Harvesting the Best Marijuana Has to Offer

Our proprietary method of extracting cannabinoids generates a higher level of effect-based or strain-specific extracts that can be concentrated into oils, waxes, edibles, and shatter. We believe this proprietary process and the ability to manufacture these refined cannabinoids provide us with a strategic advantage in the cannabis industry.

Proprietary Methods of Extraction and Conversion

Ray Keller, a shareholder of CLS, and a founder of CLS Labs, developed our US patented proprietary process for extracting, cleaning, and converting cannabinoids from cannabis plants. This proprietary extraction and conversion methodology allows for cannabinoid concentrates to be ingested in several ways, including through vaporization and used for a variety of pharmaceutical and other purposes.

Competitive Advantages

Our proprietary process produces a cleaner, higher quality product, and a significantly higher yield than most cannabinoid extraction processes currently existing in the marketplace.
