A study on ‘energy boosting’ substance/nootropics consumption by medical trainees during examinations in India.
This cross-sectional study of 245 Indian medical trainees reveals that examinations drive the widespread use of neuroenhancing substances like coffee, energy drinks, and modafinil primarily for wakefulness and concentration, with convenience and peer influence as key drivers and prolonged use linked to significant adverse effects and dependence risks.

Imagine your brain as a high-performance race car. Usually, it runs perfectly on its own fuel, but sometimes, when the track gets really tough—like during a massive, stressful exam—you might feel like you need a little extra boost to keep the engine humming. This is the world of "neuroenhancement," a fancy term for people using substances to give their brains a temporary upgrade. Think of it like adding a turbocharger or a nitro boost to your mental engine. Some of these boosts are everyday things like coffee or tea, which are like reliable, mild fuel additives. Others are stronger, prescription-only medicines designed to keep you awake or sharpen your focus, which are more like high-octane racing fuel. The big question researchers have been asking is: when the pressure is on, do students reach for the mild additives, the heavy-duty fuel, or a mix of both? And more importantly, what happens to the engine if they keep pouring in the boosters for too long?
This study zooms in on medical students in India, a group known for facing some of the most intense academic marathons in the world. The researchers wanted to see what happens in the "pit stop" of exam season. They asked 245 trainees, aged 18 to 30, about their habits. They weren't just looking for who drank coffee; they wanted to know why they drank it. Was it to stay awake (like keeping the car running through the night) or to boost concentration (like tuning the engine for a faster lap)? They also looked at two main categories of "boosters": the common "energy boosters" like coffee, tea, and energy drinks, and the "nootropics" or smart drugs, specifically a medication called Modafinil, which is usually meant for sleep disorders but is sometimes used off-label to stay alert.
The results paint a picture of a student body running on a very specific diet. The most popular "fuel" by far was coffee. About 79% of the students used coffee to stay awake during exams, and roughly 65% used it to sharpen their focus. Tea was the second most popular, followed closely by caffeine-based energy drinks. Interestingly, while coffee was the crowd favorite, a significant chunk of students—about 14%—were using Modafinil. This is notable because, in India, Modafinil is supposed to be a prescription-only medicine, yet it was being used by a large number of students without a doctor's note, likely because it lasts longer than coffee (keeping the "engine" running for 12 to 15 hours compared to coffee's 4 to 6 hours).
The study also dug into the "cost" of this extra fuel. Out of all the students surveyed, nearly 80% admitted that the stress of exams was the main reason they started using these substances. The researchers found that while many students felt these boosts helped them stay productive, there was a catch. When students reported negative side effects—like headaches, jitteriness, or stomach issues—these problems were much more likely to happen after using the substances for a long time (over three years) rather than just once. It's like driving a car with a nitro boost: it might feel great for a single race, but if you keep slamming the pedal for years, the engine starts to sputter.
The environment played a huge role, too. The study found that living in dorms or hostels was a major factor. It seems that when you are surrounded by friends and seniors who are all doing the same thing, it becomes the "normal" way to study. About 40% of students said their friends influenced them, and 15% said seniors set the example. The main reason students gave for choosing these substances over other methods, like just sleeping more or studying differently, was simply "convenience." It was the easiest, quickest way to get the job done.
However, the authors are careful not to say this is a "win" for the students. They point out that while many students believe these substances make them more productive, the data suggests that relying on them for years can lead to dependence and health risks. In a country like India, where there is a high risk of Type 2 diabetes, the high sugar content in those energy drinks adds another layer of danger. The study concludes that while these substances are a common tool for surviving exam stress, they come with real risks, especially when used as a long-term crutch rather than a one-time fix. The authors suggest that we need to talk more about these habits, not just to stop them, but to understand why students feel they need them in the first place.
