Updated June 2026
As of April 17, 2026, adults 21+ can purchase up to 2 ounces (56 grams) of cannabis per day in Massachusetts — double the previous 1-ounce limit. This applies to flower or its equivalent in concentrates and edibles, combined.
How the conversion works
Not every product counts the same toward your daily limit. Massachusetts uses a flower-equivalency system:
- 1 oz of flower = 5 grams of concentrate (vapes, dabs, tinctures, hash)
- 1 oz of flower = 500mg of THC in edibles
- Topicals are unlimited — no daily cap
So your 2 oz daily limit translates to 10 grams of concentrate or 1,000mg of edibles, if that’s all you’re buying — or any mix that adds up to 2 oz in flower-equivalent terms.
Here’s the law, as written
500.140(3)(a): “…a Marijuana Retailer shall not knowingly sell more than two ounces of Marijuana or its combined dry weight equivalent in Marijuana concentrate or Edible Marijuana Products to a retail customer per day.”
1. One ounce of flower = 5 grams of active THC in concentrate, including tinctures.
2. One ounce of flower = 500mg of active THC in edibles.
3. Topicals and ointments are not subject to a daily sales limit.
A real example
Let’s say Tommy’s stocking up for the weekend with some current favorites:
- In House Blueberry Gummies (100mg) — 5.6g flower-equivalent
- Nature’s Heritage Spark Mycro Dose Pills (100mg) — 5.6g
- Fernway Red Headed Stranger Vape Cartridge (1g) — 5.6g
- Jeeter American Pi Baby Jeeter 5-Pack (2.5g) — 2.5g
- In House PB & Smelly Flower (7g) — 7.0g
- Total: 26.3g / 56g
Under the new 2 oz limit, Tommy’s well within range — and could nearly double this order before hitting the cap.
Why does a 100mg edible “weigh” the same as 1g of concentrate?
It’s one of the more counterintuitive parts of MA cannabis law. The limits aren’t based on raw weight — they’re based on estimated THC potency, using flower’s average ~17.8% THC as the baseline. So a small, potent edible or concentrate can use up daily allotment fast compared to flower.
