Summary
Cannabis use is infrequently linked to stroke, unlike other abused drugs. This review explores the limited evidence and potential mechanisms connecting cannabis and stroke.
Area of Science:
- Neurology
- Toxicology
- Public Health
Background:
- Stroke is a known complication of abusing drugs like cocaine and amphetamines.
- Cannabis is widely used, but its association with stroke is rarely reported.
- The causal link and underlying mechanisms between cannabis use and stroke remain unclear.
Purpose of the Study:
- To review existing literature on cannabis use and stroke.
- To explore potential pathophysiological mechanisms linking cannabis to stroke.
- To clarify the association between cannabis consumption and cerebrovascular events.
Main Methods:
- Literature review of studies reporting cannabis use and stroke.
- Analysis of case reports and epidemiological data.
- Examination of proposed biological pathways for cannabis-induced stroke.
Main Results:
- Few studies document cannabis-associated stroke, primarily in younger individuals.
- Evidence for a direct causal relationship is limited and inconclusive.
- Potential mechanisms include effects on blood pressure, heart rate, and vascular reactivity.
Conclusions:
- The association between cannabis use and stroke requires further investigation.
- Cannabis may contribute to stroke risk through various, yet unconfirmed, mechanisms.
- More research is needed to establish causality and understand the impact of cannabis on cerebrovascular health.

01:24CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its effects by...
01:29Stroke: Introduction and Types
A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:21Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.

01:27Regulation of Stroke Volume
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
