Executive Summary
Maryland Senate Bill 215 addresses two distinct cannabis policy needs: extending medical cannabis delivery authorization and creating the state's first on-site consumption licensing framework. While the medical delivery extension is administrative housekeeping (maintaining status quo for one year), the on-site consumption provision represents Maryland's recognition of a fundamental challenge facing all legal cannabis markets: where can consumers legally use the product they legally purchased?
CBDT Assessment: SB 215 is a modest positive for Maryland's legal market. By creating licensed consumption venues—particularly targeting tourists, renters, and consumers without private consumption spaces—the bill addresses the convenience variable (1× weight) and tourism appeal. Projected market share improvement: +1 to +2 percentage points.
However, SB 215 does not address Maryland's core challenges: insufficient dispensary density (1.6 per 100,000 versus optimal 2.5-3.5), lack of adult-use delivery authorization, or the pending July 2025 tax increase from 9% to 12%. The bill solves a real problem for a specific consumer segment but cannot overcome price competitiveness gaps or access barriers affecting Maryland's broader 60-68% legal market share.
The honest assessment: SB 215 is smart incremental policy that modernizes Maryland's cannabis framework. It's necessary for market maturation—but insufficient for optimization. Maryland needs consumption venues AND delivery expansion AND tax rate maintenance to capture its deserved 75-82% legal market share.
What SB 215 Does
Maryland's SB 215 contains two distinct provisions with vastly different implications for the legal cannabis market.
Provision 1: Medical Cannabis Delivery Extension (Administrative)
Current law: Medical cannabis delivery authorization expires July 1, 2025.
SB 215 change: Extends medical delivery authority to July 1, 2026 (one additional year).
Why this matters: Maryland authorized medical cannabis delivery as a temporary pandemic-era accommodation. The program has proven successful, serving mobility-impaired patients and rural medical consumers. Without SB 215's extension, 93,948 registered medical patients would lose delivery access on July 1, 2025.
CBDT impact: Minimal—this provision maintains status quo rather than expanding access. Medical delivery already exists; SB 215 prevents its elimination.
Policy context: This provision buys time for broader delivery policy debate. Maryland prohibits adult-use delivery (a significant access gap affecting the state's 60-68% legal market share), while medical delivery operates successfully with no public safety incidents. The real question is when Maryland will authorize adult-use delivery statewide—not whether medical delivery should continue.
Provision 2: On-Site Consumption Licensing (Transformative)
Current law: No legal on-site cannabis consumption. Consumers can purchase cannabis from 102 licensed dispensaries but have no legal public consumption venue.
SB 215 creates: Licensed "cannabis consumption establishments" modeled on Amsterdam's coffee shop framework.
The Consumption Establishment Framework
Licensing structure:
- New license class: On-site consumption establishment
- Social equity applicants receive priority consideration during initial application windows
- Municipal control: Counties and municipalities may establish operating hours, zoning requirements, and can limit or prohibit operation entirely
Product restrictions:
- No indoor smoking permitted—only vaping, edibles, and cannabinoid beverages
- 5mg THC per serving maximum for beverages consumed on-site
- Must be purchased on-site—no BYOC (bring your own cannabis)
- All products must be single-serving, lab-tested, properly labeled per Maryland Cannabis Administration standards
Operational requirements:
- Age 21+ only (government ID verification at entrance)
- ABCA §36–203.1 packaging and labeling compliance
- Metrc seed-to-sale tracking integration
- Same testing standards as dispensary products
- No consumption visible from public areas
- Cannot be located within 1,000 feet of schools, playgrounds, or youth centers (standard buffer)
Municipal opt-out authority:
- Jurisdictions can prohibit consumption establishments through local ordinance
- Can restrict consumption methods (e.g., prohibit vaping, allow only edibles)
- Can establish operating hours more restrictive than state default (6 AM - midnight)
- Cannot ban outright if county permits (state preemption at county level)
The Problem: Legal Purchase, Illegal Consumption
Maryland's current cannabis policy creates an absurd situation: adults 21+ can legally purchase cannabis from licensed dispensaries but have no legal public consumption venue. This affects three consumer segments particularly hard:
1. Tourists and Visitors
The dilemma: Out-of-state tourists can purchase cannabis legally but cannot consume it legally anywhere in Maryland.
