Why a half-ounce is exactly 14 grams
A US ounce of cannabis is standardized at 28 grams (technically 28.3495 g, but rounded down to 28 industry-wide). Cut that in half and you get 14 grams — the half-ounce. The fraction-of-an-ounce naming convention (eighth, quarter, half, ounce) is a holdover from US imperial weight that became the de facto industry standard before legalization. Even in legal adult-use markets like New York, prices and menus default to those fractions because consumers ask for them by name. A half-ounce equals two quarters, four eighths, or 14 single grams.
How many joints, bowls, or pre-rolls in a half-ounce?
A 14-gram half-ounce rolls about 28 standard 0.5 g joints, or 47 thinner 0.3 g pinners. In a pipe, expect ~56 quarter-gram bowls. In pre-rolls, a half-ounce is equivalent to 28 half-gram pre-rolls or 14 full-gram pre-rolls. Dry-herb vape users will pull 70+ sessions at 0.2 g per bowl. For an average daily smoker, a half-ounce typically lasts three to five weeks. For multiple-session-per-day smokers, two to three weeks. For couples or roommates sharing, plan for two weeks max — at which point the per-person rate ends up similar to each person buying a quarter solo.
Storage becomes critical at the half-ounce level
Once you're storing 14+ grams, freshness becomes the limiting factor — not how much you smoke. The terpenes responsible for flavor and aroma are volatile and oxidize when exposed to air, light, or heat. To preserve a half-ounce: transfer it from the original bag into airtight glass jars (UV-resistant glass like Miron is the gold standard), add a Boveda or Integra Boost humidity pack at 62% RH, and store in a cool, dark cabinet. Avoid the fridge (too humid, condensation risk) and never the freezer (trichomes become brittle and snap off). With proper storage a half-ounce holds peak quality for three months and stays smokable for six.
Half-ounce pricing in New York
At licensed New York adult-use dispensaries, half-ounces typically run $120–$220 before tax. Value tier: $120–$150. Mid-shelf branded: $150–$190. Top-shelf craft flower: $190–$240. Per-gram, that's roughly $8.50–$17 — a notable step down from $10–$18/g for quarters and $14–$20/g for eighths. The half is where bulk-pricing economics start to bite: you're often paying ~25% less per gram vs buying four single eighths. Add New York's 13% adult-use cannabis excise tax plus standard state and local sales tax. Watch for dispensary 'half-ounce of the week' deals that stack with loyalty discounts.
When a half-ounce makes sense — and when it doesn't
A half-ounce is the right buy if: you smoke daily, you've already settled on a strain you love, you have proper storage, and you'll finish it within four to six weeks. A half-ounce is the wrong buy if: you're still strain-shopping (commit to one variety and you can't try others fresh), you're an occasional weekend user (you'll lose terpenes long before you smoke through it), or you don't have a sealed jar and humidity pack (open-bag storage destroys 14 grams fast). For most casual New York smokers, two quarters of different strains beats one half of a single strain — same total grams, twice the variety.
