Using someone else's ADHD stimulant to study or work: what NIDA and reviews say about risks, what is known about benefit, and where to turn for help. Non-judgmental information.
Content last updated . This page has not been medically reviewed.
Urgent first
Call 911 (US) if someone has chest pain, a very fast or irregular heartbeat, a seizure, confusion, extreme agitation, or a very high body temperature after taking a stimulant. NIDA lists dangerously high body temperature and an irregular heartbeat as possible results of high stimulant doses. [1] Poison Help in the US is 1-800-222-1222. If you are in distress or having thoughts of harming yourself, call or text 988. [2]The question
Many people feel pressure to keep up. This page is for students, workers and parents who have heard that prescription stimulants such as those used for ADHD can help people study or work, and want to know what is actually known. It is not a judgment and it gives no amounts or ways to use these medicines. Stimulants are prescription medicines for a doctor to decide on.Evidence labels used here: insufficient evidence, evidence of harm, Proper evidence not found.
What these medicines are for
NIDA says stimulants are prescribed for only a few conditions, including ADHD and narcolepsy. [1] MedlinePlus lists the amphetamine-type medicine as part of an ADHD treatment program. [3] For people with a diagnosis, the right amount and monitoring are decided by their prescriber. See ADHD in adults.What research found
| Question | What the source found | Strength |
|---|---|---|
| How common is non-prescribed use? | A systematic review of 111 studies found self-reported rates in population samples ranging from 2.1% to 58.7%, with most studies examining college students. [4] | Wide range, differing definitions |
| Does it improve grades or work in people without ADHD? | The review found little evidence that academic performance is improved in people without ADHD, even though improving performance was the most common reason people gave. [4] | Insufficient evidence |
| Is it harmful? | The review found most use linked to no or minor medical effects, but adverse outcomes, including death, occur in some people. [4] NIDA lists addiction, cardiovascular events and psychosis as potential risks of non-medical use for cognitive enhancement. [1] | Evidence of harm in some people |
| Workplace-specific data | NIDA says some professionals report using stimulants to increase productivity. [1] Rates and outcomes at work: Proper evidence not found in the sources we read (NIDA, PubMed review, MedlinePlus). | Not established |
A study in people with ADHD does not tell us what happens in people without it, and the reverse is also true. We make no claim about effects in healthy adults beyond what the review above stated.
Dependence and withdrawal
NIDA says people can become dependent on or addicted to prescription stimulants, and that stopping can bring fatigue, depression and disturbed sleep. [1] Repeated misuse of some stimulants can lead to hostility, paranoia or even psychosis. [1] MedlinePlus says the amphetamine-type medicine can be habit-forming. [3]Sharing and selling
MedlinePlus warns that selling or giving away the medicine may harm others and is against the law, and advises storing it where nobody else can take it. [3]Interactions, pregnancy, heart, and who should ask first
NIDA lists cardiovascular events among the risks of non-medical use. [1] Stimulants can also interact with other medicines. We did not read a complete interaction list for this page; ask a pharmacist (see medication interactions). Pregnancy, breastfeeding, teenagers and older adults need clinician guidance before any stimulant. This is not a decision to make from a website.Where to get help
- Already taking non-prescribed stimulants and want to stop or are worried? Speak with a doctor, campus health service or pharmacist. Do not change a medicine prescribed to you without asking your prescriber.
- Struggling to focus? Attention problems can come from sleep, stress, mood, other medicines or ADHD. Start at Focus & Memory and Medicines, sleep, mood and illness that affect memory and focus; an ADHD evaluation is a clinician's job.
- Crisis or emotional distress: call or text 988 (US). [2]
- Problems after any product: tell a clinician; the FDA also takes adverse-effect reports through MedWatch. [5]
- Supplements for studying are covered separately: Supplements for students and exam performance and Prescription ADHD stimulants vs supplements.
Frequently asked questions
Do ADHD stimulants help students without ADHD?
A systematic review found little evidence that academic performance improves in people without ADHD. [4]
Is borrowing a friend's prescription dangerous?
It can be. NIDA lists addiction, cardiovascular events and psychosis among the risks, and MedlinePlus says sharing the medicine may harm others and is illegal. [1][3]
How common is it?
Self-reported rates in population samples ranged from 2.1% to 58.7% in a review, partly because studies define it differently. [4]
What if I already take someone else's pills?
Speak with a doctor or pharmacist, and do not make changes to a prescribed medicine without your prescriber. NIDA notes stopping can cause fatigue, depression and disturbed sleep. [1]
Where can I get emotional support?
In the US, call or text 988. [2]