- Hotel rooms: Prohibited by hotel policy (and illegal under current law)
- Rental cars: Prohibited by federal law (vehicles crossing state lines)
- Public parks: Prohibited by state law
- Rental properties: Owner discretion (most prohibit)
Result: Tourists either:
- Consume illegally in hotel rooms (risking eviction, fines)
- Don't purchase at all (lost legal market sales)
- Purchase from illicit delivery services that don't care about consumption location
Market impact: Maryland's proximity to Washington DC, Philadelphia, and New York creates substantial tourist demand. Without consumption venues, Maryland loses cannabis tourism revenue to neighboring states with better infrastructure.
2. Renters Without Consumption Rights
The challenge: Maryland's 36.8% renter households often face lease clauses prohibiting cannabis consumption on premises.
Even though cannabis is legal, landlords retain right to prohibit use in rental units (similar to tobacco smoking restrictions). This creates a class of legal cannabis consumers with no legal consumption location.
Result: Renters either:
- Consume illegally in their apartments (risking eviction)
- Consume in cars or public spaces (risking arrest)
- Don't purchase legal cannabis (illicit markets offer delivery to home)
Equity concern: Renters disproportionately lower-income and minority households. Consumption restrictions create de facto class/race-based access barriers to legal cannabis.
3. Medical Patients Needing Social Spaces
Medical context: Cannabis reduces social isolation for patients with chronic conditions, PTSD, or terminal illness. Many medical patients benefit from communal consumption spaces where they can socialize with others facing similar challenges.
Current problem: Medical patients must consume at home (isolating) or violate public consumption laws.
SB 215 solution: Consumption establishments could host medical patient support groups, educational sessions, and social gatherings in legally compliant setting.
CBDT Framework Analysis
The Consumer-Driven Black Market Displacement (CBDT) Framework identifies five levers determining legal market capture. SB 215 directly strengthens one—Convenience—while creating modest improvements in tourism appeal.
Lever 1: Price Gap (g) — NO EFFECT
Weight: 4× (highest impact)
SB 215 does not affect cannabis pricing. The bill neither reduces Maryland's 9% sales tax (increasing to 12% July 2025) nor addresses the 280E federal tax burden forcing Maryland dispensaries to charge premium prices.
Maryland pricing context:
- Legal retail: $8.40/gram flower, $27-28 average item price
- Illicit market: $6-8/gram flower, $18-22 equivalent items
- Legal premium: 20-40% above illicit
SB 215 impact: Consumption venues must charge retail prices (plus potential service fees). Price-sensitive consumers still face incentive to buy illicit.
CBDT impact: 0 percentage points
Lever 2: Access Density (D) — INDIRECT MINOR POSITIVE
Weight: 1×
SB 215 does not increase dispensary count (Maryland has 102 licensed dispensaries, optimal would be 160-220). However, consumption establishments function as de facto access points for tourists and consumers without private consumption spaces.
Geographic distribution prediction:
- Urban concentration: Baltimore City (8-12 lounges), Silver Spring/Bethesda (5-8), Annapolis (3-5)
- Tourist areas: Ocean City (2-4), Frederick (2-3), College Park (2-3)
- Rural areas: Minimal (<2 per county, many counties zero)
Access improvement: For tourists in Baltimore or Ocean City, consumption lounges improve effective access by creating viable consumption location near dispensaries. This is particularly valuable for weekend visitors who might not purchase without consumption venue.
