If you've ever felt your pleasant high suddenly turn into a racing heartbeat, nausea, and the absolute certainty that something terrible is happening, you've experienced greening out.
We understand how intense and frightening this experience can be, and we're here to help you prevent it from happening again.
The truth is, greening out isn't about taking too much cannabis in total. It's about THC entering your system faster than you can feel and adjust to its effects.
If You're Greening Out Right Now:
STOP consuming immediately
SIT upright (don't lie down)
SIP cold water slowly
BREATHE in for four counts, out for six counts
You're going to be okay. This will pass.

Why Greening Out Feels Intense (But Nobody Actually Dies)
When THC overwhelms your CB1 receptors, your body experiences what we call greening out.
You might feel time slowing down or speeding up, watch yourself from outside your body, or experience a specific type of nausea that's different from alcohol.
Some symptoms rarely get discussed, but are completely normal. These include feeling stuck on the couch, experiencing "the spins" like the room is rotating, or feeling your heart racing.
The Reassuring Facts
No deaths have ever been recorded from cannabis alone. While the experience feels intensely distressing, your symptoms are temporary and typically resolve within 2 to 6 hours.
Your brain isn't permanently damaged, even though it might feel that way.
The conviction that something is seriously wrong is actually a common symptom of greening out itself.

Why Edibles Cause 8 Out of 10 Bad Cannabis Experiences
The 90 to 120-minute onset window creates a perfect trap for overconsumption.
Here's how it typically happens: you take 10mg at 7 pm and feel nothing, so you take another 10mg at 7:45 pm, thinking the first one didn't work.
Both servings crash into your system together around 8:30 pm. Now you're dealing with 20mg when you only intended to feel 10mg, and there's no way to stop what's coming.
The Liver Makes Everything Stronger
When you eat cannabis, your liver converts it into a compound that's roughly four times more psychoactive than what you get from smoking. This explains why a 10mg edible can feel stronger than several joints.
This is exactly why we created our fast-onset micro-dose gummies, which hit in 5 to 15 minutes. When you can feel the effects quickly, you eliminate the dangerous waiting game that causes most bad experiences.
The Only Prevention Method That Actually Works Every Time
We've found one simple framework that consistently prevents greening out: the timer method. Set a timer for 120 minutes after taking edibles or 15 minutes after smoking or vaping.
Honor that timer absolutely, regardless of how you feel. Even if you think nothing is happening, wait until the timer goes off before considering more.
Starting THC Amounts That Keep You Safe
For edibles, start with 2 to 5mg of THC. For the flower, take one small hit and wait.
With vapes, limit yourself to a half-second pull initially. These amounts might seem tiny, but they're your insurance policy against a bad experience.
Why the Timer Method Works
THC stacks invisibly in your system, especially with delayed onset products. You can't feel the first wave building, so you add more thinking and need it.
The timer forces you to wait long enough for effects to manifest fully. This simple discipline prevents the vast majority of greening-out incidents.
How To Roll a Joint | By Mood
What to Do Right Now If You're Currently Greening Out
Stop all consumption immediately and find a quiet, safe space. Sit upright rather than lying down, as lying flat can worsen dizziness and nausea.
Take slow sips of cold water and focus on your breathing. Count four seconds of breathing in and six seconds of breathing out.
Community Remedies That May Help
Many people find relief from chewing black peppercorns, which contain beta-caryophyllene.
Others prefer CBD drops for non-psychoactive comfort or sucking on lemon rinds for the limonene.
While these aren't guaranteed solutions, they provide something active to do while waiting for symptoms to pass. Having a plan helps reduce the feeling of helplessness.
When to Seek Professional Help
Seek immediate assistance if symptoms become severe. Trust your judgment about when you need help.
Remember that professionals have seen this before and can help. There's no judgment in seeking help when you need it.
How Much THC Is Actually in That Hit You Just Took
Most people have no idea how much THC they're actually consuming. A single hit from a joint contains roughly 2 to 7mg of THC, while a rice-grain-sized piece of concentrate packs 25 to 35mg.
A one-second vape pull delivers about 5 to 10mg. These numbers vary based on product potency and individual technique, but they give you a starting reference point.
