You’re standing at the counter, staring at a menu full of eighths and quarters, and all you really want to know is how many grams in an ounce — because the math between what you’re buying and what you’re actually consuming shouldn’t feel like a pop quiz you didn’t study for.

Let’s just get this out of the way: how many grams in an ounce? It’s 28.3495 grams, but in the cannabis world we round to 28 grams flat. Simple enough, right? The problem is that most DC medical cannabis patients stop there. They learn the conversion, toss it in their back pocket, and never connect the number to how they’re actually dosing. But here’s the thing — once you understand how those 28 grams break down across different strains, potencies, and consumption methods, you stop wasting money and start getting genuinely consistent relief.

That’s exactly the kind of conversation we have every day at Green Legacy’s Shaw dispensary. Our patient consultants don’t just weigh out your flower and send you on your way — they’ll walk you through strain-specific dosing so you actually know what a half-gram of a 27% THC indica is going to do versus a full gram of a mellow 15% hybrid. It’s the kind of guidance that turns a confusing menu into a personalized treatment plan. And honestly, that hands-on approach is what we’ve been about since day one.

I had a patient last spring — retired teacher, lived over near Dupont Circle — who’d been buying full ounces for months but had no idea she was consuming nearly three times her effective dose every session. She thought more flower meant better relief. We sat down, did the math together, dialed her back to about 0.3 grams per session with a higher-potency strain, and she texted me two weeks later saying she slept through the night for the first time in years. That’s what happens when you move past the basic conversion and start doing real, strain-specific calculations.
