The Five Major Cities
| City / County | Pop. | Why It Matters |
|---|---|---|
| Manchester / Hillsborough | ~115,000 | Largest city; Sanctuary ATC nearby; major employer base |
| Nashua / Hillsborough | ~91,000 | 2nd-largest; 5 min to MA dispensaries; most cross-border-driven city |
| Concord / Merrimack | ~44,000 | State capital; legislative news anchor; Temescal Wellness ATC |
| Portsmouth / Rockingham | ~22,000 | Pease Tradeport (federal employment); 5 min to Maine |
| Lebanon & Hanover / Grafton | ~26,000 combined | Dartmouth College; 5 min to Vermont via White River Junction |
The Geographic Pattern
What’s striking about New Hampshire is how compressed the geography is — and how every population center sits close to a legal-cannabis border:
- Salem & Nashua are 5–10 minutes from Massachusetts dispensary clusters in Tyngsborough, Methuen, Salisbury, Lawrence, and Haverhill
- Portsmouth is 5 minutes from Kittery, Maine, where multiple recreational dispensaries operate
- Lebanon & Hanover are 5 minutes from White River Junction, Vermont, with Vermont retailers along the Connecticut River
- Keene is 30 minutes to either Brattleboro VT or Greenfield MA
Only the more rural Lakes Region and White Mountains require longer drives — though Plymouth and Conway residents still reach Maine retailers within an hour.
Federal Employment Concentrations
Several NH cities have unusually heavy federal-employment concentrations that shape workplace cannabis policy:
- Pease Tradeport / Pease Air National Guard Base (Portsmouth) — 157th Air Refueling Wing, federal contractors, ~7,000 jobs across the tradeport ecosystem
- Portsmouth Naval Shipyard (Kittery, ME but workforce drawn from NH seacoast) — submarine maintenance, ~6,000 jobs
- Hanscom AFB (Bedford, MA but NH commuter base)
- BAE Systems (Hudson, Merrimack) — major federal defense contractor
- Sig Sauer (Newington) — federal firearms/defense contractor
- DEKA Research (Manchester) — federal R&D contracts
All these employers operate under the federal Drug-Free Workplace Act of 1988. Security clearance positions are governed by SF-86 question 23: any cannabis use must be disclosed; current use is disqualifying; state TCP card status provides no defense. RSA 126-X:2-a provides limited NH employment protection for medical cardholders against discriminatory action, but it does not preempt federal contractor or security-clearance requirements.
The Five ATCs by Region
The five Alternative Treatment Centers are distributed to provide reasonable patient access:
- Sanctuary ATC — Plymouth (Lakes Region) and Conway (White Mountains)
- Temescal Wellness — Lebanon (Upper Valley) and Dover (Strafford County)
- Prime Alternative Treatment Centers — Merrimack (south central) and Peterborough (Monadnock)
- GraniteLeaf Cannabis — Concord/area locations
- Live Free Cannabis (formerly Solar Therapeutics) — locations
