Along with this change, the state has also increased the allowable limits for edibles, vapes, and concentrates, making this one of the most significant updates to cannabis law in recent years.
For customers visiting a cannabis dispensary in Nantucket, here’s what you need to know.
What Changed in Massachusetts Cannabis Law?
The updated law increases limits across multiple product categories, including: 
- Flower: Up to 56 grams (2 ounces)
- Edibles: Increased allowable THC limits
- Vapes & Concentrates: Higher purchase and possession thresholds
Previously, these limits were roughly half of what is now allowed. The new law provides more flexibility for customers across all cannabis product types.
What This Means for Nantucket Dispensary Customers
If you’re shopping at a cannabis dispensary in Nantucket, Ack Natural, you may not immediately see these new limits reflected at checkout.
That’s because dispensaries must still follow:
- State compliance systems
- Product equivalency rules
- POS and METRC tracking
As a result:
- Purchase limits may still appear lower temporarily
- Different products (flower, edibles, vapes) are still calculated differently
- System updates may roll out gradually
Understanding Cannabis Purchase Limits
Cannabis purchases in Massachusetts are based on THC equivalency, not just total weight.
This means:
- Edibles are calculated by THC content
- Concentrates and vapes count differently than flower
- A mix of products can reach your limit faster than expected
Even though limits have doubled, how much you can purchase depends on the combination of products you select.
