Premium Rick Simpson Oil (RSO): Full-Spectrum Whole-Plant Extract

Premium Rick Simpson Oil (RSO) is a thick, dark, full-spectrum extract made from whole cannabis plants, supplied in a graduated syringe so you can measure precise doses. It’s one of the strongest formats we carry, and it’s taken orally rather than smoked. A straightforward way to buy RSO online in Canada.

Flavour, Aroma & Effects

RSO tastes like the plant it came from: earthy, herbal and bitter, with a pungent resinous aroma. Nobody buys it for flavour. Taken orally, the onset is slow — typically 45 to 90 minutes — and the effects are strong, body-heavy and long-lasting, often several hours. Dose carefully and never re-dose early.

Grade & Format

This is a full-spectrum extract, meaning it retains the plant’s broader cannabinoid and terpene profile rather than isolating THC. It ships in a graduated syringe, which is the standard RSO format and the easiest way to measure a rice-grain dose. Compare our other oil and concentrates.

Storage Recommendations

Store the syringe sealed, upright and somewhere cool and dark. RSO thickens considerably when cold, so warm the syringe in your hands or in a cup of warm water for a minute before dispensing. Keep it well out of reach of children and pets: a small amount carries a very large dose. Read whether cannabis loses potency over time.

Frequently Asked Questions

What is Rick Simpson Oil?

Rick Simpson Oil, or RSO, is a thick, dark, full-spectrum cannabis extract made from whole plants and named after the Canadian who popularised the method. It’s typically 60–90% THC, retains a broad cannabinoid and terpene profile, and is usually taken orally from a syringe rather than smoked.

How do you take RSO?

Most people take it orally: squeeze a small amount onto a fingertip or into a capsule and swallow it, or spread it on food. It can also be placed under the tongue. Onset takes 45 to 90 minutes, so wait a full two hours before considering more.

How much RSO should you take?

The standard starting point is a dose about the size of a grain of rice, or smaller. RSO is far stronger than smoked cannabis and the effects last hours, so starting too high is the most common mistake. Begin small, take it in the evening, and increase slowly if at all.

What’s the difference between RSO and distillate?

Distillate is refined down to nearly pure THC, so it’s clear, nearly flavourless and usually vaped. RSO is unrefined and full-spectrum: dark, bitter and thick, keeping more of the plant’s compounds. RSO is for oral use, distillate mostly for inhalation.

Does RSO cure cancer?

No. There is no reliable clinical evidence that RSO treats or cures cancer, and it should never replace medical treatment. Some early laboratory research on cannabinoids exists, but it doesn’t support the claims made online. If you’re managing a serious illness, talk to your doctor before using any cannabis product.
