How Long Drugs Stay in Your System

The following are estimated times different drugs will remain present within your body. All times are estimates and we recommend drug testing yourself if you suspect you might test positive for drugs.

How Long Marijuana Stays in System

Taken from How Long Does Marijuana Stay in Your System.com

amount of marijuana used

A first time pot user, will have weed detectable in the body for a period up to 7 days. A casual marijuana smoker (2-3 times a week); thc can be detectable for a period up to 21 days. Chronic weed smokers can expect to test positive for thc toxins for up to 90 days.

Other factors to consider when figuring out how long marijuana will remain in your body are:

metabolic rate

A metabolic rate is the rate at which a person's body run. A person with a faster metabolic rate will have a shorter detectable time for thc than a person with a slower rate. This being said, a person who smoked pot recently and has a fast metabolic rate will excrete larger amounts of thc than a person with a slower metabolic rate. The metabolic rate ties in with the next factor in determining how long marijuana stays in your system:

body fat percentage

Body fate percentage is critical to determine how long thc will stay in your system. THC is stored in the fat cells in your body. So the more fat cells that you have the more storage space you have for marijuana.


How Long Cocaine Stay in System

Taken from How Long Does Cocaine Stay in Your System
“Benzoylecgonine” is a metabolite which is produced after the ingestion of cocaine. Benzoylecgonine is different from marijuana with regard that Benzoylecgonine is water soluble. Which means cocaine is passed though the body much more quickly than weed.

A person’s body mass index or BMI, (body fat percentage), is a big factor to consider when figuring out how long cocaine and its metabolites stay in our system. The higher a person's BMI the longer cocaine will remain in present in urine.

The frequency of cocaine use and the potency of the cocaine are the next major factors to consider when calculating how long does cocaine stays in your system. A person who uses cocaine on a daily basis is going to have more cocaine metabolites than someone who uses cocaine less frequently.

These are the major factors which contribute to how long cocaine stays in your system. We can predict how long the body will continue to show evidence of cocaine usage. It has been suggested that evidence of cocaine usage can be detected by drug testing for up to 5 days in most instances. This time frame is not accurate in many cases. Some people can show evidence of cocaine usage for periods of time far greater than 5 days, in some rare cases up to 30 days.
