Santa Fe Cannabis Limits
New Mexico Purchase Limits in Santa Fe, Explained Clearly
If you are shopping in Santa Fe, these are the same statewide New Mexico limits that apply everywhere: adult-use transaction caps plus medical unit tracking over a rolling 90-day window.
Medical Program (Rolling 90 Days)
- Medical patients can buy up to 425 units (about 15 ounces) over a rolling 90-day period.
- Medical purchases are generally tax-exempt until the medical unit limit is reached.
- When medical units are exhausted, qualifying shoppers 21+ can still buy through adult-use transactions (tax applies).
How Medical Units Work
Simple unit math
- 1 unit = 1 gram of dried flower.
- For edibles, oils, tinctures, concentrates, and topicals, 1 unit = 200 mg of THC.
- Unit tracking is rolling: each day, purchases older than 90 days drop off and units return.
Quick formula for non-flower products: THC milligrams ÷ 200 = units.
Why This Matters
This page is built for Santa Fe shoppers who want limit clarity before checkout. The city does not run a separate consumer purchase-limit system; purchase limits are set by New Mexico law and statewide regulators.
City-level cannabis rules in Santa Fe mainly govern commercial operation details such as location, zoning, and hours for licensed businesses.
If you are planning a larger medical purchase, checking your current medical units first helps prevent surprise tax changes at checkout.
Unit Examples
Common conversions at checkout
| Product Example | Units | How It Is Calculated |
|---|---|---|
| 3.5g flower | 3.5 units | Flower units map directly to grams. |
| 100 mg edible package (total THC) | 0.5 units | 100 mg ÷ 200 mg per unit = 0.5. |
| 500 mg THC tincture | 2.5 units | 500 mg ÷ 200 mg per unit = 2.5. |
| 1000 mg THC concentrate | 5 units | 1000 mg ÷ 200 mg per unit = 5. |