CBDT impact: +0.2 to +0.4 percentage points (indirect access improvement for specific consumer segments)
Lever 3: Safety/Quality (S) — MINOR POSITIVE
Weight: 1.2×
Testing requirements: SB 215 mandates that all products sold at consumption establishments meet Maryland Cannabis Administration testing standards and ATCC packaging/labeling requirements. This includes:
- Cannabinoid potency verification
- Pesticide screening
- Heavy metals testing
- Microbial contaminants screening
Dosing education: Consumption establishments can provide on-site education about appropriate dosing, particularly for cannabinoid beverages (5mg THC per serving limit reduces overconsumption risk).
Comparison to illicit: Consumption lounges create controlled environment where new consumers can learn responsible use from staff—versus illicit dealers who provide no guidance.
CBDT impact: +0.1 to +0.2 percentage points (modest safety perception improvement)
Lever 4: Convenience (F) — MODERATE POSITIVE
Weight: 1×
This is SB 215's primary contribution. The bill addresses the "where can I consume?" problem that reduces legal purchase convenience for three segments:
Tourist convenience:
- Current: Purchase legally, consume nowhere legally → Purchase from illicit delivery instead
- With SB 215: Purchase legally, consume at licensed lounge → Legal transaction completes
Estimated tourist market: Maryland cannabis sales to non-residents estimated at 8-12% of total ($91-144M of $1.2B annual market). Without consumption venues, significant portion of tourist demand goes illicit.
Renter convenience:
- Current: Purchase legally, risk eviction by consuming at home → Don't purchase or buy illicit
- With SB 215: Purchase legally, consume at lounge → Legal option viable
Social consumption preference:
- Some consumers prefer social cannabis use (similar to bars vs. drinking alone at home)
- Lounges enable legal social consumption, matching preference
Hours of operation: SB 215 establishes state default of 6 AM - midnight, with municipal authority to restrict further. This matches dispensary hours and provides adequate access windows.
CBDT impact: +0.6 to +1.0 percentage points (convenience improvement for tourists, renters, social consumers)
Lever 5: Enforcement (E) — NO EFFECT
Weight: 0.6×
SB 215 does not change enforcement priorities or resources. Maryland's enforcement remains focused on large-scale illegal cultivation, interstate trafficking, and unlicensed retail operations.
Public consumption enforcement: SB 215 provides legal alternative to public consumption, which may modestly reduce enforcement incidents. However, illicit supply-side enforcement unchanged.
CBDT impact: 0 percentage points
Fragmentation Modifier (F_frag) — MINIMAL
Weight: -0.8×
Municipal opt-out risk: SB 215 allows counties and municipalities to prohibit consumption establishments through local ordinance. This creates potential fragmentation similar to California's retail ban problem (61% of jurisdictions prohibit dispensaries).
Maryland advantage: Unlike California's strong home rule tradition, Maryland has demonstrated willingness to use state preemption. The state's cannabis law already limits municipal authority over dispensary locations (1,000-foot buffers allowed, outright bans not permitted).
Prediction: Expect 10-20% of Maryland jurisdictions to prohibit consumption lounges initially (conservative rural counties, some suburbs). This is manageable fragmentation—not California-level disaster.
CBDT impact: -0.1 to -0.2 percentage points (modest fragmentation penalty)
CBDT Score Summary
| Lever | Weight | SB 215 Impact | Contribution |
|---|---|---|---|
| Price Gap (g) | 4× | None | 0 pp |
| Access Density (D) | 1× | Indirect minor positive | +0.2 to +0.4 pp |
| Safety/Quality (S) | 1.2× | Minor positive | +0.1 to +0.2 pp |
| Convenience (F) | 1× | Moderate positive | +0.6 to +1.0 pp |
| Enforcement (E) | 0.6× | None | 0 pp |
| Fragmentation (F_frag) | -0.8× | Minor negative | -0.1 to -0.2 pp |
| Net Effect | — | — | +1 to +2 pp |
Maryland legal market share:
- Current: 60-68%
- Post-SB 215 (if passed): 61-70%
- With SB 215 + adult-use delivery + maintained 9% tax: 67-75%
- With SB 215 + delivery + federal reform: 76-83%
Comparison to Other States: Lessons from Social Consumption Pioneers
Maryland is not the first state to authorize on-site cannabis consumption. Analyzing existing programs reveals implementation challenges and success factors.
