Concentrates are cannabis products produced with a solvent to isolate active compounds or are manually concentrated using sieves or pressure. Concentrates have high potencies when compared with flower products and require specialized equipment to consume directly. Concentrates are best enjoyed through vaporization and usually have an immediate onset. On average the effects of concentrates last 1-3 hours with the typical peak experience occurring within 30 minutes. Description courtesy of iheartjane.com
