A student crams for exams on three hours of sleep, then borrows a friend’s Ritalin to push through one more all-nighter. A young professional starts taking a few extra tablets to keep up with a punishing workload. Neither of them sees it as drug use. The pills came from a pharmacy, after all, and plenty of people around them are doing the same thing. That is exactly what makes prescription stimulants so easy to misuse, and so easy to underestimate.
These medicines have a real and valuable place in healthcare. The problem starts when they move outside the prescription that was written for a specific person, at a specific dose, for a genuine medical reason.
What prescription stimulants actually are
Prescription stimulants are medicines used mainly to treat narcolepsy and Attention Deficit Hyperactivity Disorder (ADHD). The ones you are most likely to come across include:
- Methylphenidate (Ritalin, Concerta)
- Amphetamine and dextroamphetamine (Adderall)
- Lisdexamfetamine (Vyvanse)
- Dexmethylphenidate (Focalin, Attenade)
As the name suggests, they stimulate the body. They lift energy, alertness and concentration, and they push up heart rate, blood pressure and breathing rate. Taken at higher doses than prescribed, or by someone they were never meant for, they can also produce a pleasurable high. That combination of sharper focus and a mood lift is what draws people toward using them in ways a doctor never intended.
Why students reach for them
In South Africa, the conversation about Ritalin misuse keeps coming back to one group: students. The pressure to perform is intense, the marks feel like they decide everything, and a tablet that promises a few more hours of focus can seem harmless. It is not.
This is not a vague worry. Research published in the South African Journal of Psychiatry, looking at medical students at the University of the Free State, found that around 11% of those surveyed were using methylphenidate at the time of the study. Most were taking it to study harder rather than to treat a diagnosed condition, and fewer than a third had ever been diagnosed with ADHD. In other words, the bulk of the use was non-medical. If that is the picture among medical students, who understand the risks better than most, it tells you something about how normalised this has become on campuses.
The danger is that “just for exams” rarely stays that way. The brain learns quickly, and what starts as an occasional study aid can become something a person feels they cannot perform without.
How stimulants change the brain
Amphetamine, methylphenidate and similar medicines work through a process that is strikingly close to the way illicit drugs like cocaine and methamphetamine work. They cause a buildup of neurotransmitters called monoamines, mainly dopamine and noradrenaline, in the brain and spinal cord.
Noradrenaline drives the body’s fight-or-flight response. When levels climb, heart rate and breathing speed up and the liver releases stored glucose for a quick burst of energy. Dopamine does something different but just as important. It regulates alertness and feeds into the brain pathways that handle reward and motivation.
Normally, dopamine rewards things that help us survive, like eating a good meal, spending time with people we care about, or exercising. That small lift makes us want to do those things again. Stimulants flood the same system artificially. Over time, the brain can start to treat the drug as more rewarding than ordinary life, which is the heart of how dependence takes hold. The United States National Institute on Drug Abuse explains this reward-pathway effect in its overview of prescription stimulants, and it applies just as much here as anywhere else.
Tolerance: needing more for the same effect
When someone uses a stimulant heavily over a long period, the body adapts. It takes a larger dose to get the effect that a smaller dose used to give. That is tolerance, and a rising need for the drug is often one of the first physical signs that use is becoming a problem.
Doctors manage this carefully. They may rotate medications or build in a “drug holiday” of a few days or weeks to keep tolerance in check. Someone misusing stimulants on their own has none of that oversight. They tend to push the dose up to chase the original feeling, and that climbing dose pulls them toward the next stage, which is craving.
Cravings and why they linger
Because stimulants hijack the brain’s reward and motivation circuits, long-term misuse can train the brain to treat the drug as essential, not just enjoyable. When use stops suddenly, intense cravings can follow. People describe them feeling almost physical, like hunger or thirst.
That intensity is what makes recovery hard. Even when a person can see the damage, the lost job, the strained relationships, the wish to stop can be overwhelmed by the craving. Cravings can also arrive out of nowhere, triggered by a place, a person or a situation linked to past use. This is one of the main reasons relapse is such a risk for someone who has only recently stopped.
