Among the everlasting questions in marijuana culture has lastly been answered by science: After using cannabis, how long will you remain high?

I was reading a post on Leafly that sparked my interest. For the first time, I see a study about how long will a marijuana high last.

In a 2021 study published in Neuroscience & Biobehavioral Reviews, a team of researchers led by Danielle McCartney of the University of Sydney identified a “window of impairment” that lasts somewhere between 3 to 10 hours, depending upon the THC dosage, the mode of consumption, and the customer's previous cannabis experience.

Those are a lot of factors, but the TL; DR is: usually, four hours.

The intoxicating high from a lighter inhaled dosage will typically last for three hours, while a deep dabbing session or heavy edible may continue pinching hit 6 to 10 hours.

Collecting information from 80 studies

McCartney and her coworkers undertook a detailed analysis of 80 clinical studies on marijuana dosage and intoxication.

Since the focus of their research study was on the effect of cannabis intoxication on driving skills and awareness, much of the work was manipulated toward answering those questions.

The researchers discovered that marijuana consumers recuperated most of their driving-related abilities within 5 hours of inhaling 20mg of THC. Customers who consumed the same amount of

THC through an edible took longer to recuperate their driving skills. A lot of marijuana edibles in legal markets are dosed at 10mg per serving, and 100mg overall THC per package.

” Overall, our results validate that Δ9-THC impairs aspects of driving efficiency,” the scientists wrote. “There appears to be no universal answer to the question of How long to wait before driving? following cannabis use: Consideration of multiple factors is therefore required to determine appropriate delays between Δ9-THC use and the performance of safety-sensitive tasks.”

Edible highs strike later and last longer

The distinctions between inhaled THC and consumed THC (by means of edibles) were substantial. It's widely known that the impacts of THC and other cannabinoids will be felt within minutes by customers who smoke or vape marijuana items, while an edible or drink can take up to an hour or more to strike.

In their review of the clinical literature, McCartney and colleagues discovered that the envigorating impacts of beverages and edibles usually last much longer than breathed in items.

Those researchers discovered that smoking or vaping 20mg of THC decreased a chauffeur's reaction time for roughly 4 hours. However ingesting 20mg of THC through an edible or drink lessened reaction time for 8 hours, twice as long. The study's data suggested a THC-impaired motorist's reaction time was diminished at a not remarkable but significant level.

Heavy edible? Could be a 10-hour trip

” Our analysis indicates that impairment may last up to 10 hours if high doses of THC are consumed orally,” stated McCartney, who works with the Australian university's Lambert Initiative for Cannabinoid Therapeutics. “A more typical duration of impairment, however, is four hours, when lower doses of THC are consumed via smoking or vaporization and simpler tasks are undertaken.”

The “Hit”– which cannabis users may experience as feeling high, or stoned, or deeply relaxed, or sleepy, or mirthful, or creative” “may extend up to six or seven hours if higher doses of THC are inhaled and complex tasks, such as driving, are assessed,” McCartney added.

For the purposes of this study, McCartney and associates thought about 10mg of THC to be a moderate dose. However a moderate dosage for a routine consumer, they included, could be a high dosage for an occasional one.

Routine users reveal fewer effects

As numerous marijuana consumers understand, regular use can result in the mind and body building up a tolerance for cannabinoids ingested from sources outside the body, such as weed. This was likewise verified by the University of Sydney researchers.

Co-author Dr. Thomas Arkell, likewise from the Lambert Initiative, said: “We discovered that impairment is much more predictable in occasional cannabis users than regular cannabis users. Heavy users show significant tolerance to the effects of cannabis on driving and cognitive function, while typically displaying some impairment.”

The scientists found that marijuana consumers recovered many of their driving-related skills within five hours of breathing in 20mg of THC. Consumers who consumed the same quantity of THC by means of an edible took longer to recover their driving skills. A lot of marijuana edibles in legal markets are dosed at 10mg per serving, and 100mg overall THC per bundle.

Those scientists found that smoking or vaping 20mg of THC diminished a driver's response time for roughly four hours. Ingesting 20mg of THC via an edible or beverage decreased response time for eight hours, two times as long.
