You’ve had a few gummies, maybe hit the vape—now you’re wondering, How long will this last? Whether you're a casual user or a regular, understanding how long cannabis impairment lingers can be tricky. You’ve probably heard wildly different answers, but thanks to new research, we now have some solid science to back up how long you’ll stay “elevated.”
Knowing the duration of impairment is key—not just for your safety but for planning your day. Can you drive after a gummy? How long until you're sharp enough for that Zoom meeting? Let’s explore what happens after you consume cannabis, how it impacts your performance, and how to stay safe and responsible.
Cannabis Isn’t One-Size-Fits-All: Why the Effects Vary
Cannabis affects everyone differently, and how long you’ll feel the effects depends on several major factors, including your physiology:
Consumption Method: Edibles, like gummies, have a much longer-lasting impact than vaping or smoking.
Strength of Dose: Higher-THC products will keep you impaired longer.
Tolerance Level: Regular users tend to bounce back quicker than occasional consumers.
Physical Condition and Metabolism: How your body processes cannabis can vary based on your metabolism, liver enzyme activity, diet, and digestive health.
These factors can mean the difference between feeling relaxed for a few hours or experiencing effects for almost half a day.
Edibles vs. Inhalation: Why the Method Matters
If you're an edible fan, such as someone who enjoys our cannabis-infused chocolate slabs or gummies, you’re in for a longer ride. Unlike inhaled cannabis, which enters the bloodstream quickly through the lungs, edibles are processed through the digestive tract and liver. This liver processing produces 11-hydroxy-THC, a stronger and more sedative compound than THC in its original form. As a result, the effects of edibles can last up to 10 hours depending on dose, metabolism, and physical health.
For inhaled cannabis, the effects come on much faster but also fade quicker. Cannabinoids absorb almost immediately through the lungs, entering the bloodstream and reaching the brain rapidly. Most users will feel back to normal after 4–6 hours, though it may take up to 6–7 hours before being ready for tasks that demand full concentration.
THC and its metabolites are primarily stored in fat tissue but can also be detected in blood, urine, saliva, and hair, with detection times varying based on frequency of use, body fat percentage, and consumption method. THC can remain detectable for:
Fat tissue: Up to 3 months in heavy users.
Blood: 1-2 days for occasional users; up to 7+ days in frequent users.
Urine: 3-4 days for occasional users; up to 30 days or more in heavy users.
Saliva: 1-3 days in occasional users; up to a week in frequent users.
Hair: Up to 90 days or longer.
Finding Your Active Dose
Knowing your “active dose” can help you control the intensity and duration of your experience. This refers to the smallest amount of cannabis needed to feel your desired effects, and it varies based on tolerance, metabolism, and experience. If you’re new to cannabis or trying edibles for the first time, experts recommend a conservative approach:
Start with a “microdose” of 1–2.5 mg THC, especially with edibles. Wait a minimum of 2–3 hours before consuming more.
For those with more experience, a 5 mg dose is standard, while higher doses like 15–30 mg may suit regular users.
If edibles are your preference, avoid the temptation to take more before the first dose kicks in. Delayed onset often leads to "stacking" doses, which can result in unexpectedly strong, long-lasting effects. To keep your experience enjoyable and manageable, always start low and give your initial dose time to work.
What Does a “High Dose” Really Mean?
When we say “high dose,” we’re talking about products with a significant concentration of THC. For example, consuming a potent edible with a heavy THC content could impair you for 8–12 hours. Frequent high-THC consumption, especially with edibles, may also increase your tolerance over time, meaning you’ll need more to achieve the same effects.
Regular inhalers may need even higher edible doses to feel the same impact due to the differences in how these forms of cannabis metabolize. A cannabis flower (1 gram) often has 150–250 mg of THC, which delivers a fast onset when smoked or vaped, but you would need roughly 80–150 mg of THC via edibles for similar intensity because of slower, more potent liver processing.
For newcomers or those aiming for a lighter experience, consider products like our CannaPop 25 mg x 4 gummies. Smaller doses are easier to control, making them ideal for those seeking a manageable high without the prolonged impairment.
Tolerance: Regular Users vs. Occasional Consumers
If you’re a regular cannabis user, your tolerance level can influence how long impairment lasts. Regular users often bounce back faster, meaning they require higher doses to achieve similar intoxication levels. However, even for frequent users, high doses can impact tasks requiring focus, like driving or operating machinery.
For occasional users, even a small dose can lead to a longer-lasting impairment, making it crucial to wait for full effects to wear off before engaging in activities requiring sharp mental or physical focus.
Cannabis and Driving: How Long Should You Wait?
While THC can stay in your system for days, impairment only lasts a fraction of that time. Most driving skills return within five hours of inhaling cannabis, but this varies based on the dose and consumption method. For strong edibles, it’s wise to wait longer.
As cannabis legalisation spreads, the conversation around drug-impaired driving is evolving. Experts agree that laws should focus on actual impairment, not just THC presence. Testing positive for THC days after use doesn’t mean impairment, which is why some regions are pushing for evidence-based regulations that reflect real-world usage.
Tips for Responsible Consumption
Whether you're enjoying our CBD-infused teas, a piece of milk chocolate, or a CBD + inhaler, responsible cannabis use involves understanding how long effects can last. Here are some tips to help:
Know Your Method: Edibles last longer than smoking or vaping, so plan accordingly.
Start Small: Especially if you're new to cannabis, start with a low dose, like our 5 mg gummies, and wait before taking more.
Be Patient: Don’t assume you’re ready to drive after a few hours; wait at least 6 hours after inhaling, and longer for edibles.
Mind Your Tolerance: Take occasional breaks if you notice you need more to feel the same effects. This can prevent excessive tolerance buildup.
The Bottom Line: Understanding Cannabis Impairment
Cannabis can be a versatile and enjoyable plant, whether used for relaxation, creativity, or stress relief. Understanding how long its effects last is essential for responsible use. Whether you prefer gummies, teas, or vapes, knowing your limits and planning ahead will help you maximise enjoyment without compromising safety.
