We get this question often. There is no exact answer. It also depends on what you are talking about; urine testing, hair testing, oral fluid testing or blood testing. It also depends on many other factors including: how much THC has been used over what period of time, how much body fat someone has, exercise patterns, amount of water you drink, diet and other factors.<\/p>\n\n\n\n
You will get many different answers to the question, how long does marijuana stay in your system?<\/p>\n\n\n\n
Here are some approximate times:<\/p>\n\n\n\n
Urine Testing<\/a><\/strong>: Anywhere from 1 day to 30 days or more. It will take at least several hours for the THC to show up in your urine.<\/p>\n\n\n\n If you smoke rarely your urine may be clear of metabolites in less than 1 week and if you are a more frequent user, it could be anywhere between 3 and 30 days. Note that marijuana metabolites are stored in fat tissue so those users who are overweight will probably take longer to clear the drug.<\/p>\n\n\n\n Marijuana – Cannabinoids Detection Time:<\/p>\n\n\n\n \u00b7 Light smoker or acute dosage; 1-3 Days<\/p>\n\n\n\n \u00b7 Moderate Use (4 times\/week); 3-5 Days<\/p>\n\n\n\n \u00b7 Heavy Smoker (daily); 10-21+ Days<\/p>\n\n\n\n \u00b7 Heavy Chronic Use (5+ joints\/day); 10-30+ Days<\/p>\n\n\n\n \u00b7 Oral Ingestion, edibles; 1-5 Days<\/p>\n\n\n\n \u00b7 Chronic use over period of months or years; 4-6 weeks<\/p>\n\n\n\n Hair Testing<\/strong><\/a>: Up to 90 days, broken down by \u00bd inch of hair detects about 30 days. It will take about 7 days for the THC to show up in the hair.<\/p>\n\n\n\n Oral Fluid Testing<\/a>: 1 to 48 hours, the THC can show up in the oral fluid in as little as 1 hour.<\/p>\n\n\n\n