Colorado: The Pioneer (2013 Amsterdam Model, Expanded 2019)
Framework: Colorado's Proposition 300 authorized BYOC (bring your own cannabis) consumption lounges in 2016, then expanded to retail sale venues in 2019.
Current status:
- ~10 operational consumption lounges statewide (as of 2025)
- Concentrated in Denver metro (7-8 venues)
- Limited rural penetration
Lessons learned:
- Municipal opt-outs killed expansion: Most Colorado jurisdictions prohibit consumption lounges
- Business model challenges: Lounges struggle with profitability (can't serve alcohol, limited revenue streams)
- Tourist appeal strong: Denver lounges popular with visitors, less so with residents
CBDT impact in Colorado: +0.5 to +1.0 percentage points (modest improvement, mainly tourist segment)
Nevada: Tourism-Focused Success (2017)
Framework: Nevada authorized consumption lounges targeting Las Vegas Strip tourists.
Current status:
- 6-8 operational lounges in Clark County (Las Vegas area)
- Zero in rural Nevada
- Premium pricing model ($50-80 cover charges at high-end venues)
Lessons learned:
- Works for tourist markets: Las Vegas lounges successfully capture tourist demand
- Premium positioning viable: High-end venues can charge substantial premiums
- Local residents use less: Lounges primarily tourist-serving infrastructure
CBDT impact in Nevada: +1.5 to +2.0 percentage points (strong impact due to tourist concentration)
California: Fragmentation Disaster (2018)
Framework: California authorized both retail and BYOC consumption lounges.
Current status:
- ~15-20 operational lounges statewide (for 40M residents, 1,000+ dispensaries)
- Most jurisdictions ban consumption lounges (same fragmentation as retail)
- San Francisco and Oakland primary markets
Lessons learned:
- Local bans kill initiative: 61% of California jurisdictions ban retail AND consumption venues
- Without retail density, lounges struggle: Few dispensaries = few nearby lounges = poor consumer experience
- California's dysfunction affects everything: General regulatory chaos extends to consumption licensing
CBDT impact in California: +0.2 to +0.4 percentage points (minimal due to fragmentation)
New York: Emerging Market (2023-2024)
Framework: New York authorized on-site consumption as part of 2021 legalization, implemented slowly 2023-2024.
Current status:
- 5-10 operational lounges (as of late 2025)
- Concentrated in NYC
- Still rolling out amid New York's chaotic licensing process
Too early for assessment: New York's broader market dysfunction (30% legal market share, regulatory chaos) makes it difficult to isolate consumption lounge impact.
Massachusetts: Cautious Approach (2019, Limited Implementation)
Framework: Massachusetts authorized consumption cafes in 2019 but implementation has been extremely limited.
Current status:
- 2-3 operational venues statewide
- Strict local approval requirements
- Most municipalities have not acted
CBDT impact in Massachusetts: <0.5 percentage points (too limited for meaningful impact)
Maryland's Strategic Position: Learning from Others' Mistakes
Maryland's SB 215 incorporates lessons from other states while creating Maryland-specific implementation challenges.
