Here’s the number most people are after: a high from smoked or vaped flower usually lasts about two to four hours, peaks around the 10-to-30-minute mark, and tapers off after that, with a faint residual haze that can hang on for a few more. Eat it instead and the clock stretches a lot — edibles run four to eight hours or longer, sometimes with mild after-effects into the next morning. Dabs and other concentrates hit almost instantly and clear in the same two-to-four-hour window as flower, just harder. So there’s no single answer; the honest one is “it depends on how you take it, how much THC is in it, and who you are.” Below is the timing broken down by method, why a 36% quad feels different from a 22% value jar, and how to line all of it up so you’re not still floating when you needed to be functional. This is general product information for adults 19+, not medical advice.
Duration by method, side by side
The biggest lever on how long you feel it isn’t the strain — it’s the delivery method. Inhaling puts THC into your bloodstream through your lungs in seconds, so it arrives fast and leaves relatively fast. Eating it routes THC through your liver first, which converts it into a longer, heavier metabolite, so edibles are slow to start and slow to quit. Here’s the practical spread, drawn from public health sources including Health Canada and the general clinical consensus:
| How you take it | Starts working | Peaks | Main high lasts | Lingering effects |
|---|---|---|---|---|
| Smoked flower (joint, bowl, bong) | 1–5 minutes | 10–30 minutes | 2–4 hours | Up to ~6 hours for some |
| Vaped flower or cart | 1–5 minutes | 10–30 minutes | 2–4 hours | Similar to smoking |
| Dabs / concentrates | Seconds | Within minutes | 2–4 hours | Big doses can linger longer |
| Edibles (gummies, chocolate) | 30 min–2 hours | 2–4 hours | 4–8+ hours | Mild residual up to ~24 hours |
| Tinctures / oil under the tongue | 15–45 minutes | 1–2 hours | 3–6 hours | Gentler taper |
The single most common mistake — and the reason cannabis help lines get calls — is treating an edible like a joint. If nothing happens in fifteen minutes and you take a second dose, you’ve likely stacked two servings that both land an hour later at full strength. With anything you eat, the rule is take one, wait a full two hours, then reassess.
Why potency stretches the clock
Two people can smoke the same amount of flower and feel it for very different lengths of time, and THC percentage is a big part of why. More THC per puff means a stronger peak, and a stronger peak generally takes longer to come all the way down. That’s the practical case for knowing what tier you’re buying. On our menu the jump is real: everyday AAAA “quad” flower sits around 28–32% THC, the top Premium Craft gas cuts push to about 36%, and the honest value jars land in the low-to-mid 20s. A couple of draws off a 36% cut will feel more intense and hang around longer than the same two draws off a 22% jar — which, depending on your evening, might be exactly what you want or exactly what you don’t.
Here’s how a slice of the current in-stock flower lines up by strength, so you can see the range for yourself. THC figures come straight off the live listings:
| Strain | Tier | THC | What the duration feels like |
|---|---|---|---|
| King Louis OG | Premium Craft LSO Gas | 36% | Long, heavy peak — a little goes a long way and lasts |
| Death Cookies | Premium Craft LSO Gas | 36% | Big front-loaded hit that tapers slowly over a few hours |
| Blue Death Carnage | Premium AAAA Gas | 35% | Strong and durable; an evening’s worth from a modest amount |
| Master Craft Kush | AAAA Gas | 32% | Solid two-to-four-hour ride without the ceiling of the craft gas |
| Strawberry Blue | AAAA Sativa | 30% | Brighter, shorter-feeling head high — easier to shake off |
| OG Kush Breath | Premium Value | 29% | Middle-of-the-road length and intensity for daily use |
| Wedding Runtz | Mega Value | 24% | Shorter, lighter — a manageable one-to-two-hour session |
| Grand Daddy Purple Kush | Mega Value | 22% | The gentlest of the group; wears off soonest |
Notice the pattern: the strongest jar isn’t automatically the “best” one, it’s the longest and most intense one. If you want a short, tidy session you can walk away from, a value jar in the low 20s is the smarter buy. If you want a proper couch evening, the Premium AAAA and craft gas do that — with the caveat that you dose accordingly.
