Marijuana is known to induce orthostatic hypotension-like symptoms, such as dizziness and fainting, when upright position. We investigated changes in cerebral blood velocity (CBV) and peripheral circulation during upright posture in 10 right-handed males with a history of marijuana consumption.
- Before the trial, the individuals had been physically and psychologically sound and drug-free for at least three months.
- The CBV, blood pressure, and pulse rate of the middle cerebral artery were measured in the reclining and standing positions, before and after smoking a high-potency marijuana cigarette or a placebo cigarette on 2 different laboratory visits.
The subjects were asked about vertigo while in an upright position. Six of ten marijuana-exposed patients experienced moderate to severe vertigo while standing, but not placebo-exposed subjects. Subjects who had severe vertigo while standing demonstrated significant drops in blood pressure and cardiac output.
Could marijuana cause convulsions?
Cannabinoids attach to certain receptors in the brain known as CB1 and CB2 receptors, therefore treating epilepsy. In turn, these receptors limit the release of neurotransmitters such as glutamate, which stimulate the central nervous system and can cause seizures.
At a blood alcohol concentration of 0.15, unconsciousness is likely. This is approximately double the legal limit in most states for driving. A brain malfunction is the cause of an intoxicated blackout. Your brain ceases storing your actions as memories.

- This indicates that you may be disoriented and unable to recall what occurred just before or after the seizure.
Once the post-ictal state has subsided, your recollection of the events will often return within 5 to 30 minutes. The leading cause of fainting is a transient reduction in blood pressure. When blood pressure falls too low, the heart cannot pump enough blood to the brain, resulting in loss of consciousness.
This is known as syncope, and its causes include: Inflammation or stimulation of the vagus nerve. This is likewise known as vasovagal syncope. When the vagus nerve is activated, the heart rate and blood pressure might decrease, resulting in fainting. This can occur when urinating, getting blood drawn, receiving an injection, or feeling intense emotions.
Standing too rapidly You may have felt dizzy when you stood up too soon. In addition, some people faint from doing this. This condition is known as orthostatic hypotension. Internal hemorrhaging. Internal bleeding can cause a reduction in blood pressure.
- Heart issues.
- Several cardiac disorders, including irregular pulse and valve dysfunctions, can induce fainting. Epilepsy.
- In addition to blackout, seizures can also produce fainting and complete loss of consciousness.
- If you have frequent fainting, you should see a doctor to rule out an underlying health concern.
You should also consult your doctor if you have a history of and fainting. Fainting during physical activity is uncommon and may be reason for alarm.

Typically, how long does fainting last?
Fainting Heat, discomfort, anguish, the sight of blood, anxiety, and hyperventilation are common reasons of fainting. Typically, repositioning the patient will improve their condition. Frequent episodes of fainting must be explored medically to determine underlying reasons.
A brief period of unconsciousness brought on by an abrupt decrease in This quick dip is most likely due to either a shift in the blood vessels or the pulse itself. To maintain a consistent blood pressure, blood arteries continuously change their width. When we stand up, for instance, our blood vessels constrict (tighten) to combat the forces of gravity.
Temporary may be produced by a number of events that cause blood vessels to dilate (expand), such as or. Insufficiency of blood flow to the brain results in loss of consciousness. Most instances of fainting are transient and non-serious. Typically, a fainting episode lasts only a few seconds, however it causes the individual to feel terrible and recovery might take several minutes.
