The duration of cannabis effects varies significantly depending on the method of consumption, dose, THC content, and individual factors like metabolism and tolerance. Typical duration by consumption method:

• Smoking or vaping: Effects are felt within minutes (2-10 minutes) and usually last 1 to 3 hours, though they can linger up to 6-8 hours in some cases

• Edibles (eating or drinking cannabis): Effects take longer to kick in (30 minutes to 2 hours) but last much longer, typically 4 to 12 hours, and sometimes up to 24 hours

• Dabbing (highly concentrated cannabis): Effects are almost immediate and can last 1 to 3 hours or longer depending on THC concentration

Additional factors influencing duration:

• Higher doses and higher THC content generally prolong the effects

• Frequent users may develop tolerance, which can shorten the perceived duration and intensity of effects

• Beginners may experience longer-lasting effects, sometimes up to 15 hours, especially with edibles or high-THC products

In summary, the cannabis high generally lasts from about 1 to 6 hours for smoking/vaping, and from 4 to 12 hours or more for edibles, with some variability based on individual and product factors
