The effects of marijuana edibles begin within the first hour or so after consumption. They may be felt for up to eight hours.

The Timeline of Cannabis Edibles 

While many people smoke cannabis and are accustomed to feeling the effects of the drug right away, taking a marijuana edible is a longer, more drawn-out process.

First, you will begin to feel the effects of an edible from 30 to 60 minutes after taking it. The highest levels of THC in your blood are recorded between 1 to 3 hours after ingesting a marijuana edible.

The effects of edibles generally last from 6 to 8 hours, but this number can vary depending on a variety of factors.

Factors That Affect the Timeline

While some generalizations can be made, it is important to note that a multitude of factors may affect how long edibles stay in your system. How many milligrams of THC you consume is an important factor, but even with that benchmark, every individual is different.

Your height, age, and weight, as well as how often you ingest marijuana and if you have built up a tolerance, can all impact how long you feel the effects of an edible.

In addition to taking longer to kick in, edibles also remain in your system for a longer period of time when compared to marijuana that is smoked or inhaled.

Because the effects of marijuana edibles take longer to kick in, some people may be inclined to take a second dose after the first one. Given that the peak effects of edibles can take hours to reach, it is unwise to take another dose after your first, as you still may not be experiencing peak effects.

How Long Does THC From Edibles Remain in Your Body?

Traces of THC from edibles can remain in your body for far longer than the effects of a marijuana edible last. In fact, traces of THC can remain in your body for 90 days.

Different types of drug tests are used to detect the presence of cannabis in the body. Each type of test can detect the presence of THC for varying amounts of time.

  • Saliva: A saliva test can pick up traces of cannabis only a single day after an edible is last ingested.
  • Sweat: A sweat test can find cannabis in the body in between one to two weeks after an edible is last ingested.
  • Urine: Urine tests, which are one of the most common forms of drug testing, can detect cannabis remnants in the body from 1 to 30 days after an edible is last ingested.
  • Hair: THC remains in the hair for far longer than any other part of the body. As a result, it is detectable for a longer period of time in hair follicle tests. THC can be detected up to 90 days after an edible is last ingested via this type of drug test.
