Grassroots RSO Review: Buyer’s Guide for 2026

Grassroots Cannabis, a Curaleaf-owned cannabis company, offers a premium selection of full-spectrum RSO products – namely syringes and capsules.

Similar to us, Grassroots makes their RSO products with actual full-spectrum extract, which preserves more cannabinoids and terpenes, instead of THC distillate

This difference means that Grassroots’s products are more potent and more effective than syringes or capsules made with distillate alone. 

The availability of their products completely depends on dispensaries which already have purchasing limits. However, if you have to travel out-of-state to find a dispensary that carries Grassroots RSO, the purchasing limit for most non-residents is significantly lower. 

Many dispensaries in Ohio, New Jersey, and Pennsylvania carry Grassroots products but you should research state laws around transporting cannabis products over state lines if you have to travel out-of-state.

In general, Grassroots is a good option for getting high-quality, high-potency RSO syringes and capsules.

 

Grassroots Overview

Grassroots Cannabis, though not a fully RSO-focused brand, offers two main, premium quality RSO products: 1g RSO syringes and 10mg-100mg RSO capsules.

You can purchase their RSO capsules in doses from 10-100mg per piece. 

If you’re new to RSO products, 10mg is slightly above the recommended dose for beginners so you can try taking only part of a capsule if you’re worried about taking too much at once.

The 25m per piece and higher options are better if you have a higher THC tolerance or are taking for serious medical conditions.

Their 1g RSO syringe is also good if you’re new to RSO products because it’s a very manageable amount. At RickSimpsonOil.com we recommend beginners to take a rice grain-sized dose and then wait 1-2 hours before taking more. Start low and increase your dose slowly.

Remember, most RSO products will be full-spectrum instead of distillate-based so even if the milligram dosing per capsule or gummy is the same, the RSO variant will produce stronger effects. 

Overall, Grassroots provides two solid options if you’re looking for high-quality RSO products.

Grassroots’s Most Popular RSO Products

Though Grassroots only has two RSO product categories, there are many flavor variants of their capsules and syringes.

Many customers talk about how good their Garlic Cookies RSO capsules are. Their Ray Charles capsules are also routinely praised for helping with sleep and restlessness in the evening.

In terms of their RSO syringes, Grassroots’s most popular option is their Singapore Sling RSO syringe, which can be added to food, mixed into beverages, or ingested directly.

Unlike RSO capsules, which you wouldn’t taste unless you broke the outer lining of the capsule, directly ingesting RSO from a syringe can be unpleasant if you aren’t used to the strong herbal, earthy flavor of the cannabis plant. Mixing it into food or flavored drinks is the best option if you don’t prefer its taste.

What People Think About Grassroots’s RSO Products

In general, many people online have good things to say about Grassroots RSO, as well as a few criticisms of certain attributes of their products

Potency

Some people have mentioned that their capsules are not very potent even after they’ve taken the higher dose (50mg+) options. One person mentioned that after taking a dose from one of Grassroot’s 1g RSO syringes, they didn’t feel anything until 3-4 hours later.

It’s important to understand that the effects you feel are based on a host of different factors. Some being, body weight, THC tolerance, whether you’ve consumed a fat-rich food recently (cannabinoids are fat-soluble), and how much you take at one time. 

More rarely, you will get a fluke product that hasn’t been dosed correctly by the manufacturer, but this is very uncommon and, typically, the effects you’ll feel depend on the factors above.

Convenience

Of the two major RSO products offered by Grassroots, most people prefer the capsule format because it offers more controlled dosing which means more predictable effects, is easier to take, and doesn’t have the strong herbal, earthy taste that pure RSO does. 

With syringes, you have to extract the oil carefully because taking too much can produce overwhelming effects and there isn’t a way to get the oil back into the syringe very easily. 

If you choose the syringe option, we tell customers to gently warm the syringe first so the oil is less viscous and easier to extract carefully. To do this, place the closed syringe in warm water or wrap a warm, damp cloth around the syringe and leave it for about five minutes.

Onset Time

Because syringes and capsules are both ingested and must undergo digestion to become effective, their onset time is fairly similar: 1-2 hours maximum.

For better absorption, eat a fat-rich food like a spoonful of peanut butter or a slice of pizza before you take your RSO. The cannabinoids in RSO are fat-soluble so the more fat you consume prior to ingestion, the better your system will absorb the RSO.

One person mentioned that the RSO capsules they got from Grassroots took up to 4 hours to set in fully. It’s important to realize that onset time varies person to person.

Sleep Support

Many customers have mentioned the Ray Charles RSO capsules from Grassroots as being especially helpful for sleep. 

Typically, a higher-dosed RSO product that’s made from an indica strain (like the Ray Charles strain) will be effective for this purpose.

Pricing

Because Grassroots is a premium cannabis brand, their capsules do cost more even without the added dispensary mark up.

The original cost plus whatever a dispensary (because Grassroot’s availability is dispensary-dependent) adds will raise the final price significantly.

Here’s a hint: Their RSO syringes are cheaper per gram than their capsules, so if you don’t mind working with syringes and would like a less pricey option, these may be right for you.

Availability

The availability of Grassroot’s products is completely dependent on dispensaries carrying them. 

This poses a problem if you don’t want to drive around to different dispensaries or search through a lot of online menus to find what you need. 

On top of that, if a dispensary that carries their products is not in your home state, odds are that there will be stricter purchasing limits for non-residents.

If you don’t mind doing that though be sure to check the state laws around transporting cannabis over state lines, even into states where cannabis is legal. 

Overall, Grassroots is a good option for getting good quality RSO products. The only downsides are availability, pricing, and their limited RSO product categories. 

Conclusion: Is Grassroots RSO Worth It?

Grassroots is a solid choice if you want full-spectrum RSO syringes and capsules that are – by most accounts – pretty effective. 

All of their RSO products are potent, and many come in a variety of strains and flavors so you can find an option you like. 

The biggest drawbacks are availability, pricing, and limited product variety compared to a dedicated RSO brand. 

If you can find Grassroots products near you, they’re worth considering, but always check dosing, dispensary rules, and local cannabis laws before buying.
