How long do delta 9 THC gummy’s effects last?

Since delta 9 THC is metabolized differently when ingested versus inhaled, the length of effects varies considerably between gummies versus smoking or vaping weed. Here’s an overview of how long you expect to feel delta 9 THC gummy effects based on dosage as well as other factors that influence duration.

Typical duration of effects by dose

Due to the delayed onset of ingested THC passing through the digestive system, delta 9 THC gummies typically provide a longer high compared to rapid effects from smoking or vaping cannabis. Here is how the duration often compares based on the dose:

  • 2.5-5mg delta 9 THC – 4 to 6 hours
  • 5-10mg delta 9 THC – 6 to 8 hours  
  • 10-15mg delta 9 THC – 6 to 10 hours
  • 15-30mg delta 9 THC – 8 to 12 hours
  • 30-50mg+ delta 9 THC – 10 to 14 hours

As you see, higher THC doses lead to substantially longer effect duration given the slower metabolism of ingested THC by the liver into 11-hydroxy-THC. Consuming 50mg+ THC can lead to effects lasting up to 14 hours or more. With edibles, you are along for the ride once they kick in.

Onset delay

A major consideration with THC gummies is the delayed onset of effects compared to smoking or vaping cannabis. It takes 30 minutes to 2 full hours before you start feeling the gummy’s effects. This is because edibles must pass through the digestive system first before delta 9 THC enters the bloodstream and crosses the blood-brain barrier. Smoking and vaping provide rapid onset, but shorter overall duration. With edibles, be very patient when waiting for effects to start.

Effect plateaus

The long duration of delta 9 gummies is partly because once effects set in, they tend to plateau or level off for several hours rather than continuously increasing in intensity like with smoking. You may not feel drastically more stoned between hours 2-6 even though you are still very much high. The effects build slowly, peak, and then very gradually taper off. Be sure you have no important obligations for 8-12 hours after consuming higher THC dose gummies.

Metabolism and tolerance

Two big factors affecting THC gummy duration and intensity include your natural metabolism and tolerance level. Those with faster metabolisms may process THC faster, shortening the overall duration. Tolerance also plays a major role in effects. Those with high tolerance may only feel gummy effects for 6 hours while new users feel it for 10+ hours. Start low until you know your response. 

Strain and source

Certain cannabis strains and sources used to derive the delta 9 THC in gummies can also impact duration. For example, Sativa strains tend to provide more energizing, uplifting effects that last slightly shorter than couchlock indica strains. Delta 8 THC from hemp lasts shorter than weed-derived delta 9 THC. Know your source and strain effects.

Activities and environment 

What you do during the gummy experience also influences perceived duration. More active or social activities may make time pass quickly, so the effects seem shorter. Relaxing activities like watching movies make the high feel longer. Additionally, calm, familiar environments tend to make the effects more pleasant versus busy, chaotic settings. Consuming gummies on an empty stomach, with higher potency, lower tolerance, and minimal activities will produce the longest high. Use discretion when ingesting THC gummies if needing to function sober within several hours.
