Can Drugs Cause Stroke? Cambridge Study Finds Higher Risk
Imagine a young and healthy individual who, without warning, is no longer able to speak, move, or think. This is what can happen after a stroke, and research is revealing that the use of recreational drugs can greatly increase the risk, even for younger adults.
A recent study conducted by a leading institution from the University of Cambridge revealed that drugs like cannabis, cocaine, and amphetamines may increase the risk of a stroke to a larger extent than imagined.
The researchers studied data on more than 100 million individuals, making it one of the biggest studies ever done on drug use and stroke risks.

Togglewhat is recreational drugs?
Recreational drugs are substances people use for pleasure, relaxation, or mood changes and not for medical purposes. These drugs affect the brain and nervous system, changing how a person feels, thinks, and behaves.
Examples of recreational drugs
- Cannabis (Marijuana) – for relaxation and to change moods.
- Cocaine – A stimulant, increases energy and alertness.
- Amphetamines – Increases concentration and boosts energy levels.
- MDMA (Ecstasy) – Produces feelings increased energy.of happiness, emotional closeness,and increased energy.
- LSD (Lysergic Acid Diethylamide) – This is a powerful psychedelic drug that affects perception, thoughts, and feelings.
- Alcohol and Nicotine – These are also considered to be a part of the list of recreational substances.
Research Finds Strong Link Between Recreational Drugs and Stroke Risk
Recent research published in the International Journal of Stroke has found alarming facts about the use of recreational drugs and the risk of having a stroke. A team of scientists has found some of the commonly used drugs can greatly increase the risk of having a stroke, which can cause permanent brain damage, disability, or even death.
Cocaine and Stroke Risk
According to this study, cocaine use has the effect of increasing the risk of stroke by 96%. This means, that people using cocaine are almost twice as likely to have a stroke compared to people not using the drug.
Cocaine has powerful effects on the body. It stimulates the nervous system, leading to an abrupt increase in heart rate and blood pressure. This sudden change can cause extreme strain on the blood vessels in the brain.As a result of this, a number of harmful processes may occur, such as:
- The blood vessels may suddenly constrict, which would cut down on the flow of blood to the brain.
- The blood pressure may suddenly increase, which would lead to more bleeding in the brain.
- The drug can disturb heart rhythm, which may cause blood clots to form and travel to the brain.
Amphetamines effects on the brain
The study indicated that people who used amphetamines were at a 122% higher risk of stroke compared to people who did not use these drugs. This implies that people who used amphetamines were at more than twice the risk of having a stroke compared to people who did not use the drugs. Amphetamines can cause increased risk of stroke through:
- Rapid increases in high blood pressure, which can harm blood vessels.
- Inflammation of the inside lining of blood vessels, which can weaken them.
- Narrowing of arteries, which may reduce blood flow to the brain.
- Increased heart workload, which may lead to clot formation.
Cannabis
Cannabis showed a smaller but still significant effect.This study discovered that cannabis use leads to an increased stroke risk of 37%.Although many people consider marijuana harmless, scientists are discovering more and more evidence of its effects on the cardiovascular system and brain circulation.The possible mechanisms include:
- Changes in blood pressure and heart rate.
- Increased blood clotting, which can block brain arteries.
- Decreased oxygen supply to brain tissue.
- Inflammation of the blood vessels.
Some studies have also suggested that it can cause large artery stroke, which is caused by blockage of major arteries supplying blood to the brain.
Stroke Risk in People Under 55
When the researchers studied individuals under the age of 55, the results were even more alarming.
Among younger users:
- Use of amphetamine almost tripled the stroke risk (174%).
- Use of cocaine increased the stroke risk by 97%.
- Use of cannabis increased the stroke risk by 14%.
This challenges the common belief that stroke mainly affects older adults.Today, doctors are seeing more strokes in young adults, and drug use may be one of the reasons.
Why Can Drugs Trigger a Stroke?
According to researchers, recreational drugs can impact the human body in the following dangerous ways:
Causes sudden spikes in blood pressure: Recreational drugs tend to be powerful stimulants. For example, drugs like cocaine and amphetamines can increase blood pressure rapidly.When blood pressure suddenly increases:
- The walls of the blood vessels get stressed and weakened.
- Small blood vessels in the brain may break or burst.
- Long-term damage to arteries may occur.
Blood Vessel Spasms: Some of these drugs can cause the blood vessels in the brain to suddenly tighten and narrow. This is called vasospasm.When a vasospasm occurs:
- Blood vessels suddenly constrict or get smaller.
- Blood flow to part of the brain stops or slows down.
- Brain cells begin to die due to lack of oxygen.
Disruption of Heart Rhythm:Recreational drugs can also affect the normal rhythm of the heart, which is known as arrhythmias.When the heart rhythm becomes irregular:
- Blood may collect inside the heart.
- This pooled blood can form clots.
- This clot can travel through the bloodstream and reach the brain.
Scientists Warn the Drugs Themselves May Raise Stroke Risk
The researchers were interested in answering an important question: Do drugs actually cause strokes, or is it the unhealthy lifestyle, which often accompanies the use of drugs, that leads to an increased risk of having a stroke?
To find the answer, they employed a scientific method called Mendelian randomization. This method helps scientists to look at whether or not a particular factor really causes a disease, rather than just being linked to it.
The results of the study indicated that the drugs themselves may cause stroke, not just the lifestyle factors.
Experts Speak About the Findings
Dr. Megan Ritson from the Stroke Research Group said the study’s results are very important. She explained that this research is one of the largest and most detailed studies ever done on how recreational drugs may increase the risk of stroke.
Another scientist, Eric Harshfield, said the results of the study indicate that the recreational drug could be causing the stroke, and the unhealthy lifestyle choices are not the main factor.
He said the results of the study indicate that if drug use could be cut down, then the number of strokes worldwide could be cut down as well.
Can stroke be prevented ?
One of the interesting things about stroke is that many of its risk factors are preventable. Doctors say that lifestyle plays a huge role, including:
- Diet: : Fruits, vegetables, and whole grains support healthy blood vessels.
- Physical activity: Physical activity helps improve circulation of the blood and heart health.
- Smoking:Smoking damages blood vessels and greatly increases stroke risk.
- Maintain a healthy weight: Being overweight also increases the risk of stroke and heart disease.
- Limit alcohol intake:Too much alcohol can raise stroke risk.
- Manage diabetes:Regulating blood sugar levels helps prevent blood vessels from being damaged.
- Reduce drug use: Staying away from recreational drugs helps in reducing the risks of stroke.
Conclusion:
Recreational drugs such as cocaine, amphetamines, and cannabis may also increase the risk of stroke by a huge margin, even among younger individuals. Studies published in the International Journal of Stroke highlight how recreational drugs may damage blood vessels and increase blood pressure, which can lead to severe or life-threatening strokes.
