How much cannabis can you buy in Nevada?

A Nevada retail store may not sell more than 2.5 ounces of usable cannabis, or more than one quarter of an ounce of concentrated cannabis, in any one transaction. The Cannabis Compliance Board publishes 2.5 ounces of usable cannabis as the equivalent to one quarter ounce of concentrated cannabis at 7,087 milligrams of THC, and its exchange chart trades flower weight against those milligrams. The figures took effect January 1, 2024.

Usable cannabis, flower only

2.5 ounces (70.88 g)

Two figures govern a Nevada sale, and they work as equivalents

Nevada writes the retail limit as two figures. Senate Bill 277 states that a cannabis sales facility shall not sell to a person, in any one transaction, more than 2.5 ounces of usable cannabis or more than one-fourth of an ounce of concentrated cannabis. Concentrated cannabis, in the Cannabis Compliance Board's wording, is the separated resin, whether crude or purified, obtained from cannabis. The two figures are not a total you add together. The board states that retail stores are not permitted to sell more than 2.5 ounces of usable cannabis, the equivalent to one-fourth ounce of concentrated cannabis at 7,087 milligrams of THC, or a combination of usable and concentrated cannabis that exceeds the legal limit. Conversions matter at the counter, because packaging is labeled in grams and milligrams while the limit is written in ounces. The board's chart gives 2.5 ounces as 70.88 grams and one quarter of an ounce as 7.09 grams.

Usable cannabis, flower only: 2.5 ounces (70.88 g)
Concentrated cannabis, equivalent not additive: 1/4 ounce (7.09 g)
THC in other products, at zero flower: 7,087 mg
Effective date: January 1, 2024 (Senate Bill 277)
Minimum age: 21

The transaction cap and the possession ceiling carry the same numbers

Senate Bill 277 moved both numbers at the same time. Section 4 set the retail transaction cap. Section 14 amended NRS 678D.200, which now sets the possession figures at two and one-half ounces of usable cannabis in paragraph (d)(1) and one-fourth of an ounce of concentrated cannabis in paragraph (d)(2), measured at any one time rather than per receipt. The bracketed text in the bill shows what those figures replaced: one ounce of usable cannabis and one-eighth of an ounce of concentrated cannabis. Sections 1 to 15.5 of the bill became effective on January 1, 2024 for all purposes other than preparatory administrative work. The Cannabis Compliance Board states the possession maximum as two and one-half ounces of usable cannabis other than concentrated cannabis, one-quarter ounce of concentrated cannabis or cannabis products containing not more than 7,087 milligrams of THC, or a combination of usable and concentrated cannabis not to exceed the legal limit. Because possession is measured at any one time, splitting a large order across two sales does not raise the amount you may lawfully hold afterwards.

Transaction cap: Senate Bill 277 (2023), Section 4

The state exchange chart trades flower weight against THC milligrams

Buying flower and other products in the same visit is where the arithmetic gets fiddly, so the Cannabis Compliance Board publishes an exchange chart. The left side lists a flower weight and the right side lists how much THC in other products is within limits at that weight. The more flower in the basket, the fewer milligrams remain. At zero flower the figure is 7,087 milligrams. At one eighth of an ounce, 3.54 grams, it is 6,733 milligrams. At one quarter of an ounce, 7.09 grams, it is 6,379 milligrams. At half an ounce, 14.18 grams, it is 5,670 milligrams. At one ounce, 28.35 grams, it is 4,255 milligrams. At one and a half ounces, 42.53 grams, it is 2,839 milligrams. At two ounces, 56.70 grams, it is 1,423 milligrams. At the full two and a half ounces, 70.88 grams, the allowance for THC in other products is zero. Total the milligrams printed on each package label before you reach the register and the chart stops being a surprise.

