How Long Do The Effects Of Weed Take To Wear Off?

Last Updated

The effects of weed, whether you’re smoking cannabis, vaping cannabis, or consuming cannabis edibles, is a fascinating journey into altered states of consciousness. From the rapid onset of cannabis to the sedative effects that bring pain relief and increased appetite and blood pressure, the duration and intensity of these psychoactive effects vary depending on numerous factors.

Some may feel the effects of smoking marijuana within one to two minutes, while others using edibles may wait a couple of hours to experience the weed fully. In this blog post, we’ll explore the different factors that affect how long the effects of weed last, taming THC’s potential cannabis synergy with body weight, THC tolerance, and more.

We’ll also explore the possible cannabis effects on mental health and why young people may be at a higher risk, shedding light on the complex interplay of weed, brain, and body.

How Long Does a Weed High Last?

A cannabis high can last anywhere from 1 to 6 hours. The effects of smoking cannabis or vaping cannabis tend to have a quick onset, peaking within the first hour or so. On the other hand, consuming cannabis edibles may take longer for the weed to kick in due to the digestive system’s processing time, but it can result in a longer high.

Factors that affect the length of your high include the THC content in the product, your tolerance, body weight, consumption method, and how much THC you’ve ingested.

How Long Do Short-term Effects Last?

The short-term effects of weed, also known as the weed high, typically last for two to three hours. These effects can vary depending on factors like the THC content in the cannabis product, the consumption method (smoking cannabis, vaping, or consuming edibles), and the individual’s tolerance.

Smoking or vaping weed often results in a quicker onset of the weed high, with peak effects occurring within 3 hours.

On the other hand, consuming edible cannabis may lead to a slower start, but the results can persist for a few hours. Higher doses and marijuana products with high THC percentages may extend the duration of the short-term effects.

How Long Do Cognitive Effects Last?

The cognitive effects of marijuana can last for an extended period, ranging from two to four weeks. These effects can significantly impact an individual’s mental health and cognitive function.

Factors like the THC content, consumption method, and the amount of cannabis used can affect the duration of these cognitive effects. While the weed high typically lasts for one to six hours, the mental effects may persist long after the high has worn off.

How Long Do Long-term Effects Last?

The long-term effects of weed use can extend beyond a week, and various factors can influence their duration. These effects may involve changes in THC tolerance, particularly with regular and high-dose use of marijuana.

According to “An Evidence Based Review of Acute and Long-Term Effects of Cannabis Use on Executive Cognitive Functions by Rebecca D. Crean” Chronic cannabis use can affect cognitive functions, memory, and motivation, potentially lasting for weeks after the last use.

Moreover, individuals with a predisposition to mental health issues may be at a higher risk of experiencing long-term effects. Marijuana affects the brain’s cannabinoid receptors, which play a role in various psychological and physical processes.

What Factors Affect How Long a Weed High Lasts?

What Factors Affect How Long a Weed High Lasts?

There are five key factors are given below:

1. THC Content

The level of THC in the cannabis product is a significant factor. Higher THC percentages often lead to a longer-lasting weed high.

2. Consumption Method

Whether you’re smoking cannabis, vaping it, or consuming edibles can impact the onset and duration of the high. Smoking or vaping generally results in quicker effects, while edibles may take longer to kick in.

3. Individual Tolerance

A person’s tolerance to THC varies, and frequent cannabis use can affect this. Those with higher tolerance may experience shorter highs.

4. Body Weight

Your body weight can influence how long the effects last. Cannabis are stored in fat cells, potentially extending the duration for individuals with more body fat.

5. Cannabis Products

Different cannabis products, such as high-THC concentrates or regular flowers, can lead to varying durations of the weed high.

How Long Does It Take to Kick in Cannabis?

Cannabis takes between 30 seconds to two minutes for the high to kick in after consumption. This quick onset is due to the way THC, the primary psychoactive compound in weed, enters the bloodstream when inhaled.

When smoking or vaping, THC is absorbed directly through the lungs and quickly delivered to the brain, resulting in the cannabis high.

How to Reduce the Effect

Stay hydrated with water, as it can help alleviate some of the physical effects of weed. Additionally, consuming foods high in pinene, such as pine nuts or black pepper, may help counteract the psychoactive effects and provide a sense of calm.

Engaging in physical activities can also assist in taming THC and decreasing the duration of the high. Moreover, keeping yourself distracted and occupied can shift your focus away from the marijuana high. If you’ve smoked or vaped cannabis, getting some fresh air and deep breathing is beneficial.


How Long Does It Take for Your Body to Absorb Weed?

Your body typically absorbs weed within a relatively short timeframe, usually 3 to 10 minutes. This quick absorption occurs primarily when you are smoking cannabis or vaping it. The reason for this quick onset is that when you inhale weed smoke or vapour, the THC, the active compound in cannabis, enters your bloodstream through the lungs, allowing it to reach your brain and other parts of your body swiftly. The speed of absorption is influenced by factors like the potency of the cannabis, your inhalation technique, and your lung health.

Can Tolerance Impact How Long the Effects Last?

Can Tolerance Impact How Long the Effects Last?

When an individual develops tolerance to marijuana, the high typically does not last as long as it would for someone with lower or no patience. Over time, frequent and higher-dose cannabis use can lead to the body becoming less responsive to the effects of THC, the primary psychoactive compound in cannabis. As a result, the duration of the weed high may shorten, and individuals with tolerance may require more cannabis to achieve the same level of effects they previously experienced.

What Can I Do to Speed Up the Recovery Process?

To speed up the recovery process after cannabis use, staying hydrated and getting physical activity can help. Drinking water helps flush THC from your system, and light exercise can assist in metabolizing THC more quickly. Fresh air and a calm environment can also make recovery more comfortable.

The recreational use of cannabis is legal in Canada. In 2018, Canada became one of the first countries to fully legalize the use of cannabis for both medical and recreational purposes. This landmark decision allows adults in Canada to possess and use weed within the limits set by the federal and provincial governments.

Final Thoughts

The duration of the effects of weed varies depending on multiple factors. The results of cannabis can last anywhere from several hours. The specific period is influenced by factors such as the THC content, consumption method (smoking, vaping, or consuming edibles), individual tolerance, and the amount consumed.

Smoking or vaping cannabis often results in a more rapid onset, with effects peaking within 10 minutes and gradually tapering off. On the other hand, cannabis edibles may take longer to kick in but can result in effects lasting for 3 hours. Higher doses and weed products with high THC percentages can lead to longer-lasting effects.
