Like alcohol, there are a variety of factors which goes into how long it can stay in your system. Alcohol can stay in your system from 12-48 hours. Edible marijuana products can stay in your system longer due to the way they’re metabolized. A 10mg THC edible can remain detectable for 4-12 hours, with higher doses potentially extending this timeframe.
The variables influence how long marijuana remains in your system include:
Frequency of Use: Chronic users retain THC longer than occasional users. First-time users may clear THC in about 3 days, while daily users could test positive for up to 30 days or more.
THC Concentration: Higher potency marijuana leads to longer retention and slower elimination.
Body Composition: THC is fat-soluble, so individuals with higher body fat percentages may retain it longer.
Metabolism: A faster metabolism tends to eliminate THC more quickly.
