Why an ounce is 28 grams (not 28.35)
A US ounce technically weighs 28.3495 grams, but the cannabis industry rounds down to 28 g for clean math. Every traditional flower weight derives from that 28-gram base: 1 ounce = 28 g, 1 half = 14 g, 1 quarter = 7 g, 1 eighth = 3.5 g, 1 gram = 1 g. The naming convention predates legal markets — when cannabis was sold informally, US imperial weights were the universal measurement, and the convention stuck even as scales went digital and gram-precise. New York adult-use law uses the metric '3 ounces' as the in-public possession cap, which converts to 84 grams — about 24 eighths.
How many joints, bowls, or pre-rolls in an ounce?
A 28-gram ounce rolls about 56 standard 0.5 g joints, or up to 93 thinner pinners. In a pipe, expect ~112 quarter-gram bowls. In pre-rolls, an ounce is equivalent to 56 half-gram pre-rolls or 28 full-gram pre-rolls. Dry-herb vape users will get 140+ sessions at 0.2 g per bowl. For a typical daily smoker, an ounce lasts six to ten weeks. For heavy multi-session daily smokers, three to five weeks. For couples or roommates, plan for three to four weeks. Most casual NY consumers will never need a full ounce — quarter or half is the right size.
Ounce pricing in New York
Licensed New York dispensary ounces typically run $200–$400 before tax. Value tier: $200–$260. Mid-shelf branded: $260–$340. Top-shelf craft flower: $340–$450. Per-gram, that's roughly $7–$16 — the lowest per-gram price of any flower weight. Compared to buying eight separate eighths, you'll save 25–35% per gram by buying the ounce up front. Add New York's 13% adult-use cannabis excise tax plus standard state and local sales tax. Watch for monthly 'ounce special' promotions — many NY dispensaries run loss-leader ounce prices to drive bulk traffic.
New York legal possession limits
Under New York's Marijuana Regulation and Taxation Act (MRTA), adults 21+ may legally possess up to 3 ounces of cannabis flower (and up to 24 grams of cannabis concentrate) in public. At home, the storage limit is 5 pounds of cannabis flower. You can purchase up to 3 ounces in a single transaction at a licensed adult-use dispensary. Driving with cannabis is legal as long as it's stored away from the driver's reach — glove compartment or trunk. It's illegal to consume cannabis while operating a vehicle or on federal property. Always carry your government-issued 21+ ID when traveling with any quantity.
Storage rules for an ounce
An ounce will last most users six to ten weeks — long enough that storage becomes the difference between great flower at week ten and stale flower at week three. Split the ounce across multiple smaller airtight glass jars (don't open a single 28 g jar repeatedly; each open cycle drops humidity and oxidizes terpenes). Use Boveda or Integra Boost humidity packs at 62% RH in each jar. Store jars in a cool, dark cabinet — not the fridge, never the freezer. UV-resistant glass like Miron extends shelf life further. Properly stored, an ounce of NY craft flower holds peak quality for three to four months.
