You’re standing at the counter doing math on your phone, trying to figure out how many grams in an ounce before the budtender notices β€” and honestly, we’ve all been there.

Let’s settle this once and for all: how many grams in an ounce? It’s 28.3495 grams, but in the cannabis world we round to 28. That number matters more than you’d think, especially when you’re a DC medical cannabis patient trying to make your monthly budget actually work. Once you internalize that figure, every menu price starts making more sense. You can compare eighths, quarters, and halves without that weird mental fog. It’s the kind of basic math that saves you real money over the course of a year.

At Green Legacy, we walk patients through this stuff every single day β€” no judgment, ever. Whether you’re picking up a quarter in Shaw or scheduling a delivery to Dupont Circle, our team wants you to feel confident about what you’re buying and what you’re spending. We’ve found that patients who understand basic weed measurements tend to waste less product and get better results from their medicine. It sounds simple, but it’s genuinely one of the most empowering things you can learn as a newer patient.

I had a patient last year β€” retired teacher, lived over in Adams Morgan β€” who’d been buying pre-rolls exclusively for almost two years because she was intimidated by loose flower math. We spent maybe ten minutes walking her through grams, eighths, and ounces, and she literally texted us the next week saying she’d cut her monthly spend by a third. That’s not an unusual story, either. Once the measurement anxiety disappears, people start experimenting with different formats, dialing in their doses, and actually enjoying the process.

6 Tips Using How Many Grams in an Ounce

01
🌿

Memorize the Breakdown Chart

An eighth is 3.5g, a quarter is 7g, a half is 14g, and a full ounce is 28g. Write it on a sticky note if you have to. Once these numbers are second nature, you’ll never feel lost reading a dispensary menu again.

Track Your Weekly Consumption

Grab a small kitchen scale (they’re like twelve bucks) and weigh out what you actually use in a week. Most DC patients we talk to are surprised β€” they’re either using way more or way less than they assumed. Hard data beats gut feeling every time.

03
πŸ§ͺ

Compare Price Per Gram Always

Don’t just look at the sticker price β€” divide it by the number of grams. That $55 eighth might look cheaper than the $90 quarter, but do the math: you’re paying $15.71/g versus $12.86/g. Buying in slightly larger increments almost always saves money over time.

Rotate Strains to Prevent Tolerance

Tolerance buildup is a budget killer. If you’re burning through flower faster just to feel the same effects, it’s time to switch things up. Keep two or three strains in rotation and you’ll stretch each gram further β€” your endocannabinoid system will thank you.

Use Your Patient Allotment Wisely

DC’s medical cannabis program sets monthly allotments for a reason. Plan your purchases around your actual usage data (see tip two) instead of impulse-buying. Patients who plan ahead rarely hit their limit and almost always spend less.

Your Questions About How Many Grams in an Ounce β€” Answered

So really, how many grams in an ounce of cannabis?

Exactly 28.3495 grams, but the cannabis industry rounds to 28 grams. Every licensed dispensary in DC uses this standard, so you can shop with confidence. If you’re ever unsure about what you’re getting, just ask β€” or check out our FAQ page for more breakdowns.

What’s the most cost-effective amount of flower to buy at a DC dispensary?

Generally, the larger the quantity, the lower the price per gram. Buying a quarter (7g) or a half ounce (14g) usually saves you 10-20% compared to buying individual eighths. That said, if you’re new, start with a smaller amount to make sure you like the strain before committing to more.

How long does an ounce of medical cannabis typically last?

It depends entirely on your consumption method and frequency. For a moderate daily user, a full ounce might last four to six weeks. Patients who primarily use vaporizers (which are more efficient) can stretch it even longer. Tracking your weekly usage is the best way to find your personal number.

Can I get medical cannabis delivered in DC?

Absolutely. DC’s medical cannabis program allows licensed dispensaries to deliver directly to registered patients. Green Legacy offers convenient delivery scheduling across DC neighborhoods β€” from Capitol Hill to Tenleytown. You’ll need your valid DC medical cannabis card and a government-issued ID.

How do I register for DC’s medical cannabis program?

Start with DC Health’s Medical Cannabis Program page β€” they outline the full process, including finding a recommending physician. Once you’re registered and have your card, you can shop at any licensed dispensary in the District. The whole process has gotten much smoother over the past couple of years.
