“Marijuana grays,” or “greening out,” describes a temporary, unpleasant reaction to cannabis that happens when someone consumes more than their body can handle. This experience leads to a specific set of symptoms but is not life-threatening and resolves on its own with time.
The Physical Experience of Marijuana Grays
One of the most recognizable signs of greening out is a sudden paleness of the skin. This is often accompanied by dizziness or lightheadedness, making it difficult to stand, and a wave of nausea that can lead to vomiting.
A cold, clammy sweat is another common symptom. Individuals may experience a significant increase in their heart rate, followed by a sudden drop in blood pressure that intensifies dizziness and weakness. This can also lead to a loss of coordination and a feeling of heaviness in the limbs.
Biological Triggers for Greening Out
The primary biological trigger for greening out is consuming an excessive amount of tetrahydrocannabinol (THC), the main psychoactive compound in cannabis. When THC enters the body, it binds to CB1 receptors in the brain and central nervous system. An overdose of THC overstimulates these receptors, which can cause a sudden drop in blood pressure, a condition known as vasodilation. This drop is largely responsible for the paleness and dizziness associated with the experience.
Several factors increase the likelihood of this reaction.
- Using high-potency cannabis products, such as concentrates or edibles.
- An individual’s tolerance level; new or infrequent users are more susceptible.
- Consuming cannabis on an empty stomach, which can lead to faster absorption.
- Dehydration and mixing cannabis with alcohol.
Managing and Preventing the Reaction
If you experience a green out, find a safe and quiet place to sit or lie down. This minimizes the risk of falling and can help calm feelings of anxiety. Reducing external stimuli like dimming lights can also be beneficial. Sipping water helps with hydration, and a small sugary snack or juice can help stabilize blood sugar levels and alleviate lightheadedness. Focusing on slow, deep breathing can regulate a racing heart and remind you that the feelings are temporary.
To prevent the experience, a cautious approach is effective. The principle of “start low and go slow” is particularly relevant when trying a new or high-potency product. This is especially important with edibles, which have a delayed onset. Other preventative measures include eating a meal beforehand, staying well-hydrated, and avoiding the combination of cannabis with alcohol.