What Maryland Gets Right
1. Social equity priority:
- Consumption licenses prioritized for social equity applicants during initial windows
- This addresses Colorado's mistake (early lounges primarily white-owned)
- Prevents gentrification of cannabis social spaces
2. Product restrictions reduce controversy:
- No indoor smoking (reduces secondhand smoke concerns)
- 5mg THC beverage servings (prevents overconsumption)
- On-site purchase requirement (prevents grey market product entry)
- These restrictions make municipal approval more likely
3. Municipal control with state framework:
- Maryland balances state authority with local control
- Not California-style fragmentation (61% bans) but not forced implementation either
- Reasonable middle ground
What Could Go Wrong
1. Business model viability:
- Colorado lounges struggle with profitability
- Can't serve alcohol (reduces revenue)
- Cover charges alienate price-sensitive consumers
- High-end premium model works in Vegas, not necessarily Maryland suburbs
2. Geographic concentration:
- Lounges will concentrate in Baltimore, DC suburbs, Ocean City
- Rural Maryland sees little benefit
- Creates two-tier system: Urban areas with consumption venues, rural areas without
3. Municipal opt-outs:
- Conservative counties will prohibit lounges
- Some suburbs ban due to NIMBY concerns
- Result: Spotty availability reduces overall impact
4. Competition from home consumption:
- Most Maryland residents can consume at home legally
- Lounges serve specific niches (tourists, renters, social users)
- Market may be smaller than hoped
Implementation Challenges
If SB 215 passes in 2026, Maryland will face several operational challenges during rollout:
Challenge 1: Licensing Timeline
Estimated timeline:
- October 2025: Bill becomes effective (if passed in 2026 session)
- Q4 2025 - Q1 2026: Maryland Cannabis Administration drafts regulations
- Q2 2026: Social equity application window opens
- Q3 2026: General application window opens
- Q4 2026 - Q1 2027: First consumption lounges become operational
Challenge: 12-18 month delay between bill passage and first lounges opening. This is faster than California (2-3 years) but slower than Nevada (6-9 months).
Challenge 2: Real Estate and Zoning
Zoning requirements:
- 1,000-foot buffer from schools, playgrounds, youth centers (standard)
- Commercial zoning typically required
- Parking requirements vary by jurisdiction
- ADA accessibility mandates
Real estate availability:
- Urban areas: Limited affordable commercial space
- Suburban areas: NIMBY opposition to cannabis venues
- Tourist areas: High rent makes business model challenging
Result: First lounges will be in premium locations (downtown Baltimore, Bethesda, Ocean City boardwalk area) with high operating costs.
Challenge 3: Ventilation and Air Quality
Technical requirement: Even with no indoor smoking, vaping produces visible vapor that must be managed through HVAC systems.
Cost: Commercial ventilation systems cost $15,000-40,000 for typical 2,000 sq ft venue.
Regulatory compliance: ATCC will likely establish air quality standards, requiring professional engineering.
Challenge 4: Staff Training
Requirements:
- Age verification procedures
- Dosing education for new consumers
- Overconsumption identification
- Emergency response protocols
- Product knowledge (different consumption methods, potency differences)
Cost: Initial training + ongoing education = $5,000-10,000 annually per venue.

Losers
Consumers wanting home delivery:
- SB 215 does nothing to authorize adult-use delivery
- Medical delivery extension is temporary (expires July 2026)
- Lounges don't solve access gap for rural consumers or mobility-impaired
Rural Maryland:
- Few if any consumption lounges will open in rural counties
- Benefits accrue primarily to urban/suburban residents and tourists
- Geographic disparity
Home-based consumers (neutral to negative):
- Lounges don't benefit consumers who already have private consumption spaces
- 63% of Maryland residents are homeowners with consumption rights
- SB 215 serves minority consumer segments
Budget-conscious consumers:
- Cover charges and premium pricing at lounges
- Illicit consumption (free at home) remains cheaper alternative
- SB 215 doesn't address price gap
Conservative municipalities:
- Pressure to approve consumption lounges despite local opposition
- Cultural concerns about "normalization"
