California’s legal marijuana market closed out 2025 with $348 million in sales during December, marking the strongest month of the year, according to new data from research firm Headset. The December total pushed full-year sales to approximately $3.64 billion, a figure that came in about 15% below the $4.27 billion recorded in 2024.

Despite the year-over-year decline in overall revenue, Headset data show that falling prices played a major role in the reduced total. The average price per gram of dried marijuana flower dropped more than 22% over the past year, declining from $9.49 to $7.30.

December stood out as the highest-grossing month of 2025, while February marked the slowest period of the year at $306 million in total sales. Headset also reported that Blue Dream was the top-selling strain statewide during December, maintaining its long-standing popularity among California consumers.

Flower remained the largest category in December, generating $106.76 million in sales, though that figure was down 2.0% from the same month a year earlier. Vapor pens followed closely at $103.07 million, posting a 1.9% year-over-year increase. Pre-rolls continued to gain ground, bringing in $62.23 million, up 3.8%, while edible products totaled $42.72 million, reflecting a 6.0% increase.

Concentrates saw $17.14 million in sales, down 7.3% year over year. Beverages, while still a smaller segment, recorded $7.99 million in December sales and posted the fastest growth rate, jumping 22.7%. Capsules declined sharply to $3.63 million, down 38.9%, while tinctures and sublingual products rose modestly to $2.96 million, up 4.6%. Topical products rounded out the market with $1.85 million in sales, down 3.1%.

The data underscore a year defined by price compression and shifting consumer preferences, even as California’s legal marijuana market continues to generate billions annually.
