When cannabis is inhaled the effects are felt quickly, peaking within 30 minutes, lasting up to 6 hours. Inhaled cannabis has a different metabolic process than when you ingest it. Ingested cannabis must first travel to your stomach then to your liver before getting into your bloodstream and brain. When eaten, the same amount of cannabis will deliver more potent effects than when inhaled. When you eat or drink cannabis, you will feel its effects within 2 hours, with full effects peaking within 4 hours and lasting up to 24 hours. Edibles have enhanced bioavailability and greater potency in comparison to inhaled cannabis.
