if i smoke once a week how long till i'm clean

If smoking cannabis once a week, THC and its metabolites are typically detectable in urine for around 7 to 10 days, but this can vary based on individual factors. Blood and saliva tests generally detect THC for a shorter time, about 1 to 3 days after use. Hair follicle tests have the longest detection window, up to 90 days. Factors such as metabolism, body fat percentage, frequency and amount of use, and overall health can influence these times. Occasional weekly smoking usually results in a clean system within about a week, but some people may test positive for slightly longer depending on these factors.
