What Is Greening Out? The Symptoms, Causes, and Risks
As cannabis use becomes more common, many people encounter the term “greening out.” But what is greening out, what does greening out feel like and is greening out dangerous? Understanding this experience can help users recognize its symptoms, reduce risks and seek help if cannabis use becomes problematic.
What Is Greening Out?
Greening out is a term used to describe the negative physical and psychological effects some people experience after consuming too much THC (tetrahydrocannabinol), the active compound in cannabis. Similar to alcohol intoxication, greening out can cause nausea, dizziness, paranoia and loss of coordination.
Greening out typically happens when someone consumes too much cannabis too quickly, especially with high-potency strains, edibles or concentrates. Since THC affects the brain’s endocannabinoid system, overloading it can lead to distressing side effects.
What Does Greening Out Feel Like?
The symptoms of greening out vary from person to person but often include:
- Dizziness and lightheadedness – Individuals may feel faint, disoriented or unsteady.
- Nausea and vomiting – Many users report an upset stomach or intense nausea.
- Rapid heart rate (tachycardia) – THC can temporarily increase heart rate, leading to anxiety or panic attacks.
- Extreme fatigue or drowsiness – Some people experience sudden, overwhelming tiredness.
- Sweating and chills – The body may react with cold sweats or shivering.
- Paranoia and anxiety – THC can trigger heightened anxiety, panic attacks or feelings of doom.
- Loss of coordination – Standing or walking may become difficult due to dizziness.
For some, greening out feels similar to alcohol poisoning, making it a distressing experience. These effects can last anywhere from 30 minutes to several hours, depending on the amount and method of cannabis consumption.
Is Greening Out Dangerous?
While greening out is not usually life-threatening, it can be extremely unpleasant and, in some cases, dangerous.
Potential Risks of Greening Out:
- Accidents and injuries – Dizziness and disorientation can lead to falls, car accidents or other injuries.
- Heart complications – Cannabis increases heart rate, which can be risky for individuals with underlying heart conditions.
- Severe panic attacks – Some people experience extreme paranoia or psychosis, which can be frightening and disorienting.
- Choking or aspiration – Vomiting while under the influence increases the risk of choking or aspiration pneumonia.
How to Prevent Greening Out
To reduce the chances of greening out:
- Start low and go slow – Use small amounts, especially if consuming edibles, which take longer to kick in.
- Stay hydrated and eat beforehand – Dehydration and low blood sugar can worsen symptoms.
- Avoid mixing substances – Combining cannabis with alcohol or other drugs increases the risk of negative effects.
- Know your limits – Some people are more sensitive to THC than others.
What to Do If You or Someone Else Greens Out
If you or someone else is greening out:
- Stay calm – The effects will wear off, but panic can make it feel worse.
- Lie down and breathe slowly – Deep breaths can help manage anxiety.
- Stay hydrated – Drink water, but avoid caffeine or alcohol.
- Get fresh air – A cool, quiet space can ease symptoms.
- Seek medical help if necessary – If symptoms are severe, persistent or involve heart issues, call 911 or seek medical assistance.
