Greening out is a term that has become more common as marijuana use becomes increasingly prevalent. It refers to a form of marijuana overdose that can result in uncomfortable and sometimes alarming symptoms. Understanding what greening out is, recognizing its symptoms, and knowing how to prevent and manage it are essential for anyone who uses or is around cannabis.

What is Greening Out?

Greening out occurs when someone consumes too much cannabis, leading to a variety of unpleasant physical and psychological symptoms. This phenomenon is different from other forms of overdose because it primarily involves marijuana. While it is not typically life-threatening, it can be very distressing and may require medical attention in severe cases.

Symptoms of Greening Out

People who green out may experience a range of symptoms. Dizziness, nausea, and vomiting are common physical reactions. Additionally, increased heart rate, anxiety, and panic attacks can also occur. These symptoms are the body’s reaction to consuming an excessive amount of THC, the psychoactive component of marijuana. Psychological effects might include anxiety or paranoia, making the experience even more uncomfortable.

Causes of Greening Out

Several factors can lead to greening out. Consuming high doses of cannabis, especially products with high potency, is a primary cause. Edibles are particularly notorious for causing greening out because they take longer to affect the body, leading individuals to consume more than intended. Smoking or vaping large amounts can also lead to these symptoms. Different cannabis products have varying levels of THC, and lack of awareness about these levels can increase the risk of greening out.

Risks Associated with Greening Out

While greening out is not usually dangerous, it can lead to significant discomfort and health risks. The immediate physical symptoms can be severe enough to cause dehydration or fainting. Psychological symptoms like panic attacks can be particularly distressing and may exacerbate existing mental health conditions. It’s important to recognize these risks and take steps to mitigate them.

Prevention and Management

Preventing greening out involves a few simple strategies. First and foremost, moderation is key. Start with small amounts and wait to see how your body reacts before consuming more. Be aware of the potency of the marijuana product you are using. Staying hydrated can help manage some of the physical symptoms. If you are using cannabis for the first time or trying a new product, it’s important to be aware of its effects and stay in a safe environment.

If someone you know is greening out, it’s crucial to stay calm and help them manage their symptoms. Ensure they are in a comfortable, safe place. Encourage them to lie down and drink water. Seeking medical attention is advisable if symptoms are severe or do not improve, particularly if there are signs of severe anxiety, panic attacks, or uncontrollable vomiting.

Treatment Options

For most people, the symptoms of greening out will pass with time and rest. Staying hydrated, lying down in a calm environment, and avoiding further cannabis use until symptoms subside are basic steps. Over-the-counter medications can help manage symptoms like nausea. In severe cases, seeking medical attention is important. Medical professionals can provide support and treatment to alleviate symptoms and ensure there are no serious health risks.

Long-Term Considerations

Repeated episodes of greening out could indicate a marijuana use disorder. It’s important to be aware of your consumption habits and consider seeking help if you find yourself frequently experiencing these symptoms. Marijuana abuse can lead to dependence and other health issues over time. Awareness and moderation are key to preventing these outcomes. Understanding your limits and the potency of the cannabis products you are using can help reduce the risk of greening out.

Marijuana Addiction

Marijuana addiction, also known as cannabis use disorder, occurs when individuals become dependent on marijuana, using it daily or nearly every day despite negative consequences. This type of drug abuse can lead to significant impacts on one’s physical and mental health, affecting daily life and relationships. Addiction may develop as users seek the therapeutic effects initially provided by marijuana, but over time, the compulsive need for the drug takes over. Treatment services, including rehab and detox programs, are essential for those struggling with addiction to regain control and improve their overall well-being.


Greening out, or experiencing a marijuana overdose, is an unpleasant and sometimes frightening consequence of consuming too much cannabis. Recognizing the symptoms and knowing how to manage them can help reduce the discomfort associated with this condition. Awareness and moderation are crucial in preventing greening out. If you or someone you know is struggling with marijuana abuse, it’s important to seek help. Call Virtue Recovery Houston at 866-457-4811 for support and guidance.
