Debate over raising cannabis lab lot size pits industry and labs before Assembly committee

Senate Bill 157, which would revise Nevada's cannabis testing rules by raising lot size limits and adopting a sliding scale of representative sampling, drew a lengthy and contested hearing before the Assembly Judiciary Committee.

Sponsor Senator Edgar Flores opened the presentation saying he was "here to urge you to puff puff pass Senate Bill 157" and described the bill as an attempt to modernize testing rules that date back to early implementation of Nevada's market. Proponents including Green Thumb Industries representatives, cultivators and the Nevada Cannabis Association told the committee SB 157 would move Nevada toward nationally accepted sampling standards, reduce testing costs for licensed operators and discourage consumers from buying untested products from the illicit market.

Proponents' arguments and technical support - Science and standards: David Valencourt, vice‑chair of ASTM International's cannabis committee and a testing consultant, urged regulators to "test smarter, not harder," advocating adoption of ASTM consensus sampling methods rather than a strict 5‑pound cap. He said other jurisdictions have raised lot sizes without safety issues. - Cost and market effects: University chemist Glenn Miller and industry witnesses said testing every 5‑pound lot drives up costs and can encourage diversion to unregulated sellers; Miller argued that subsampling techniques used in food safety can be applied to cannabis and that Washington state safely moved from a 5‑pound standard to a larger lot size.

Opposition from laboratories and public‑health concerns Testing laboratories and several independent lab owners testified in opposition, warning that contaminant distribution within flower is heterogeneous and that detection rates decline as the percentage of product sampled shrinks. Alec Garcia of 374 Labs said, "This bill ultimately comes down to 1 thing and that's patient and public safety." Opponents cited recall data and enforcement activity in other states and pointed to existing ASTM guidance that, they said, contains lower lot maxima for certain matrices (the testimony referenced ASTM D8334 and related guidance that defines a 15‑pound maximum for inflorescence in some provisions).

Technical specifics in the bill - Lot size: SB 157 would change the statutory lot size approach, with proponents proposing a sliding scale up to 50 pounds for certain cannabis flower lots (current Nevada rule cited in testimony is 5 pounds for flower). Proponents said representative sample counts would rise with lot size (examples given in testimony: 8 samples for lots under 10 pounds up to 19 samples for 40–50 pound lots) and that the bill incorporates ASTM sampling standards (witnesses cited ASTM D8334/D84236 practices). - Distinctions among product types: Cannabis Compliance Board staff explained Nevada already uses different lot sizes for different matrices (flower, trim, wet whole plant) and that the board has considered lot‑size changes in regulatory workshops through 2024 but did not adopt revisions.

Committee reaction and next steps: Members pressed proponents on differences between Nevada's cultivation (much indoor) and states with larger outdoor harvests and asked whether the Cannabis Compliance Board had been consulted; proponents said they had sought regulatory engagement and that the board declined to move the item into regulation. Several committee members asked for more data; the sponsor said he was open to negotiating on the numeric limit if stakeholders could provide research‑backed alternatives.

Ending: The hearing produced extensive oral testimony on both sides but no committee vote. Proponents argued larger lot sizes paired with rigorous sampling would lower costs and keep consumers in the regulated market; laboratory witnesses warned larger lots could permit contaminated product to reach consumers and cited recalls in other states.