The parts of the high nobody warns you about
Beyond method and potency, the duration you personally get comes down to a handful of body factors. Dose is the obvious one — more THC, longer high. Tolerance cuts the other way: a daily smoker often clears a high faster than someone who partakes twice a year, even off identical flower. Metabolism and body composition matter too, because THC is fat-soluble and lingers longer in some bodies than others. And an empty stomach tends to make an edible hit faster and harder than a full one. None of these are things you can change on the fly, but knowing them explains why your high and your friend’s high off the same joint end at different times.
What a high actually feels like from start to finish
If you map an inhaled high, it moves through a rough arc. The first ten to thirty minutes is the climb — effects building, senses sharpening. The next thirty to ninety minutes is the peak, where it’s strongest. From there it’s a gradual comedown over one to three hours as things level out, often into a mellow, slightly sleepy tail end sometimes called the afterglow, which can drift on well past the “official” high. Edibles run the same shape stretched across a much longer timeline. Knowing the arc is useful mainly for pacing: if you’ve got somewhere to be, count backwards from when you need to be clear, not forward from your first puff.
Riding out a high that’s too strong — and the next morning
Sometimes a high lasts longer or hits harder than you bargained for, usually from an edible or an unexpectedly potent cut. It isn’t dangerous, but it can be genuinely unpleasant — racing heart, anxiety, the feeling that it won’t end. The move is simple: find a calm spot, hydrate, have a snack, and remember it will pass on its own within a few hours. Nothing makes THC leave faster, so the goal is comfort and patience, not a cure. As for the morning after, a heavy session — edibles especially — can leave some people foggy or tired the next day, much like a mild hangover. Keeping the dose reasonable is the single best way to avoid both an overshoot and next-day grogginess. If effects ever feel severe or don’t settle, treat it like any other health concern and reach out to a medical professional; none of this is medical advice.
Timing it around same-day delivery
The practical upshot for planning: because inhaled flower comes and goes inside a few hours, it’s easy to fit around your evening, while edibles need a runway you should respect. If you’re ordering for tonight, same-day delivery across Toronto and out through Mississauga, Vaughan and Hamilton means you can decide in the afternoon and have the jar in hand before you actually want to use it — no need to over-buy or rush the dose. Every order is adults-only with ID checked at the door, and the strongest small-batch gas moves fast, so if a specific strain in the tables above is the one you’re after, it’s worth grabbing while it’s listed. Pick your method for the length of high you want, match the potency to that, and the timing takes care of itself.
Quick answers on how long a high lasts
How long does it take for a weed high to wear off?
From smoking or vaping, most of the high is gone within two to four hours, with faint residual effects fading over a few more. Edibles take longer to clear — commonly four to eight hours. Dose, tolerance and your metabolism all shift the exact time.
How long after smoking do you feel high?
Fast — usually within one to five minutes, because inhaled THC reaches your bloodstream through your lungs almost immediately. It builds to a peak around ten to thirty minutes in. That speed is exactly why smoking is easier to pace than edibles, which can take up to two hours to arrive.
What are the stages of a cannabis high?
Roughly four: the climb as effects build over the first 10–30 minutes, the peak where it’s strongest, a comedown over one to three hours, and a mellow afterglow that can linger past the main high. Edibles follow the same shape across a longer timeline.
Does weed make you tired the next day?
It can, especially after a heavy session or an edible taken late. Some people wake up foggy or groggy, a bit like a mild hangover. Keeping the dose modest and not dosing too close to bedtime usually keeps the next morning clear. Everyone reacts differently.
What should you do if you get too high?
Stay calm, sit or lie down somewhere comfortable, drink water and have a light snack. It always passes on its own within a few hours — nothing speeds THC out of your system. Next time, take less and wait longer before redosing. If symptoms feel severe, contact a medical professional.
