So, you’re looking into an ounce of magic mushrooms. Maybe you saw the price tag and winced, or maybe you’re wondering why on earth someone would need that much fungus at once. Honestly, it's a lot. An ounce—28.35 grams—is the "bulk buy" of the psychedelic world. It's the Costco trip for the mind.
Most people start with an eighth (3.5 grams). That’s the standard. Moving up to a full ounce is a massive jump in both quantity and responsibility. We aren't just talking about a bag of dried stems; we’re talking about a significant supply that requires proper storage, a solid understanding of dosage, and a very real respect for the law and your own mental health.
Let's be real: the landscape is changing fast. In places like Oregon and Colorado, the legal frameworks are shifting, but for most of the world, having an ounce in your possession is a serious legal "yikes." It’s the difference between a slap on the wrist and a "possession with intent to distribute" charge.
Understanding the scale of an ounce of magic mushrooms
How big is an ounce? Physically, it’s about the size of a large bag of popcorn if the mushrooms are whole and dried. If they’re crushed or powdered, it’s much smaller, but usually, you’re looking at a sandwich-sized Ziploc bag stuffed to the gills.
Weight matters.
If you’re dealing with Psilocybe cubensis—the most common species—an ounce represents roughly eight "standard" doses of 3.5 grams. If you’re a microdoser, taking maybe 0.1 to 0.2 grams a few times a week, an ounce is basically a lifetime supply. Well, maybe not a lifetime, but certainly enough to last you a year or more.
Price is the big driver here. Just like anything else, buying in bulk is cheaper. Depending on where you are in the world—and let's assume we're talking about the gray markets in the US or Canada—an ounce can run anywhere from $150 to $300. In high-demand cities, it might be more. In places with decriminalization, prices have actually stabilized because the "risk premium" is lower for the people growing them.
Potency isn't a straight line
Here is what most people get wrong. They think all ounces are created equal. They aren't.
A 28-gram bag of Golden Teachers is a completely different beast than 28 grams of Penis Envy. The latter is notoriously more potent—sometimes two or three times as strong because of the higher concentration of psilocybin and psilocin. If you treat an ounce of a high-potency strain the same way you treat a "standard" strain, you’re going to have a very bad time.

Dr. Roland Griffiths and the team at Johns Hopkins have spent years studying psilocybin. Their research usually focuses on "weight-adjusted" doses of pure psilocybin, not raw mushroom weight. This is a crucial distinction. In a lab, they might give a participant 20mg or 30mg of psilocybin per 70kg of body weight. In your living room with an ounce of magic mushrooms, you have no idea if those 28 grams contain 200mg of psilocybin or 600mg.
It’s a guessing game. Always start low.
The storage problem nobody talks about
If you have an ounce, you have a storage problem.
Psilocybin is a relatively stable molecule, but it’s not invincible. It hates three things: heat, light, and oxygen. If you leave your ounce in a plastic baggie on top of your fridge, it will lose its potency within months. It’ll turn into expensive, dusty crackers that do nothing but make your stomach hurt.
The pros use glass. Mason jars are the gold standard.
- Throw in a silica desiccant pack (those "do not eat" packets you find in shoe boxes).
- Keep it in a dark, cool cupboard.
- Don't open it every day.
Every time you open the jar, you introduce fresh oxygen and moisture from the air. If you're planning to sit on an ounce for a long time, consider "fragmenting" your stash. Put three grams in a small jar for current use and keep the remaining 25 grams sealed away in a larger one.
Blue bruising is normal. It’s just oxidation. But if you see green or white fuzz that looks like it belongs on a loaf of bread? Toss it. Moldy mushrooms can make you incredibly sick, and no trip is worth a trip to the ER for lung or stomach infections.
Why an ounce of magic mushrooms is a legal "red zone"
Let’s talk about the elephant in the room. In the eyes of the law, weight is everything.

