THCA Joints: Pre-Rolled, Lab-Tested, Ready to Spark

Our THCA joints are hand-rolled with whole-flower THCA — never trim, never shake. Every batch arrives with a current COA so you know exactly what you're smoking. When THCA is heated, it converts to active Delta-9 THC, delivering the experience seasoned smokers expect from a top-tier Sun Prairie Dispensary.

THCA Flower: Top-Shelf Buds, Dispensary Pricing

Browse jars of frosted, hand-trimmed THCA flower in eighths, quarters, halves, and ounces. Strains rotate weekly so our Hwy 151 Dispensary always has something new for repeat customers.

How GreenRX™ Sun Prairie Compares to Other Dispensaries

Wisconsin shoppers have options — but a true Sun Prairie Dispensary needs to deliver on three things: product depth, compliance, and price. GreenRX™ owns all three. Our sister shops, including GreenRX™ Baraboo and GreenRX™ Reedsburg, share the same sourcing standards — but Sun Prairie carries the biggest in-store inventory thanks to its Hwy 151 traffic flow.

What Local Customers Say

"Best THCA flower I've found between Madison and Milwaukee. The Hwy 151 location makes it a no-brainer stop." — Verified Sun Prairie customer

THCA, Delta-9 & The Wisconsin Hemp Law — Quick Primer

THCA is the raw, non-psychoactive cannabinoid found in living cannabis. Once heat is applied (lighter, vape, oven), THCA decarboxylates into Delta-9 THC. Because our THCA joints and THCA flower test under 0.3% Delta-9 by dry weight, they qualify as federally compliant hemp under the 2018 Farm Bill — and they're sold legally at every GreenRX™ Sun Prairie Dispensary checkout.

Lab Testing & Compliance

Every product on our shelves carries a third-party Certificate of Analysis. Ask any budtender for a printed COA or scan the QR code on the package.
