New study cautions marijuana beginners to 26 adverse reactions
Researchers documented the most common negative side effects of smoking weed, and who might be most susceptible.
- A team of researchers identified a total of 26 possible adverse reactions to cannabis use.
- Coughing fits, anxiety, and paranoia are among the top three most common adverse reactions to smoking weed.
- It was the people who smoke on a less frequent basis who were more likely to have had the bad experiences.
"She's fine! She'll be okay." I remember calling down to a concerned pedestrian strolling past my apartment early one evening back in college as my friend gasped and vomited on our porch, brought to her knees by a violent coughing fit after having just huffed a joint of cannabis. And she was okay! (Eventually.) But new research affirms that these types of experiences, which range from unpleasant to deeply distressing, are relatively common for people new to smoking pot.
The most common adverse effects of pot
As it turns out, coughing fits are among the top three most common adverse reactions to cannabis use, along with anxiety and paranoia, according to a new study published in the Journal of Cannabis Research.
Now that weed is legal in the state, a team of researchers at Washington State University sought to document potential negative reactions to cannabis in order to paint a detailed picture of the effects of smoking weed for newbies. The authors surveyed more than 1,500 college students on the specific type and frequency of adverse reactions they had experienced while using pot. Additionally, the students in the study were surveyed about their demographics, personality traits, reasons for using cannabis and their use patterns.
Despite marijuana's numerous benefits, the team identified a total of 26 possible adverse reactions to the drug. More than half of the study participants reported having coughing fits along with anxiety and/or paranoia while using cannabis. The most frequently occuring of these were the coughing fits, along with chest/lung discomfort and body humming. A subset of the study group reported these reactions occurring around 30–40% of the time they were using pot. On the flip side, the three least-commonly reported reactions to cannabis use were fainting, visual hallucinations and cold sweats.
"There's been surprisingly little research on the prevalence or frequency of various adverse reactions to cannabis and almost no research trying to predict who is more likely to experience these types of adverse reactions," said Carrie Cuttler, assistant professor of psychology and an author on the paper, according to WSU News. "With the legalization of cannabis in Washington and 10 other states, we thought it would be important to document some of this information so that more novice users would have a better sense of what types of adverse reactions they may experience if they use cannabis."
The most distressing of the 26 negative reactions were panic attacks, fainting, and vomiting. Yet, the survey data suggested that cannabis users generally do not find even acute adverse reactions to cannabis to be severely distressing.
What causes a bad reaction?
So, who is most likely to experience the negative reactions? Interestingly, one thing the researchers didn't find to correlate with a bad reaction to cannabis was the quantity of use during a single session. Rather, it was the people who smoke on a less frequent basis who were more likely to have had the bad experiences. Additionally, individuals who reported using cannabis to fit in with their peers, had a history of displaying problematic use of the drug or had anxiety sensitivity—a tendency to catastrophize the bodily sensations that come with anxiety—were more likely to report negative side effects from cannabis use and experience more intense levels of distress. Although, Cuttler noted that these associations were small and nothing was strongly related to these experiences.
One curious correlation Cuttler found after reanalyzing the data was that certain personality traits on the Big Five personality model more frequently experienced one of the more rare reactions to the drug.
"[I] found that the personality traits extraversion and openness to experience predicted the frequency with which people reported experiencing visual hallucinations," she told Big Think. There were, however, no significant predictors of what individuals were more susceptible to experiencing fainting—another rare side effect. In the future, Cuttler thinks it will be important to continue investigations into what other individual difference variables might predict positive vs. negative experiences with cannabis, and to document them at a broader level.
Although the study didn't reveal measures that can be taken to protect against negative effects, Cuttler echoed the common advice given to new users: "Start low and go slow. It's generally a good idea for people to start with lower potency products and to use small amounts at first."
Given its rapid entry into the mainstream over the last few years, it may be time marijuana starts getting treated like other medicinal drugs that come with warning labels. The researchers expressed hope that findings like these will be utilized by doctors and medical cannabis distributors to give users or potential users a clearer idea of the side effects that come with lighting up.
What is human dignity? Here's a primer, told through 200 years of great essays, lectures, and novels.
- Human dignity means that each of our lives have an unimpeachable value simply because we are human, and therefore we are deserving of a baseline level of respect.
- That baseline requires more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose.
- We look at incredible writings from the last 200 years that illustrate the push for human dignity in regards to slavery, equality, communism, free speech and education.
The inherent worth of all human beings<p>Human dignity is the inherent worth of each individual human being. Recognizing human dignity means respecting human beings' special value—value that sets us apart from other animals; value that is intrinsic and cannot be lost.</p> <p>Liberalism—the broad political philosophy that organizes society around liberty, justice, and equality—is rooted in the idea of human dignity. Liberalism assumes each of our lives, plans, and preferences have some unimpeachable value, not because of any objective evaluation or contribution to a greater good, but simply because they belong to a human being. We are human, and therefore deserving of a baseline level of respect. </p> <p>Because so many of us take human dignity for granted—just a fact of our humanness—it's usually only when someone's dignity is ignored or violated that we feel compelled to talk about it. </p> <p>But human dignity means more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose—a freedom that can be hampered by restrictive social institutions or the tyranny of the majority. The liberal ideal of the good society is not just peaceful but also pluralistic: It is a society in which we respect others' right to think and live differently than we do.</p>