In many jurisdictions, the police don't care that you're just "stocking up" to save money. If you get caught with an ounce, the legal threshold often moves from "personal use" to "intent to sell." That is a massive difference in terms of jail time and fines.
Even in "decriminalized" cities like Seattle or D.C., decriminalization usually applies to "adult possession." However, the definition of what constitutes a "personal amount" is often left vague or capped at a lower weight than 28 grams. You have to check your local municipal codes. Don't rely on a Reddit thread from 2022.
The laws are shifting, sure. But they haven't shifted everywhere.
Dosage: Breaking down the 28 grams
You shouldn't ever eat an ounce at once. That sounds like a joke, but people do weird things. High-dose experiences (5 grams and up) are often called "Heroic Doses," a term coined by Terence McKenna. He advocated for five dried grams in silent darkness.
If you have an ounce, you have enough for five "Heroic Doses" and a little bit left over.
- Microdosing (0.1g - 0.3g): You’re looking at roughly 100 to 200 days of use.
- Low Dose (1g - 2g): Good for a social setting or a light "hike" dose. You get about 14 to 20 of these.
- Moderate Dose (3g - 3.5g): The classic experience. You get 8 of these in an ounce.
- High Dose (5g+): Deeply introspective, often ego-dissolving. You get about 5 of these.
Most seasoned users find that an ounce lasts them a year. They might trip deeply once every few months and microdose occasionally in between.
The physical reality of consumption
Eating 28 grams of dried mushrooms—even over the course of a year—is a lot of chitin. Chitin is the stuff mushroom cell walls are made of. Humans can't digest it well. This is why people get "the shakes" or "the bubbles" in their stomach.
If you have a whole ounce, you have the luxury of experimenting with better ways to eat them than just chewing on dry stems.

Lemon Tek is the big one. You grind the mushrooms into a powder and soak them in lemon juice for 15-20 minutes. The theory is that the citric acid begins the conversion of psilocybin into psilocin (the stuff that actually makes you trip), which usually happens in your stomach acid. It makes the come-up faster and the nausea less intense.
Then there's tea. Boil water, let it sit for a minute so it's not "rolling boil" hot (extreme heat can degrade psilocybin), and steep your ground-up mushrooms with some ginger and honey. Strain out the bits. Your stomach will thank you.
Nuance, set, and setting
Having an ounce of magic mushrooms gives you a sense of abundance, but it can also lead to "frequency creep." Just because you have it doesn't mean you should use it every weekend.
Tolerance builds instantly. If you take 3 grams on Friday, taking 3 grams on Saturday will do almost nothing. You’d need to double the dose to feel the same effects. It takes about two weeks for your brain’s 5-HT2A receptors to reset to baseline.
Respect the substance.
The most important thing isn't the weight of the bag, but the weight of your intention. Why are you doing this? If it's to escape, the mushrooms will often show you exactly what you're trying to run from. If it's to learn, they might just give you a lesson you weren't expecting.
Actionable Next Steps
If you’ve decided that an ounce is the right amount for you, follow these steps to ensure you’re doing it safely and effectively:
- Verify your source: If you didn't grow them yourself, ensure they are properly dried. They should be "cracker dry"—if they bend instead of snapping, they still have moisture and will rot.
- Invest in a scale: Do not eyeball it. A $15 milligram scale from any headshop or online retailer is the most important tool you can own. Guessing between 2 grams and 4 grams is the difference between a fun afternoon and a terrifying existential crisis.
- Control your environment: "Set and setting" isn't a suggestion; it's a rule. Be in a place where you feel safe, with people you trust, and no responsibilities for at least 12 hours.
- Prepare for the "Body Load": Have ginger tea, comfortable blankets, and a playlist ready. The physical sensation of coming up can be anxious; having your environment prepared reduces that friction.
- Legality check: Seriously. Look up the specific laws in your county and state. If you are in a place where it is strictly illegal, keep your stash at home. Never travel with an ounce.
Buying in bulk can save money, but it requires a level of maturity and organization that a single eighth does not. Treat your ounce like a medicine cabinet, not a snack bag. Keep it dark, keep it dry, and above all, keep it respected.
