Greening out refers to a state of discomfort caused by consuming too much THC. It is commonly used to describe an adverse reaction to cannabis, where individuals experience a range of unpleasant physical and psychological symptoms. While not a medically recognized condition, many cannabis users—both new and experienced—can encounter it. The severity of greening out varies from person to person and depends on factors like dosage, individual tolerance, and overall health.
Keep reading to understand what triggers greening out, how to recognize its symptoms, and the best ways to prevent and manage it effectively. For those struggling with cannabis dependence, finding the right addiction treatment option can help regain control and support long-term recovery.
The Science Behind “Greening Out”
The unpleasant effects of greening out stem from how THC interacts with the body’s endocannabinoid system (ECS)—a network that regulates mood, pain perception, appetite, and sleep. When THC binds to cannabinoid receptors, it can overstimulate the ECS, disrupting normal neurotransmitter activity and leading to dizziness, nausea, and anxiety.
One major cause of this phenomenon is THC overload. Consuming excessive THC can throw off the brain’s chemical balance. The more THC binds to cannabinoid receptors, the stronger its effects. In high doses, this overstimulation can overwhelm the body, triggering symptoms commonly associated with greening out.
Not everyone reacts to THC the same way. Factors such as genetics, frequency of cannabis use, and overall health affect how an individual processes THC. Some people have a naturally lower tolerance, making them more prone to greening out, even when consuming the same amount as others.
The way cannabis is consumed plays a big role in how THC is absorbed and processed:
- Smoking or Vaping delivers THC rapidly, leading to quick, intense effects that may trigger greening out.
- Edibles take longer to kick in since they must be digested first. However, their effects last longer and can be much stronger, increasing the risk of overconsumption and a more severe reaction.
By understanding the causes and effects of greening out, cannabis users can make informed decisions and reduce the risk of experiencing these uncomfortable symptoms.
Common Symptoms of “Greening Out”
Symptoms of “greening out” can range from mild to severe and may include:
Physical Symptoms
- Nausea and vomiting
- Dizziness and lightheadedness
- Sweating and chills
- Increased heart rate and palpitations
- Tremors or shaking
- Headache
Psychological Symptoms
- Increased anxiety and paranoia
- Panic attacks
- Disorientation and confusion
- Feelings of impending doom
- Increased sensory sensitivity
- short term memory loss
What Causes “Greening Out”?
Several factors can contribute to greening out, making the experience more intense and uncomfortable.
The higher the THC content in cannabis, the stronger its effects on the body and brain. High-potency strains or concentrates can overstimulate the endocannabinoid system, increasing the risk of greening out.
First-time or occasional cannabis users have a lower tolerance, making them more susceptible to adverse reactions. Their bodies are not yet accustomed to processing THC, which can lead to dizziness, nausea, or anxiety.
Taking in too much cannabis too quickly can overwhelm the body, leading to an overload of THC in the system. This can cause a sudden drop in blood pressure, dizziness, and feelings of panic.
Cannabis effects are often stronger and hit faster when consumed without food. Having an empty stomach can increase THC absorption, intensifying symptoms like nausea or lightheadedness.
Combining cannabis with alcohol or stimulants can amplify its effects, making greening out more likely. Alcohol, in particular, can increase THC absorption in the bloodstream, while stimulants can heighten anxiety and dizziness.
Is “Greening Out” Dangerous?
While “greening out” can be an uncomfortable and distressing experience, it is generally not life-threatening. The symptoms, such as dizziness, nausea, and paranoia, usually subside within a few hours as THC gradually leaves the system. However, for some individuals, particularly those prone to anxiety or panic attacks, the experience can be overwhelming and may require reassurance and support. In rare cases, people with pre-existing heart conditions may face complications due to an increased heart rate. Additionally, greening out can pose other risks, such as dehydration from vomiting or excessive sweating, as well as an increased chance of injury due to impaired coordination, which may lead to falls or accidents.
How to Prevent “Greening Out”?
Prevention is key to avoiding a negative cannabis experience:
- Start Low and Go Slow: If you’re new to cannabis, begin with a small dose and wait before consuming more. This helps you gauge your body’s reaction and avoid overwhelming effects.
