THC Vape vs Edibles: Onset, Dose, Duration

THC Vape vs Edibles

Two delivery methods, two timelines. Inhaled THC and oral THC differ in onset, peak, and duration. The numbers below come from state label rules and federal health agencies.

The Pick

Pick a THC vape for fast onset and a short session. Pick edibles for a long session and a body-heavy effect. Vape onset runs 2 to 10 minutes. Edible onset runs 30 to 120 minutes.

Vape: onset 2 to 10 minutes. Peak 15 to 30 minutes. Duration 1 to 3 hours.
Edible: onset 30 to 120 minutes. Peak 2 to 4 hours. Duration 4 to 8 hours.
Inhaled bioavailability: 10 to 35 percent. Oral bioavailability: 4 to 12 percent.

Liver enzymes convert edible THC to 11-hydroxy-THC. That metabolite crosses the blood-brain barrier. Users report a stronger effect per milligram.

Dose and Potency

Vape cartridge: 70 to 90 percent THC by weight. A 1-gram cart holds 700 to 900 mg THC. One 3-second pull delivers about 1 to 3 mg THC.
Edible: 5 to 10 mg THC per serving. Colorado sets 10 mg as one adult dose.
Package limits: 100 mg THC per edible package in Colorado. 8 grams of concentrate per day for recreational purchase in Colorado.

Risks

Vape: EVALI cases in 2019 linked to vitamin E acetate in illicit cartridges. CDC found the additive in 29 of 29 lung fluid samples from 10 states.
Edible: delayed onset leads to repeat dosing. A second 10 mg dose at 30 minutes can stack with the first dose at 2 hours.
Both: impaired driving, memory, and coordination. THC stays in blood for hours, in urine for days.

Options

Vape options

Look for live resin, cured resin, and distillate carts. Live resin keeps terpenes. Distillate runs 85 to 95 percent THC. Check the batch test for pesticides, residual solvents, and heavy metals.

Edible options

Gummies, chocolates, and beverages. Gummies dose in 2.5, 5, and 10 mg units. Chocolates dose in 10 mg squares. Beverages act in 15 to 30 minutes because of emulsified THC.

How to Choose

Match the method to the window. A 90-minute movie fits a vape. A 6-hour event fits an edible. Start low. Wait the full onset window before a second dose.
