The method used to Extract CBD from hemp has a big impact on its quality. Since CO2 extraction maintains the compound's purity without the use of hazardous solvents, it is regarded as the gold standard. Steer clear of tinctures made using butane or ethanol extraction methods as they can include substances that have been left behind.

Reputable CBD companies always put their products through independent lab testing to confirm their purity and potency. Make sure a CBD oil tincture has a Certificate of Analysis (COA) before acquiring one online.
