It could awhile. If you take the hits off a J or a bong, be sure to drink plenty of liquids after ( grapefruit juice). Or just pee before you smoke and keep that in a bottle if you plan on doing a urine drug test.
Marijuana isn't measured in "hits". Be more specific.
15 days.
Four hits in one hour
Forever.
Smoking marijuana introduces a chemical called Tetrahydrocannabinol (THC) into your system. Because THC is stored in the fat cells, it generally takes anywhere from 30 - 40 days to leave your system.
Less than a month. Smoking more often than that stays in your system for 30 days, so 6 hits is nothing.
The chemical found in marijuana can remain in your system for up to 30 days.
Marijuana stays in your system for about 48 hours.
I heard that if you drink 8 Monster Energy drinks that it cleans your system. You can also drink a lot of water to flush your system out. But if you are so worried about getting caught with THC in your system maybe you should look into different activities to save yourself the trouble.
Years??? Marijuana stays in your sysytem for 1-60 days depending on how much you smoked and how strong the marijuana was. The 4 hits that you took was out of you system in a couple days.
The traces of marijuana found in urine samples are stored in fat cells. So depending how much fat you have and also depending on how much you workout and sweat the toxins depends on how long it will take to flush. Also drink lots of water to flush your system. Taking condensed cranberry pills such as AZO's also helps flush your system.
In about three hours it should be gone and you should be feeling much better.
