Recreational cannabis (marijuana-derived Delta-9 THC)
As of March 2026, 24 states plus Washington D.C. have legalized recreational cannabis for adults 21 and older, covering marijuana-derived products sold through licensed dispensaries — Delta-9 THC flower, edibles, concentrates, and vapes. This is entirely distinct from the hemp-derived cannabinoid market. No new state achieved recreational legalization in 2025. Ohio (2023), Minnesota (2023), and Delaware (2023) are still completing retail infrastructure. Home cultivation is permitted in 20 of the 24 recreational states — Delaware, Illinois, New Jersey, and Washington are the four exceptions, though all have active bills advancing in 2026.
Medical cannabis
Medical cannabis is legal in 40 states, three territories, and D.C. Nebraska became the most recent addition when voters passed Initiative 437 in November 2024. Kentucky's program launched dispensary operations in 2025. The only states with no cannabis program of any kind are Idaho, Kansas, and Wyoming. Programs vary dramatically — Oklahoma operates one of the most open medical markets nationally, while Texas restricts access to low-THC cannabis for a narrow list of qualifying conditions under the Compassionate Use Program.
Hemp-derived THCa (the Farm Bill market)
Critical distinction: Hemp-derived THCa products sold in smoke shops, vape stores, and online are legally separate from cannabis dispensary products. The 2018 Farm Bill's Delta-9-only cap left THCa unregulated, creating a large market that is now being aggressively dismantled. California banned all hemp-derived intoxicating cannabinoids (AB 8, 2024, upheld in court). Maryland banned intoxicating hemp outside licensed dispensaries (upheld by Appellate Court Sep 2025). Alabama (HB445), Arkansas (Act 629), Louisiana (HB 952), and Georgia (SB 494) enacted explicit bans. Federally, Section 781 of P.L. 119-37 (signed Nov 2025) redefines hemp to include total THC, effectively banning most hemp-derived THCa products as of November 12, 2026.
Hemp and CBD
Hemp was federally legalized under the 2018 Farm Bill, enabling a $28 billion industry. All 50 states allow hemp cultivation. However, Section 781 (Nov 2025) replaces the Delta-9-only threshold with a total THC standard and caps finished products at 0.4mg total THC per container — a level that would affect not only THCa products but also many standard CBD wellness products currently on shelves. The Farm Bill reauthorization (draft filed Feb 2026) may reverse or replace these changes. Rep. Nancy Mace's H.R. 6209 would repeal Section 781 entirely.
Home cultivation
Home grow rights exist in approximately 20 recreational states plus D.C., and in some medical-only states for registered patients. Plant limits range from 2 per household in Maryland to 12 in Michigan. Most states require plants to be secured and out of public view. Nevada permits home grows only for residents living 25+ miles from a dispensary — effectively excluding most Las Vegas-area residents. The four recreational states with no home grow — Delaware, Illinois, New Jersey, and Washington — all have active bills in 2026.
Federal status
Cannabis remains Schedule I federally under the Controlled Substances Act. On December 18, 2025, President Trump signed Executive Order 14370 directing the DEA and HHS to expeditiously reclassify cannabis to Schedule III. This would lift Section 280E tax penalties, open banking access, and ease research restrictions — but would not legalize cannabis federally. As of March 2026, the DEA rulemaking is ongoing with no final action taken.

Critical federal
Section 781 — Federal hemp/THCa ban effective November 12, 2026
Signed Nov 2025 (P.L. 119-37). Redefines federal hemp to include total THC (including THCa). Caps finished hemp products at 0.4mg total THC per container. Most THCa flower, Delta-8, and many CBD products become federally illegal November 12, 2026.

Cannabis rescheduling — Schedule I to Schedule III
Trump's Executive Order 14370 (Dec 2025) directed expedited rescheduling. Would lift Section 280E tax penalties, open banking, and ease research. DEA rulemaking ongoing — no final action as of March 2026.
Rulemaking in progress
Farm Bill reauthorization (2026)
House Agriculture Committee Chairman Thompson filed an 802-page draft in February 2026. Will determine whether Section 781 is reversed, expanded, or replaced with a permanent regulatory framework for hemp and cannabinoids.

State legislature sourcing: For pending legislation specifically, the monthly AI research pass is instructed to verify bill status directly against official state legislature websites (e.g. legislature.hawaii.gov for Hawaii SB 3275, legis.virginia.gov for Virginia retail bills) before updating any state's pending field. This ensures pending legislation summaries reflect actual current bill status rather than news coverage of bills.