- Stay Hydrated: Drink plenty of water before and after consumption.
- Avoid Mixing Substances: Avoid consuming cannabis with alcohol or other drugs. Combining substances can intensify unwanted effects and increase health risks.
- Eat Before Use: Consuming cannabis on a full stomach may reduce its potency. A balanced meal can also help stabilize blood sugar levels and minimize discomfort.
- Choose Low-THC Strains: CBD can help counteract the intensity of THC, leading to a more manageable experience.
What to Do If You “Green Out”?
If you or someone you know is experiencing greening out, follow these steps:
- Stay Calm: Remind yourself that the symptoms are temporary and will pass.
- Find a Quiet and Safe Place: Move to a calm and comfortable environment.
- Hydrate: Drink plenty of water or a soothing beverage.
- Eat Something: If possible, eat a light snack to stabilize blood sugar levels.
- Deep Breathing: Practice deep breathing exercises to calm your nerves.
- Distract Yourself: Engage in relaxing activities, such as listening to music or watching a calming video.
- Seek Support: If you are experiencing severe anxiety or panic, reach out to a trusted friend or family member.
- Use CBD: CBD may help counteract the effects of THC and reduce anxiety.
- Sleep It Off: If possible, take a nap to allow the body to metabolize the THC.
“Greening Out” vs. Other Cannabis-Related Effects
“Greening out” vs. Normal High
A normal high involves pleasurable effects like euphoria, relaxation, and altered perception. “Greening out” involves unpleasant symptoms like anxiety, paranoia, and physical discomfort.
“Greening out” vs. Cannabinoid Hyperemesis Syndrome (CHS)
CHS is a rare condition characterized by cyclical vomiting, nausea, and abdominal pain in long-term, heavy cannabis users. Unlike “greening out,” CHS symptoms can persist for extended periods and require medical intervention.
“Greening Out” and Cannabis Strains
Different cannabis strains have varying effects on the likelihood of greening out:
- High-THC Strains: Strains such as Gorilla Glue, OG Kush, and Amnesia Haze are more likely to cause greening out. Their strong psychoactive effects can overwhelm new or sensitive users, leading to dizziness, nausea, or paranoia.
- CBD-Rich Strains: Strains like Harlequin and ACDC have higher CBD content, which can help mitigate THC’s effects. CBD interacts with THC to counterbalance its intensity, potentially reducing anxiety and discomfort.
- Hybrid Strains: Some hybrids offer a balanced THC/CBD ratio, reducing the risk of greening out. These strains can provide a smoother experience, making them a good option for those who want mild effects without feeling overwhelmed.
Greening Out and Tolerance
Cannabis tolerance varies among users and affects susceptibility to greening out:
- Low Tolerance: New users are at higher risk of greening out. Their bodies are not yet accustomed to THC, making even small doses feel overwhelming.
- High Tolerance: Frequent users may require larger doses but can still experience greening out with excessive consumption. Over time, the body adapts to THC, but pushing limits can still lead to adverse effects.
- Tolerance Breaks: Taking a break from cannabis can reset THC sensitivity, reducing the chances of greening out upon resumption. A short break allows the body to regain sensitivity, making lower doses more effective.
Marijuana Addiction and Treatment
While marijuana addiction may not cause the same physical dependence as opioids or alcohol, psychological dependence can still develop over time. This condition, known as cannabis use disorder, can negatively impact daily life. Common signs of dependence include:
- Difficulty controlling use
- Withdrawal symptoms such as irritability, insomnia, and appetite changes
- Neglecting responsibilities due to cannabis use
- Increased tolerance and reliance on cannabis
For individuals struggling with cannabis dependence, several treatment options are available:
- Cognitive Behavioral Therapy (CBT): This therapeutic approach helps individuals recognize triggers, reframe thought patterns, and develop healthier coping mechanisms to manage their cannabis use.
- Outpatient Programs: Structured outpatient treatment allows individuals to receive counseling, therapy, and support while maintaining their daily routines. These programs provide flexible options for those who need professional guidance without requiring inpatient care.
- Medical Supervision: In cases where withdrawal symptoms or behavioral changes become severe, professional guidance from healthcare providers may be necessary to ensure a safe and effective recovery process.
