Dosing, Onset & Metabolism
Duration
Duration is the length of time that cannabis effects last after they begin.
What Duration Means in Cannabis Use
In cannabis use, duration refers to how long the effects of cannabinoids (active compounds like THC and CBD) remain noticeable in the body after onset. Duration varies widely depending on the method of consumption, dose, individual metabolism, and the specific cannabinoids and terpenes involved. Understanding duration helps users plan experiences and avoid unintended impairment.
Historical Understanding of Duration
Historically, duration was most easily understood with smoked cannabis, where effects typically rise quickly and fade within a few hours. As edible and beverage products became more common in the modern legal market, duration became a more important concept because these products often last much longer and feel stronger than inhaled forms. This shift led to clearer consumer education and labeling standards beginning in the early 2000s.
Duration by Consumption Method
Different consumption methods produce distinct durations. Inhaled cannabis usually lasts 2–4 hours, with peak effects occurring within the first hour. Edibles can last 6–8 hours or longer because cannabinoids are processed through the digestive system and liver. During this process, THC is converted into 11-hydroxy-THC (a more potent and longer-lasting metabolite). Cannabis beverages often fall between inhalation and edibles, commonly lasting 3–6 hours, depending on formulation and dose.
How Duration Influences Product Design
In cannabis cultivation and product development, duration influences plant selection and formulation strategy. Growers may cultivate varieties with cannabinoid and terpene profiles that support shorter or longer effects. Manufacturers adjust dose size, cannabinoid ratios, and delivery systems to create products designed for daytime use, evening relaxation, or extended therapeutic relief.
Common Duration-Related Challenges
Common challenges related to duration include underestimating how long effects will last and combining multiple doses too close together. This can lead to prolonged intoxication or discomfort. A key guideline is to allow the full duration to pass before re-dosing, especially with edibles. Understanding duration allows for safer consumption, better scheduling, and a more controlled cannabis experience.
