How Long Does an Edible Last?
If there's one piece of cannabis information that would prevent the majority of difficult first experiences, it's this: edibles take a long time to kick in, and when they do, they last a long time. Understanding the timeline before you start is everything.
The edible timeline
Here's what a typical edible experience looks like:
0–30 minutes: You feel nothing. This is normal.
30–90 minutes: Onset begins for most people. You may start to notice mild effects.
90–120 minutes: Peak effects for many people. This is when the full experience arrives.
2–6 hours: Duration of the experience at moderate doses.
Up to 8+ hours: At higher doses, effects can persist significantly longer.
This timeline varies based on your metabolism, whether you've eaten recently, the type of edible, and your body's individual response. But the key number to remember is two hours — that's your minimum wait time before considering any additional dose.
Why do edibles take so long?
When you eat a cannabis edible, the THC has to travel through your digestive system before it enters your bloodstream. It's absorbed in your intestines and then processed by your liver, which converts THC into a compound called 11-hydroxy-THC. This metabolite is actually more potent and longer-lasting than THC itself — which is part of why edibles feel different from, and often more intense than, inhaled cannabis.
Compare this to smoking or vaporizing, where THC reaches your bloodstream within minutes through your lungs.
Why the experience feels different
Because of that liver conversion, edibles often produce a more body-centred, longer-lasting experience. Many people describe edibles as feeling "heavier" or more sedating than inhaled cannabis at comparable THC doses.
This is also why 5mg of edible THC and 5mg of inhaled THC are not the same experience — even though the number is the same.
How to have a good edible experience
Start with 2.5–5mg for your first time
Take it on a partially full stomach (empty stomach = faster, more intense onset; full stomach = slower, gentler)
Set a two-hour timer before you consider more
Plan your schedule — you may feel effects for 4–6 hours
Have water and a comfortable place to be
Mary Jane says: "Edibles are not impatient. And they reward people who aren't either. Set your timer, put the package away, and let the experience find you."
If you took too much
You're going to be fine. Lie down somewhere comfortable, breathe slowly, and remind yourself that what you're feeling is temporary. It will pass. Having CBD on hand may help take the edge off. If you feel genuinely unwell, it's always okay to seek help.