Why Mixing Changes Everything
Adding alcohol doesn't just increase effects. It fundamentally changes how your body processes THC, often leading to sudden and severe greening out even at THC amounts you normally handle well.
Today's cannabis flower averages 23 to 30% THC. Compare that to 10% from a decade ago, and you understand why your friend's homegrown might hit unexpectedly hard.
Your Friend Is Too High From Weed, and You Need to Help
Use this script: "You're safe, this will pass, I'm staying with you." Repeat it calmly and don't try to explain what's happening in detail.
Keep your voice low and movements slow. Their nervous system is highly alert; sudden sounds or motions can increase distress.
Setting Up the Right Environment
Dim the lights, but don't make it completely dark. Get a cool washcloth for their foreheads, and keep a trash can nearby, just in case.
Play quiet, familiar music if they want it, but silence is fine, too. The goal is to reduce sensory input without making them feel isolated.
Getting Additional Support
Our support team is available from 7 a.m. to 10 p.m. for real-time guidance. Sometimes, talking to someone who understands cannabis's effects provides immediate relief.
Having this resource means you're never alone in managing a difficult situation. We're here to help you through it.
Why That Dispensary Edible Hits Harder Than Three Joints
Edible THC goes through your digestive system and gets processed by your liver differently than smoked THC. This creates effects that aren't just stronger but qualitatively different.
The high lasts longer, feels heavier in your body, and can include effects you never get from smoking.
Understanding this difference helps you respect edibles as their own experience.
Factors That Amplify Effects
Taking edibles on an empty stomach speeds absorption and intensifies effects. Dehydration concentrates THC in your system, making the same amount hit harder.
Your individual metabolism plays a huge role, too.
Fast metabolizers might feel effects in 30 minutes, while slow metabolizers wait two hours for the same edible to peak.
Why Testing Transparency Matters
Products with third-party testing certificates give you predictable experiences. When you know exactly how much THC you're consuming, you can dial in your ideal amount.
Untested products might contain half to double their labeled potency. This variability makes every session a gamble.
Start Here If You're Trying Cannabis for the First Time Tonight
Choose your consumption method first. If you're going with edibles, start with 2 to 5mg of THC and set that 120-minute timer.
For smoking or vaping, take one small hit and wait 15 minutes. Have water ready and pick a comfortable environment where you feel safe.
Product Selection for Beginners
Look for products with clear labeling that shows exact THC content.
Our micro-dose gummies at 2mg each let you control your experience precisely.
Avoid products that don't specify THC amounts or seem unusually cheap. Quality control matters more for your first experience than any other factor.
Your Safety Setup
Have a trusted friend with you who knows you're trying cannabis for the first time. Prepare snacks, water, and something relaxing to watch or listen to.
Write down what you took and when. This simple record helps if you need to reference it later or share information with support staff.
When Greening Out Becomes a Pattern You Can't Break
If you're greening out regularly despite knowing better, it might be time to examine your relationship with cannabis. This isn't about judgment but finding an approach that works for you.
Some people need to stick permanently to micro amounts. Others benefit from scheduled breaks to reset their tolerance and relationship with THC.
Building Better Habits
Consider keeping a consumption journal, noting amounts, timing, and effects. Patterns often emerge that show your ideal THC range and timing.
Having non-THC options available helps too. CBD products provide relaxation without psychoactive effects when you want to unwind differently.
You Now Have Everything You Need Never to Green Out Again
The core insight is simple: control the rate at which THC enters your system, not just the total amount. Fast onset leads to problems, while slow, measured consumption keeps you safe.
Remember these three rules that will serve you in any situation.
Start with small THC amounts (2 to 5mg for edibles, one hit for inhalables), set your timer (120 minutes for edibles, 15 minutes for everything else), and wait completely before taking more.
Why These Rules Actually Stick
You now understand the science behind why these rules work. When you know that edibles convert differently in your liver and that THC stacks invisibly, the timer method makes perfect sense.
This isn't about fear or restriction. It's about having consistently positive experiences with cannabis by respecting its effects on your body.
Your Confidence Moving Forward
With this knowledge, you can enjoy cannabis without the fear of losing control. You have specific numbers, exact timing, and clear action steps for any situation.
Whether trying a new product, helping a friend, or just wanting a relaxing evening, you're equipped to handle it safely. The unpredictability that causes greening out is now under your control.
