CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.
To obtain the CBD-packed hemp extract from its organic crop, Highland Pharms uses a process called “supercritical CO2 extraction.” This method eliminates the need for more harmful solvents, while it also, the company says, yields CBD oil of an outstanding purity and efficacy. Those wanting to see for themselves can take their pick from Highland Pharms’ positively reviewed variety of tinctures – the strongest concentration of which measures up at 1,250 mg – as well as capsules and edibles. And if those potential customers have no idea exactly how much CBD they should be imbibing, then they can get themselves up to speed at the Texas-based company’s website, which offers a user-friendly guide to serving sizes and methods of CBD oil intake, among other common queries.
If you live in a state where CBD is legal for your condition, it’s best to buy it from a state-regulated dispensary. But even there, oversight is uneven. “I feel safe being a cannabis consumer in Colorado, since the state tracks everything from seed to sale, but I didn’t the first few years after cannabis became legal,” when the rules were still taking shape, says Robyn Griggs Lawrence, the Boulder author of The Cannabis Kitchen Cookbook, which features recipes for cannabis edibles.

However, more and more often, there have been advertisements offering to ship CBD oil to your home, whether you live in Colorado or Kentucky, across state and federal lines. For those who are living in a state where cannabis is illegal, it may seem like a godsend to be able to order CBD oil over the Internet, shipped right to your house, but take a closer look at the product they’re selling.
