Marijuana, also referred to informally as 'weed,' has been in use for a long time. The drug has been used for recreational purposes. The use of marijuana has been illegal in most countries in the world as a result of some of the negative effects associated with prolonged and heavy use. But there has been a major shift in the recent past with the introduction of medical marijuana. Some positive effects of the drug have been discovered, especially when taken in moderate amounts which have led to its legalization in some countries, albeit for medical purposes only. Many people have had an interest in finding out how long weed stays in the body system before its effects wear off completely. There have been many myths surrounding this particular subject. Marijuana affects people differently depending on more factors. And these factors are the ones that determine how long the drug stays in the system. Some of these factors are considered below.

 

Weight of the Body

The active ingredient in marijuana, tetrahydrocannabinol (THC), spreads throughout the body after being taken. The chemical takes time to be completely broken down and eliminated from the body system. The size of the body and, consequently, the weight of the body determines how fast or slow metabolism takes place. People who have fairly big body sizes normally experience slower metabolism as compared to lean people. This means that THC will stay longer in the body for such people as compared to their leaner counterparts.

 

Duration of Use

Well, just because you have smoked weed once or twice doesn't mean that it will take forever to clear from your body. There's a difference in the retention period between regular users and those who just smoke it once in a while. It has been found that for those who smoked weed just once, it takes about 2 - 5 days to clear, about 7 - 20 days for those who use it occasionally and between 20 t0 100 days for the frequent and heavy user.

 

Quantity of the Drug Taken

The quantity of the drug taken in a single session of smoking also determines how long marijuana's effects will last in the body. Larger and heavier doses of the drug definitely implies a longer retention period in the body. Here is also where the potency of the drug is considered as well. The most potent marijuana is normally derived from the seeds of the plant, and this stays longer in the bloodstream, even if only smaller quantities are taken.

 

State of the Liver

 

The function of the liver is to detoxify the body by breaking down harmful substances. THC is among those chemicals that end up in the liver for detoxification. A healthy liver means that the chemical will be eliminated faster whereas a liver impaired with disease will either be slow or totally incapable of getting rid of the drug.
