If you’re looking for Porter Square pre-rolls, The Boston Garden’s Cambridge store is at 200 Monsignor O’Brien Highway, a straight shot south from the square. Porter Square sits in north Cambridge with a Red Line stop and a commuter rail platform, so the trip is a short ride or a quick drive down Massachusetts Avenue. Anyone 21 or older with a valid government ID can shop.
Driving is easy too, because parking is free at every location, Cambridge included. That matters if you’re picking up a few packs of pre-rolls and don’t want to feed a meter in Kendall Square. Bring that ID either way, since it gets checked at the door every visit.

Why Porter Square Shoppers Head South
Porter Square is a transit stop and a shopping strip, not a dispensary address. It sits between Harvard Square, Davis Square, and Union Square, each one within a couple of miles by bus, bike, or car.
Three stores serve the wider area: Cambridge near Kendall Square, Somerville near Union Square, and Athol on Main Street in north central Massachusetts. For most people coming from Porter Square, Cambridge is the short run down Massachusetts Avenue, and recreational cannabis near Union Square, Somerville is the better fit if you’re already heading that direction.
| City | Address | Phone |
|---|---|---|
| Cambridge | 200 Monsignor O’Brien Highway, Cambridge, MA 02141 | 857-588-1301 |
| Somerville | 524 Somerville Ave, Somerville, MA 02143 | 617-591-5060 |
| Athol | 946 Main Street, Athol, MA 01331 | 978-593-0900 |
Each store keeps its own live menu online, and all three take orders for in-store pickup. That means you can compare single joints and pre-roll bundles before you leave, then call the shop if you want a budtender to confirm a brand or pack size.
Getting From Porter Square to the Cambridge Store
By car, head south on Massachusetts Avenue, then cut east toward Monsignor O’Brien Highway as you near the Charles. The last stretch runs past Lechmere and East Cambridge, so you’re there in about ten minutes outside rush hour.
On the T, take the Red Line inbound to Kendall/MIT and walk north, or connect toward the Lechmere side and walk in from there. Either way it’s a short walk at the end. On a bike, the run down Beacon Street or Mass Ave is flat and under three miles.
- Car: south on Mass Ave, east to Monsignor O’Brien Highway
- Red Line: Porter to Kendall/MIT, then walk
- Bike: Beacon Street or Mass Ave, under three miles
- Bus and walk: good option if you’re already near Union Square
Free parking at the Cambridge location means no circling the block for a meter. Call 857-588-1301 if you want to confirm hours before you head out. And plan your travel for before use, never after.
Checking the Live Pre-Roll Menu Before You Go
Each store keeps its own live menu, so select Cambridge first or you’ll be looking at stock sitting in Somerville or Athol. From there, filter to pre-rolls and sort by price or brand to cut the list down fast.
Stock rotates as batches land and sell through, so a tube you saw last week may be gone. The menu is the accurate source, not an older post or a friend’s memory.
- Pick the Cambridge store on the menu
- Filter to pre-rolls, then sort by price or brand
- Compare single rolls against multipacks
- Open the specials page the same visit
- Place the order for in-store pickup
Rotating specials run at all three stores, so it’s worth a look before you build your cart. If you want to compare single pre-rolls and multipacks near Cambridge in more depth, that breakdown is worth a read first. Loyalty club sign-up is available at the Cambridge and Athol locations.
Single Rolls, Multipacks, and Infused Options
A single roll is one ready-to-go cone, which makes it the cheapest way to try a strain you haven’t had. Multipacks hold several smaller rolls in one tube or tin, usually at a lower price per gram than buying singles one at a time.
Infused pre-rolls add concentrate to the flower, and the label on the tube will say so plainly. Strain names are a starting point, not a promise, since descriptions differ by grower and batch.
| Format | Pack style | Check on the label |
|---|---|---|
| Single roll | One cone, tube or doob | Weight and strain name |
| Multipack | Tin or tube, several rolls | Count and per-roll weight |
| Infused roll | Often sold in twos | Concentrate type listed |
Ask a budtender which batches just landed if you want something fresh off the truck.
