How quickly CBD feels depends on delivery: vaporized or smoked buds enter bloodstream in two to five minutes; sublingual drops take 15–45 minutes; edibles and beverages need 30–90 minutes. Empty‑stomach use, higher potency, and faster metabolism shorten perceived onset.

After the last dose, most CBD clears the body within three to seven days, based on an 18‑ to 32‑hour half‑life. Frequent high‑dose users can retain cannabinoids in fat stores, prolonging elimination to two, sometimes four, weeks before undetectable levels.

Placed under the tongue, CBD oil usually absorbs in 15–45 minutes as capillaries in oral tissues bypass digestion. When swallowed with food or capsules, onset slows to 30–90 minutes because cannabinoids must survive stomach acid and first‑pass liver metabolism before entering circulation.

CBD effects generally last 2–6 hours. Inhaled vapor peaks quickly and fades within about three hours; sublingual oils hold four to six; edibles or capsules build slowly but can linger six to eight. Dosage, metabolism, and body weight extend or shorten that window.
