If you’ve smoked or vaped weed, the shakes shouldn’t usually last longer than 30 minutes. However, if you’ve ingested edibles, the shaking may persist for a few hours.
The dose you’ve consumed is a factor too–larger doses of weed, or more THC-concentrated cultivars, may result in a longer time trembling. This is all likely dictated by the THC levels in the body, so this timerame can only be considered an estimate because of the metabolic variabilities between individuals.