0 oz flower: 7,087 mg THC in other products
1/8 oz (3.54 g) flower: 6,733 mg
1/4 oz (7.09 g) flower: 6,379 mg
1/2 oz (14.18 g) flower: 5,670 mg
1 oz (28.35 g) flower: 4,255 mg
1 1/2 oz (42.53 g) flower: 2,839 mg
2 oz (56.70 g) flower: 1,423 mg
2 1/2 oz (70.88 g) flower: 0 mg

Age and identification at a licensed Nevada store

The Cannabis Compliance Board states that a customer must provide a valid government issued photo identification to prove that they are 21 years of age or older. NRS 678D.500 works from the other direction, providing that regulations the board adopts must not require a consumer to give an adult-use cannabis retail store personally identifiable information other than government-issued identification to determine the age of the consumer. When the figures changed, the board recommended that sales facilities update their point of sale systems so that transactions do not exceed the new limits, and said sales facilities should update their required signage to reflect the current limits by January 30, 2024. Keep out of reach of children. For use only by adults 21 years of age and older.

Minimum age: 21
Required at purchase: Valid government issued photo identification
Point of sale systems: Board recommended an update to the new limits
Signage update date: January 30, 2024
Transaction cap: 2.5 oz usable or 1/4 oz concentrated

Do the conversions before you queue

Two habits keep a visit short. First, convert to grams and milligrams before you shop, because labels use metric while the limit is written in ounces. Second, count edibles, cartridges and concentrates as one pooled THC figure rather than as separate categories, since the chart totals THC in other products together. Nevada law helps here. NRS 678D.420 requires an adult-use edible cannabis product or a cannabis-infused product to be labeled in a manner which indicates the number of servings of THC in the product, measured in servings of a maximum of 10 milligrams per serving. Keep the packaging rules separate from the transaction rules, because the same statute caps a single package of concentrated cannabis at 3,500 milligrams of THC, which is a different number from the 7,087 milligram transaction figure. If you are not sure how a basket totals against the limit, ask before you pay. Product formats and quantities currently on the shelf appear in the live ordering system, not on this page.

Label requirement, edibles and infused products: Servings of THC, maximum 10 mg per serving (NRS 678D.420(1))
Single package, concentrated cannabis: Not more than 3,500 mg THC (NRS 678D.420(2)(b))
Single package, usable cannabis: Not more than 2.5 ounces (NRS 678D.420(2)(a))

Questions

How much flower can I buy in Nevada in one transaction?

Up to 2.5 ounces of usable cannabis, which the Cannabis Compliance Board's chart gives as 70.88 grams. Section 4 of Senate Bill 277 set that cap, effective January 1, 2024, replacing a one ounce limit. The same figure appears in NRS 678D.200 as the amount an adult 21 or older may possess at any one time.

Can I buy 2.5 ounces of flower and a quarter ounce of concentrate together?

No. The Cannabis Compliance Board publishes 2.5 ounces of usable cannabis as the equivalent to one-fourth ounce of concentrated cannabis at 7,087 milligrams of THC, and does not permit a combination of usable and concentrated cannabis that exceeds the legal limit. On the board's exchange chart, the allowance for THC in other products falls to zero once the basket reaches 2.5 ounces of flower.

Is the Nevada limit per transaction or per day?

Neither figure is published as a daily allowance. Section 4 of Senate Bill 277 caps a single transaction, and NRS 678D.200 measures possession at any one time, so splitting an order across two sales does not raise the amount you may lawfully hold.

What identification do I need at a Nevada dispensary?

A valid government issued photo identification proving you are 21 years of age or older, in the Cannabis Compliance Board's wording. NRS 678D.500 also provides that board regulations must not require a consumer to give an adult-use cannabis retail store personally identifiable information other than government-issued identification to determine the age of the consumer.

When did Nevada raise its purchase limit?

January 1, 2024. Senate Bill 277 raised the usable cannabis figure from one ounce to two and one-half ounces, and the concentrated cannabis figure from one-eighth of an ounce to one-fourth of an ounce. The board asked sales facilities to update their required signage to the current limits by January 30, 2024.