ID, Discounts, and What Happens at the Door
A valid government ID showing you are 21 or older is required every visit, with no exceptions for regulars. Massachusetts rules mean medical marijuana cards can’t be accepted at the register, though anyone 21 or older is welcome to shop.
Discounts apply on top of that, and you only need to show the right ID at the counter.
- 15% off every visit for veterans with valid military ID
- 15% off for medical card holders with a valid card
- 15% off for cannabis industry professionals with valid ID
- 10% off every visit for anyone over 55 with valid ID
Pickup is quick. Give your name, confirm the order on the screen, pay, and go. If something about your order needs sorting out, call 857-588-1301 before you make the drive rather than after you arrive.
Purchase limits are set by Massachusetts regulators, not by the shop, so ask staff at the counter or look at current state regulations if you’re buying for more than one trip.
Cambridge or Somerville for Your Pre-Roll Run
From Porter Square, the shop on Somerville Ave near Union Square sits about as close as the one on Monsignor O’Brien Highway. Direction of travel decides this more than mileage does.
Take the Monsignor O’Brien Highway side if the rest of your day points toward Lechmere, Kendall, or a river crossing, and skip it at 5pm when that road backs up. Go up to Union Square instead if you’re already running errands in that part of Somerville. Stock is the other half of the call, because the tube you want may be listed at one store and not the other.
| Store | Pick it if | Trade-off |
|---|---|---|
| 200 Monsignor O’Brien Hwy | Errands near Kendall or Lechmere | Slow at rush hour |
| 524 Somerville Ave | Already near Union Square | Separate pre-roll list |
| 946 Main Street, Athol | Driving west on Route 2 | Far from Porter Square |
Both nearby stores take online orders for in-store pickup, and both have free parking, so the real cost of picking wrong is a crosstown drive. Ring 617-591-5060 for the Somerville Ave store if you want a brand confirmed first, or compare the Somerville deals on vapes, edibles, and pre-rolls against the Cambridge list. Sort out your ride home at the same time you pick the store, since getting behind the wheel after use is off the table.
Lock In Your Cambridge Pickup Order
Pull up the Cambridge menu, filter to pre-rolls, and put the order in before you walk out the door, because that is the only way to know what is actually on the shelf when you arrive. Scan the specials on the same visit, since both the stock list and the offers move. Then grab your ID, plus whatever discount ID you qualify for, and point yourself toward 200 Monsignor O’Brien Highway. Parking is free, so you are not hunting for a space once you get there. If anything on the list is unclear, 857-588-1301 reaches the store and a budtender can answer it faster than a second round of menu scrolling.
Pre-Roll Questions From Porter Square
How long will my pickup order be held before it goes back on the shelf?
Hold times are set by the store, so call 857-588-1301 and ask when you place an order you can’t collect right away. Staff at the counter can tell you how long your name stays on the bag. If plans change, a quick phone call is better than letting the order sit, since popular tubes sell through fast.
What is the best way to store pre-rolls at home so they don’t dry out?
Keep them in the sealed tube or tin they came in, somewhere cool and out of direct sun. The packaging is built to hold moisture, so opening a multipack tin and leaving it open is what dries the rolls out. Store everything where people under 21 can’t reach it, and keep it away from heat sources like a radiator or a sunny windowsill.
How do I pick a brand when I’ve never heard of any of the names on the menu?
Start with a single roll from a brand you don’t know rather than a multipack, so you’re risking less on an unknown. Ask a budtender which brands move fastest at the Cambridge store, since turnover tells you what regulars come back for. Our in-house brand, Lobster Pot, is another starting point if you want something the shop stands behind.
Can I carry my sealed pre-roll purchase home on the Red Line?
Massachusetts rules govern how cannabis is carried in public, and the MBTA sets its own policies for riders, so check current state regulations and transit rules before you travel. Keep the packaging sealed and the bag closed either way. Using the product on a train, platform, or any public space is not allowed. A budtender can walk you through what the exit bag is for.
