Michigan's 24% Wholesale Cannabis Tax: What the Data Shows

Overview

In January 2026, Michigan introduced a 24% wholesale cannabis tax applied to transactions between cultivators/processors and retailers. By raising the cost basis upstream, the policy created immediate pricing pressure before products ever reached consumers. Our data suggests the effects were both swift and significant — and that the market has since stabilized at a new, lower baseline.

A Sharp January Contraction

‍

‍

Michigan's cannabis market declined sharply in January 2026. Total sales fell 15.9%, from $269.6M to $226.8M, while unit volume dropped 17.6%, from 31.3M to 25.7M units. Every major product category posted double-digit declines:

• Edibles: -19.3% sales, -21.9% units
• Pre-Rolls: -16.5% sales, -16.3% units
• Vapor Pens: -14.9% sales, -18.1% units

Unlike typical market softness, where declines in one category are often offset by gains elsewhere, no category was spared.

How Retailers Responded

Faced with higher upstream costs, retailers appear to have passed much of the burden to consumers through two mechanisms: raising list prices and pulling back on promotional discounting.

Average item prices rose 2.1% overall, with the steepest increases in Tinctures & Sublinguals (+8.5%), Topicals (+4.2%), Vapor Pens (+3.9%), Beverages (+3.6%), and Edibles (+3.3%). At the same time, total discount spending fell 28.2% — from $101.3M to $72.7M — and the average discount rate dropped from 27.3% to 24.3%, an 11.1-point reduction.

The discount pullback may be the more consequential of the two shifts. Consumers who had come to rely on promotional pricing saw effective prices rise even in categories where list prices held relatively steady. Pre-Rolls, for example, saw flat list prices but a 15.4-point cut to discount rates — coinciding with a 16.3% drop in unit volume.

Michigan as a National Outlier

Comparing Michigan to other US state markets over the same period provides useful context. While January typically brings some post-holiday softness, no other tracked state came close to Michigan's decline:

The US average (excluding Michigan) was -4.4% in sales and -5.5% in units. Michigan's declines were 3.6x and 3.2x worse, respectively. Seasonal factors alone are unlikely to account for a gap of that magnitude.

February: Stabilization at a New Baseline

Early February 2026 data suggests the market has stopped contracting, but has not recovered. On a daily average basis, sales are essentially flat month-over-month ($7.32M → $7.29M, -0.4%), as are unit volumes (830K → 823K, -0.9%). Seven of nine tracked categories show daily sales within ±2% of January levels.

Critically, the pricing and discounting adjustments made in January appear to be holding. Average item prices have remained stable or slightly higher across most categories, and discount rates have settled around 32-33% — higher than January's trough, but still well below December's pre-tax levels. There is no indication of retailers aggressively discounting to recapture lost volume.

The February data is consistent with the January decline representing a demand reset rather than the start of an ongoing contraction. Consumers appear to have adjusted to the new effective price level, but those who reduced purchasing or left the market in January have not returned.

What the Data Suggests

Taken together, the January and February data point to a tax pass-through scenario in which retailer cost increases were transmitted to consumers through higher prices and reduced promotions, resulting in a one-time but persistent reduction in market size. Michigan's cannabis market now appears to be operating at a level roughly 16-18% below its December 2025 baseline.

At Headset, we will continue monitoring the data in the coming months to assess whether any recovery emerges, or whether this new equilibrium holds.
