Internet Diffusion and Ecstasy Diffusion Across Countries: The Moderating Role of National Anxiety Prevalence
Using a 1996–2021 panel of 149 countries, this study finds that internet diffusion is positively associated with ecstasy diffusion, an effect that is significantly amplified in nations with higher prevalence of anxiety, suggesting that illicit market expansion is driven by the interplay of digital opportunity and population vulnerability.

In the modern world, the internet has reshaped how people connect, trade, and find information. It has lowered the barriers to entering markets, making it easier to buy and sell everything from books to illegal substances. At the same time, societies face a growing burden of mental health challenges, particularly anxiety. When large numbers of people feel anxious, stressed, or overwhelmed, they often seek ways to cope, sometimes turning to substances to relieve their distress. For decades, researchers have studied how technology spreads and how drug use spreads, but they have often looked at these two forces separately. A critical question remains: does the internet simply provide a neutral tool for buying drugs, or does the mental state of a population change how that tool is used? Understanding this relationship is vital because it helps explain why drug markets grow in some places but not others, even when internet access is similar.
A new study by Tariq H. Malik of Liaoning University investigates this exact puzzle. The research analyzed data from 149 countries over a period spanning from 1996 to 2021. The goal was to see if the spread of internet use across a country is linked to the spread of ecstasy, a synthetic drug often used for its mood-altering effects. More importantly, the study wanted to know if the level of anxiety within a population changes that link. The researcher proposed a specific idea: that the internet acts as a kind of amplifier. If a country has high internet access but low anxiety, the internet might not lead to a massive increase in drug trade. However, if a country has both high internet access and high anxiety, the combination could create a perfect storm, where the ease of online access meets a desperate need for relief, causing the drug trade to surge.
The study confirmed that there is indeed a positive connection between how much a country uses the internet and how widespread ecstasy use becomes. As internet penetration grows, the availability and use of the drug tend to rise. This aligns with the understanding that online platforms reduce the difficulty of finding drugs, connecting buyers with sellers, and maintaining anonymity. However, the study found that this relationship is not the same everywhere. The researcher discovered that the level of national anxiety acts as a powerful moderator. In countries where anxiety is low, the link between internet use and drug diffusion is weak; the internet is present, but it does not drive a significant increase in drug trade. But in countries where anxiety is high, the link becomes much stronger. Here, the internet does not just provide access; it fuels a demand driven by the need to cope with psychological distress. The data suggests that when a population is anxious, the internet transforms from a neutral network into a highly effective engine for illicit drug distribution.
The researcher also looked at the shape of these relationships to see if they were simple straight lines or more complex curves. They found that the connection between internet use and drug diffusion accelerates; as internet use gets higher, the increase in drug diffusion gets steeper, especially when anxiety is high. The relationship between anxiety and drug use was even more surprising. The data suggested a U-shaped pattern: at moderate levels of anxiety, drug diffusion was at its lowest. It was only when anxiety became very low or very high that drug diffusion increased. This implies that a certain amount of social stress might not immediately trigger a drug market, but once anxiety crosses a critical threshold, the drive to find relief through substances becomes much more potent.
To ensure these findings were solid, the researcher tested the results in many different ways. They checked if the results held up when they looked at data from previous years or future years, and they tested whether the pattern remained true even when they adjusted for other factors like economic freedom, government corruption, and military spending. They also used advanced statistical methods, including an instrumental-variable specification, though the paper notes these results should be interpreted with caution. In every case, the core finding remained consistent: the internet and anxiety work together. The study concludes that technology-enabled drug markets are not just a result of better connectivity. They are the product of a specific combination of digital opportunity and human vulnerability. This means that efforts to stop the spread of online drug markets cannot rely on monitoring the internet alone. To be effective, prevention strategies must also address the underlying mental health conditions that drive people to seek relief in the first place. The study suggests that without understanding the emotional state of a population, we cannot fully understand how digital tools reshape illicit trade.
