How Long Does CBD Take to Work?

The onset of effects from CBD products depends on the form of CBD you’re using.

The fastest onset of effects comes from inhaled forms of CBD (such as vapes or CBD flowers). Inhalation of CBD will result in benefits within 5 minutes, with the maximum effects reached in under 20 minutes.

For oral forms of CBD, the onset times can range from 30 to 60 minutes. This is because the active ingredients need to pass through the stomach and into the small intestine, where they can be absorbed. CBD is fat-soluble, which means there’s even an extra step. CBD is first absorbed into lymph fluid, which travels up near the heart where it finally enters the bloodstream.

If you’re using CBD oil or CBD gum, you can also allow the CBD to absorb sublingually (under the tongue). This can shorten the time needed for CBD to take effect to around 5 or 10 minutes. To do this, hold the CBD oil or CBD gum under the tongue for several minutes. The active ingredients will enter the bloodstream directly through the small capillaries on the underside of the tongue.
