appear in each other’s PSFs. Saxena’s study also discusses how using observations from multiple telescopes or increasing the size of the telescope could reduce the photobombing effect at similar distances.

Discovering exoplanets and determining if any can support life is part of NASA’s mission to explore and understand the unknown, to inspire and benefit humanity.

The research was funded by NASA under award number 80GSFC21M0002 and was also funded in part by the Goddard Sellers Exoplanet Environments Collaboration (SEEC).