- NIMBY activism
2026 Legislative Outlook: Will SB 215 Pass?
Probability of passage: 60-70%
Factors Favoring Passage
1. Solves real problem:
- Tourist consumption issue is genuine policy gap
- Renter consumption restrictions create access disparity
- Broadly recognized need
2. Social equity component:
- Priority licensing for disadvantaged communities
- Addresses racial equity concerns in cannabis policy
- Builds Democratic coalition support
3. Municipal opt-out provision:
- Allows conservative areas to prohibit lounges
- Reduces statewide opposition
- Political compromise built into bill structure
4. Precedent from other states:
- Colorado, Nevada, California, Massachusetts, New York all have consumption laws
- Maryland not first-mover risk
5. Medical delivery extension non-controversial:
- Medical patients and advocates support continuation
- No organized opposition to medical delivery
Factors Against Passage
1. Limited constituency:
- Primary beneficiaries (tourists, renters) have weak political voice
- Homeowners (63% of population) don't benefit
- Not a high-priority issue for most voters
2. Conservative opposition:
- "Normalization" concerns
- "What's next?" slippery slope arguments
- Law enforcement associations typically oppose
3. Business viability questions:
- Colorado's struggling lounge sector raises doubts
- Will anyone actually open lounges in Maryland?
- "Why pass a law for 10-20 venues statewide?"
4. Timing competition:
- Maryland faces bigger cannabis policy questions:
- Adult-use delivery authorization
- July 2025 tax increase (9% → 12%)
- Dispensary density expansion
- SB 215 may not be top priority
Most Likely Outcome
Scenario A (60% probability): SB 215 passes in 2026 session with modest amendments
- Minor changes to buffer distances or operating hours
- Bipartisan support (consumption venues less polarizing than legalization)
- Governor Moore signs (Democratic administration, criminal justice reform advocate)
Scenario B (30% probability): SB 215 stalls in committee
- Other cannabis priorities take precedence (delivery authorization, tax policy)
- Not killed but not advanced
- Possible reintroduction in 2027
Scenario C (10% probability): SB 215 fails outright
- Conservative opposition mobilizes
- Business viability concerns dominate
- Unlikely but possible
The Verdict: Pass SB 215, But Don't Stop There
Should Maryland pass SB 215?
YES—with full awareness of what it accomplishes and what it doesn't.
What SB 215 Accomplishes
- Solves tourist consumption problem (legal purchase + legal consumption venue)
- Provides renters with legal consumption alternative
- Creates social equity business opportunity (priority licensing)
- Modernizes Maryland's cannabis framework to match peer states
- Adds modest convenience improvement (+1 to +2 percentage points legal market share)
- Extends medical delivery (maintains patient access)
What SB 215 Does NOT Accomplish
- Does not authorize adult-use delivery (access gap remains for rural consumers, mobility-impaired)
- Does not increase dispensary density (1.6 per 100,000 vs. optimal 2.5-3.5)
- Does not address July 2025 tax increase (9% → 12%)
- Does not eliminate 280E federal tax penalty
- Does not enable SAFE Banking Act card payments
- Does not improve price competitiveness
- Benefits primarily urban residents and tourists (rural Maryland sees little impact)
The Honest Assessment
SB 215 is necessary but insufficient for Maryland cannabis market optimization.
Maryland's current 60-68% legal market share could reach 75-82% through comprehensive policy reform:
- Maintain 9% tax rate (resist July 2025 increase)
- Expand dispensary licensing (102 → 160-200 dispensaries)
- Authorize adult-use delivery statewide
- Pass SB 215 (consumption venues)
- Advocate for federal reform (Schedule III + SAFE Banking)
SB 215 alone improves Maryland's legal market share by 1-2 percentage points—worth doing, but it's one piece of a larger optimization strategy.
The framework verdict: Pass SB 215, celebrate the win, then immediately start working on adult-use delivery authorization and tax policy reform. Maryland needs consumption venues AND delivery expansion AND price competitiveness to complete its excellent cannabis launch.
Maryland built the foundation. SB 215 adds important infrastructure. But the building isn't finished until Maryland addresses access gaps, price competitiveness, and federal barriers.
