MICHIGAN— Rick Simpson Oil (RSO) has been a cannabis staple for decades. 

Thick, tar-like, and famously full-spectrum, RSO is a full-extract cannabis oil that’s usually packaged in a syringe and has earned its place in cannabis culture as both a healing medicine and a grassroots movement. It can also be messy, harsh if you try to smoke it, and made with dangerous solvents—like grain alcohol or butane—that raise questions over stoner safety. 

Enter Wojo Solventless Oil.

Think of Wojo Solventless Oil—or WSO, for short—as a modern-day upgrade to RSO. It’s solventless, fully activated, lab tested, and versatile as hell. Plus, it’s all made in-house from Wojo brand flower using only chilled, reverse-osmosis water instead of ethanol or butane.

The result is a new, full-spectrum extract with intact terpenes and cannabinoids, minus the plant fats and chemical residue that so often comes along for the ride in traditional versions of RSO.

And most importantly? WSO isn’t limited to oral or topical use. You can eat it, smoke it, dab it, or rub it on your elbow—whatever works best for your body. And as a solventless, smoke-ready alternative to RSO, that makes this product a genuine gamechanger for the concentrate marker.

Putting it to the test

I picked up a few samples at First Class Cannabis Co. in Lansing. 

For me, the versatility was the real selling point. I tried it in every way imaginable—including squeezed into the center of a joint; drizzled on top of a bowl; dabbed off a rig; swallowed raw; even smeared on an Oreo cookie for good measure. And each time, WSO delivered.

The high was wild in its range. Edible-style, it crept in slow and heavy, providing the kind of couch-locking buzz that’s perfect for a movie night. When smoked, it came on fast—like a dab, but smoother, and with a relaxing buzz that made me more chatty than lazy. Same syringe, two different vibes, and both hit harder (and cleaner) than anything I’ve tried in this lane before.

Dispensaries sold out of the first batch of WSO sold out almost instantly, which makes sense.

This isn’t just another product; it’s a new category. RSO will always have its place, but this gives patients and stoners a new, clean, flexible option with the same kind of therapeutic punch.

The bottom line

RSO is legendary for a reason, and it’s clear that Wojo isn’t trying to erase that history. What they’ve done is modernize it—building on Rick Simpson’s legacy while offering something cleaner, safer, and more user-friendly. It’s respect and innovation, all rolled into one syringe.

My take? Wojo’s Solventless Oil is truly one of the most exciting new products to hit Michigan shelves in years. It honors the past while pushing marijuana medicine into the future. And it might have just set the new standard for how full-spectrum cannabis oil should be made.