The future of dignity<p>Around the world, people are still working toward the full and equal recognition of human dignity. Every year, new speeches and writings help us understand what dignity is—not only what it looks like when dignity is violated but also what it looks like when dignity is honored. In his posthumous essay, Congressman Lewis wrote, "When historians pick up their pens to write the story of the 21st century, let them say that it was your generation who laid down the heavy burdens of hate at last and that peace finally triumphed over violence, aggression and war."</p> <p>The more we talk about human dignity, the better we understand it. And the sooner we can make progress toward a shared vision of peace, freedom, and mutual respect for all. </p>
Scientists find that bursts of gamma rays may exceed the speed of light and cause time-reversibility.
- Astrophysicists propose that gamma-ray bursts may exceed the speed of light.
- The superluminal jets may also be responsible for time-reversibility.
- The finding doesn't go against Einstein's theory because this effect happens in the jet medium not a vacuum.

Is Bitcoin akin to 'digital gold'?
- In October, PayPal announced that it would begin allowing users to buy, sell, and hold cryptocurrencies.
- Other major fintech companies—Square, Fidelity, SoFi—have also recently begun investing heavily in cryptocurrencies.
- While prices are volatile, many investors believe cryptocurrencies are a relatively safe bet because blockchain technology will prove itself over the long term.

After all, skeptics have long doubted the ability of cryptocurrencies to go mainstream as a form of everyday payment. But people seem increasingly comfortable with digital payment systems.</p><p style="margin-left: 20px;">"The entire world is going to come into digital first," Schulman said at Web Summit, adding that PayPal's services already go hand-in-hand with cryptocurrencies. "As we thought about it, digital wallets are a natural complement to digital currencies. We've got over 360 million digital wallets and we need to embrace cryptocurrencies."</p><p>Sanja Kon, vice president of global partnerships at the cryptocurrency payments processor company UTRUST, also spoke at Web Summit about the increasing adoption of digital payments:</p><p style="margin-left: 20px;">"Physical cash is becoming more and more obsolete. And the next step in the evolution is digital currency."</p><p>Kon noted some of the inherent advantages of cryptocurrencies, namely ownership. </p><p style="margin-left: 20px;">"For many people, this is really the main benefit of cryptocurrency: Users owning cryptocurrencies are able to control how they spend their money without dealing with any intermediary authority like a bank or a government, for example," Kon said, adding that there are no bank fees associated with cryptocurrencies, and that international transaction fees are significantly lower than wire transfers of fiat currency.</p><p>Kon said cryptocurrencies have unique growth opportunities in areas where people aren't integrated into modern banking systems:</p><p style="margin-left: 20px;">"With cryptocurrencies and blockchain, with the use of just a smartphone and access to internet, Bitcoin and cryptocurrencies can be available to populations of people and users without access to the traditional banking system."</p>
Bitcoin as 'digital gold'<p>Still, it could take years for people to start using cryptocurrencies for everyday purchases on a large scale. Despite this, many cryptocurrency advocates see digital currencies, particularly Bitcoin, as a way to store value—digital gold, essentially.</p><p style="margin-left: 20px;">"I don't think Bitcoin is going to be used as a transactional currency anytime in the next five years," billionaire investor Mike Novogratz recently told <a href="https://www.bloomberg.com/news/articles/2020-10-23/novogratz-says-bitcoin-is-digital-gold-not-a-currency-for-now?srnd=markets-vp" target="_blank">Bloomberg</a>. "Bitcoin is being used as a store of value. [...] "Bitcoin as a gold, as digital gold, is just going to keep going higher. More and more people are going to want it as some portion of their portfolio."</p><p>There are obvious parallels between gold and Bitcoin: Both are mined, do not degrade over time, are finite in supply, and aren't directly tied to the value of fiat currency, making them <a href="https://www.reuters.com/article/us-gold-inflation/gold-as-an-inflation-hedge-well-sort-of-idUSKCN1GD516" target="_blank" rel="noopener noreferrer">relatively invulnerable to inflation</a>. The obvious objection is that the price of Bitcoin, and cryptocurrencies in general, is far more volatile than gold.</p><p>But for investors who believe the inherent value of cryptocurrency technology will prove itself over the long term, these price fluctuations are just bumps on the long road to the future of currency. </p><p style="margin-left: 20px;">"It's no longer a debate if crypto is a thing, if Bitcoin is an asset, if the blockchain is going to be part of the financial infrastructure," Novogratz said. "It's not if, it's when, and so every single company has to have a plan now."</p>
A new study finds that some people just want privacy.
- Despite its reputation as a tool for criminals, only a small percentage of Tor users were actually going to the dark web.
- The rate was higher in free countries and lower in countries with censored internet access.
- The findings are controversial, and may be limited by their methodology to be general assumptions.