How the drugs are misused
Taken as prescribed, these medicines come as pills or tablets that release a controlled, therapeutic dose. People who misuse them recreationally often take more than recommended to chase a stronger high, and some go further with far riskier methods, such as:
- Crushing the pills and snorting them
- Dissolving them in a drink
- Dissolving them in solution and injecting
These methods sharply raise the risk of overdose and other serious harm. Some newer medicines, such as lisdexamfetamine (Vyvanse), are designed so that crushing the tablet does not release a bigger dose, which helps reduce this kind of abuse. There is also an observed link between stimulant misuse and tobacco use, even though evidence that mixing stimulants with other drugs increases their addictive pull is limited.
When does use become addiction?
Use stops being casual when the body comes to depend on the drug to function. After a long period of misuse, the body no longer works the same way without it, and stopping abruptly will almost always bring on withdrawal.
Addiction usually shows up in daily life long before anyone names it. Someone may feel unable to handle ordinary responsibilities at work or at home without the drug. They might feel real anxiety or dread at the thought of being without it. Hobbies and friendships that once mattered can start to feel pointless. When a substance comes to feel essential to getting through the day, or even to feeling okay, walking away becomes genuinely difficult. Prescription stimulant misuse can also sit alongside anxiety or depression, which is why dual diagnosis treatment often matters so much.
What withdrawal looks like
Withdrawal symptoms depend on how long and how heavily a person has been using. They can include:
- Strong cravings for the drug
- Feeling flat or unable to enjoy anything (anhedonia)
- Irritability and anxiety
- A noticeably bigger appetite
- Low energy
- Disrupted sleep, whether insomnia or sleeping too much
- Depression
Some people feel these for weeks or even months after their last dose. The symptoms usually ease on their own in time, but medical support during this stretch matters. It helps prevent relapse driven by sheer discomfort, and it protects against the more dangerous low moods that can include thoughts of self-harm. A supervised detox takes that risk seriously rather than leaving someone to white-knuckle it alone.
Relapse is a particular danger during these long withdrawal periods. Weeks after stopping, an everyday situation tied to past use can still set off a craving. The triggers are different for everyone, but common ones include:
- Stress at work
- Conflict with family or partners
- Being around the people or places linked to old drug use
How prescription stimulant addiction is treated
Because prescription and illicit stimulants act on the brain in such similar ways, treatment borrows from approaches developed for cocaine and methamphetamine. There are no SAHPRA-approved medicines made specifically to treat stimulant addiction, so treatment leans on behavioural therapies, usually after a period of medically supervised detox.
Common approaches include:
- Cognitive Behavioural Therapy (CBT). This helps people recognise the situations that spark cravings, think through the consequences before acting, and build coping strategies for hard moments. You can read more about how CBT works in rehabilitation and why it has become a backbone of stimulant treatment.
- Contingency management. This uses tangible rewards, such as vouchers earned for drug-free urine tests, to reinforce staying off the drug. It has a solid track record with stimulant addiction.
Alongside outpatient and inpatient options, some people benefit from longer stays in therapeutic or sober-living communities, often six to twelve months or more, where they can rebuild independence while staying inside a drug-free environment. Whatever the setting, recovery is something a person keeps working at rather than a box ticked at discharge. The patterns behind prescription drug misuse share a lot with other medicine-related dependencies, and our piece on when anti-anxiety pills become a problem looks at that overlap.

Frequently Asked Questions
Is Ritalin really addictive if it comes from a pharmacy?
Yes. The source does not change the chemistry. Methylphenidate affects the brain’s dopamine system in a way that is closely related to illicit stimulants, so it can lead to tolerance, cravings and dependence when used outside a proper prescription or at higher doses than directed.
Can you become addicted just from using it to study?
It can start there. Many people who misuse stimulants begin with occasional use around exams or deadlines. The risk is that the brain adapts, the dose creeps up, and what felt like a harmless study aid becomes something a person struggles to stop. Studying without it can begin to feel impossible.
What should I do if I think my child or partner is misusing stimulants?
Approach it with care rather than confrontation. Watch for the signs covered above, such as a rising need for the drug, mood changes and pulling away from things they used to enjoy. Then talk to a professional. South Africa’s free 24-hour Substance Abuse Helpline, run with SADAG, is reachable on 0800 12 13 14, and you can speak to our team confidentially as well.
Is medical detox necessary?
Stimulant withdrawal is not usually life-threatening in the way alcohol withdrawal can be, but it can bring heavy depression and self-harming thoughts. Supervised support makes that safer and helps prevent an early relapse driven by how unpleasant withdrawal feels.
