Whether you’re new to cannabis (or returning after a long absence), there’s one question you’ll want to get answered first: How long does a weed high last? Or, if you’ve already indulged, you might get as far as typing “how long weed high last?” and then collapse in a fit of giggles.

In all seriousness, the answer—as you might expect—depends on a number of variables. In today’s post, we’ll share everything we know, with the goal of empowering you to make better-informed and more objective decisions about your cannabis use.

How Long Does a Weed High Last? The Basics

Before we—erm—get into the weeds, we’ll make it easy with the average: A weed high usually lasts about one to three hours.

As we hinted a moment ago, though, there’s more to the story. The major difference involves the choice of delivery method. For instance, the high from smoked or vaped cannabis generally doesn’t last as long as that from edibles or tinctures. What’s more, the onset time—the time it takes for you to actually begin feeling the effects—will be quite different.

With that in mind, here’s an introductory guide to the major delivery methods.

Flower and Vapes

For many people, flower is still the most familiar form of cannabis. While there are important differences between consuming cannabis by inhaling burned flower or with a purpose-made vape, they’re similar in one key way: Their effects come on more quickly (and fade more quickly) than other forms of cannabis.

Cannabis Onset Time for Flower and Vapes: 1 – 10 minutes

Duration of Effect for Flower and Vapes: 1 – 6 hours

Tinctures take longer to go into effect than flower—sometimes up to two hours. For a faster onset, try putting the tincture under your tongue and holding it there for a minute or two. If you use this “sublingual” method, you can likely expect to feel the effects in anywhere from 15 to 45 minutes. What’s more, because the tincture doesn’t come into contact with your stomach acids, it’s believed that this allows our bodies to make more complete use of all the beneficial compounds and chemicals in the tincture.

Cannabis Onset Times for Tinctures: 15 minutes – 2 hours, depending on route of administration (under tongue or swallowed)

Duration of Effect for Tinctures: 4 – 12 hours

This exciting form of cannabis includes foods, candies, and beverages infused with cannabis. Although the cannabis medicine they contain functions in a similar way as tinctures, it’s especially important to pay attention to dosage and portion size so you don’t end up taking more than you intended to. (Believe us, it happens more often than you might think.)

That’s why we always advise our customers to read the label carefully. Is the edible a chocolate bar meant to be broken off into much smaller portions, for instance? Is a bottle of cannabis-infused tea meant to serve a single person, or several? On a related note: Be sure to keep any cannabis-infused foods away from children, who may not understand the written warning on the packaging!

Cannabis Onset Times for Edibles: 1 – 3 hours

Duration of Effect for Edibles: 4 – 12 hours

As we’ve said time and time again, plan to wait at least two hours for the full effects of edibles to become apparent!
