The Onset: When You'll Start Feeling The Effects Of THC Gummies

Ever wondered how long it takes for marijuana gummies to work their magic? The answer can vary, but generally, THC gummies take about 30 minutes to an hour to kick in. This is due to the fact that they need to be digested and absorbed by your body before you start feeling their effects. 

It’s important to note that the onset time of marijuana gummies can be influenced by factors such as:

  1. your metabolism

  2. the type of cannabis gummies you consume

  3. eating a THC gummy on a full stomach vs. an empty stomach

So, it’s always best to start with a low dose, give it some time to assess your high, and never take another serving unless 2 hours have passed.

The Duration: How Long The Effects of Weed Gummies Will Last

Several factors come into play when it comes to the duration of THC gummies’ high effects. These factors include the individual’s metabolism, tolerance, and the potency of the gummies.

According to MedicalNewsToday.com, the duration of effects can last anywhere from 4 to 12 hours, depending on the dosage and individual tolerance, with the peak effects occurring around 2 to 3 hours after consumption. 

  1. Metabolism: Individuals with faster metabolic rates may process THC more quickly, leading to shorter effects. On the other hand, those with slower metabolisms may experience a longer-lasting high. 

  2. Tolerance: Frequent cannabis users may have a higher tolerance to THC, resulting in a less intense and shorter-lasting high. The effects might last longer and feel more potent for those with a lower tolerance. 

  3. Potency: The strength of the Delta-9 gummies also plays a significant role in determining how long the effects will last. Higher potency gummies will produce stronger and longer-lasting effects compared to those with lower THC concentrations.
