Chemistry is a Northern California cannabis-extract brand founded by organic chemist Paul Roethle. Its identity is built around small-batch, sun-grown flower, single-origin full-spectrum oil and extraction methods designed to avoid the standard CO2, hydrocarbon and ethanol routes. Garden Society acquired Chemistry in an all-equity deal in February 2024, bringing the brand into a larger California manufacturing portfolio.
Founder and origin
Roethle holds a PhD in organic chemistry from UC Berkeley and previously worked on antiviral treatments at Gilead. A 2019 letter on Chemistry’s site says the company was founded in 2015; the 2024 acquisition announcement describes Chemistry and Garden Society as established in 2016. Because those first-party dates conflict, the profile records the 2015 founding claim and flags 2016 as the acquisition announcement’s alternate public date.
“Stay True to the Plant”
Chemistry’s core process starts with a single cultivar from one farm’s harvest for each batch. The company says a portion is steam-distilled to capture terpene oil, then reunited through a mild refinement method that does not use CO2, butane, propane or ethanol as the primary extraction route. It positions the result as full-spectrum and explicitly “not distillate.”
That language describes Chemistry’s process and philosophy; it does not prove that full-spectrum oil produces a particular medical outcome. Batch-specific cannabinoid and terpene results still belong to the package and certificate tied to the lot.
Farm relationships and sustainability
The brand has worked with Northern California farms including Moon Made Farms and Emerald Spirit Botanicals. Chemistry says partner farms use organic cultivation techniques, with some carrying Sun+Earth certification. It also describes solvent recovery, reuse, byproduct repurposing and energy-efficiency measures inside manufacturing.
“Organic techniques” is not the same thing as USDA organic certification for a cannabis product. Certifications should be attached to the named farm and date rather than extended to every Chemistry release.
Current tincture lineup
The live Products page currently foregrounds six color-coded tinctures: Green 18:1 CBD, Yellow 5:1 CBD, Orange 3:1 CBD, Pink 1:1, Purple 1:3 THC and Blue 1:10 THC. The ratios are product identifiers, not dosing guidance, and the exact milligrams and ingredients should be read from the current label.
Vapes, legacy releases and collaborations
Chemistry’s archive contains strain-specific full-spectrum vape pages tied to named farms, along with formulas such as Moon Beam and earlier tincture releases such as AC/DC. Some pages preserve release dates and historic lab values from 2018–2023. They document the brand’s catalog history but do not establish that every cartridge or batch remains on sale.
Project Fusion, launched in 2021, used infused pre-rolls to support partner causes. The current site’s main product grid does not list pre-rolls, so the profile treats that format as a documented campaign rather than an always-active product family.
Garden Society acquisition
Garden Society acquired Chemistry in February 2024 through an all-equity transaction. The announcement said Chemistry would add tinctures, cartridges and other artisanal categories to Garden Society’s manufacturing and distribution platform in California and planned markets. Roethle joined Garden Society’s executive team as vice president of product.
Ownership and brand identity are separate: Chemistry continues to maintain its own site and “Stay True to the Plant” positioning, while Garden Society is the current parent named in the acquisition record.
Awards and recognition
Chemistry’s AC/DC product page records a third-place finish in the CBD Edible category at the 2018 High Times World Cannabis Cup for an earlier version of that tincture. That is a product-level award with a named year and category. General press praise is not expanded into additional awards without an itemized result.
License and safety claims
The live site displays California manufacturing license C12-0000062-LIC and says products are tested for pesticides, heavy metals and residual solvents at key manufacturing stages. License status should be rechecked in California’s official database; a website footer alone does not prove uninterrupted current standing.
Chemistry reported that tested vape samples were non-detect for vitamin E acetate in 2019. That result applied to the sampled cartridges and detection limit at that time, not to every future product.

- Chemistry’s About and Products pages establish its process, farm model, license display and current tincture grid.
- Roethle’s 2019 letter supplies the founder’s name, credentials and 2015 founding claim.
- The February 2024 acquisition announcement establishes Garden Society ownership and Roethle’s post-deal role.
- Historic product pages support named releases and the 2018 AC/DC award, but are not treated as live inventory.
