Regular cardiovascular exercise can increase metabolism while also cleansing oxygenated blood through sweat. This can help flush out stored cannabinoids from adipose tissue faster. The frequency of cannabis use can have a large impact on how quickly how long does weed stay in your system THC gets processed and eliminated from your system.

Saliva tests
However, in general, when the primary psychoactive effects of cannabis (ie. the high) are over, things return to normal, despite lingering THC metabolites being released from fat cells for several days or weeks. Blood tests can detect THC metabolites for several days to a few weeks. Upon inhalation, active THC can be found in the bloodstream within seconds and detected in plasma for several hours, depending on the frequency of use and dosage.
While the type of marijuana that is consumed doesn’t affect the detox period, it does affect the duration of marijuana’s psychoactive effects.

They did detect THC in the hair of 77 percent of heavy cannabis users and 39 percent of light users. While the authors concluded hair analysis is appropriate for detecting marijuana consumption, they said the approach was unreliable for detecting light cannabis consumption. A 2009 study published in the journal Addiction tested THC blood concentration levels in 25 frequent, long-term cannabis users over seven days of abstinence. Sixteen users had at least one positive THC test during those seven days. Six users displayed positive THC levels on the final day of abstinence.

Factors Influencing How Long Weed Stays in Your System
The amount of THC consumed also significantly affects how long it stays in the system. Generally, the more THC that has been ingested, the longer its presence will be detectable. THC is stored in fat cells for a longer period with higher intake levels. Higher levels can remain active in the body for up to three months after consumption, while lower amounts usually pass within two weeks. In a 2009 study published in Addiction, researchers monitored cannabinoid concentrations in the blood of 25 frequent cannabis consumers. During seven days of abstinence from cannabis, nine subjects, or 36%, had no measurable THC in their system, while the other 16 still had at least one positive THC test over the same timeframe.
- It will take closer to 5.5 half-lives to filter out a drug completely.
