how long does cannabis stay in your blood for?

Answer 1

depends on how long u smoked it... usually around 6 weeks though if you smoked heavily can be 2 months (also depends on how fat you are as it gets stored in the body's fat and released after exercise- thats why you may feel stoned again after running).. though it stays in hair faarrr longer (6 weeks odd+ when it's cut out)

Answer 2

How long does cannabis stay in the system
Q - Can you tell me how long does the cannabis drug stay in the system

A - How long drugs are detectable in the system depends on a number of factors:

15-30 days
The drug taken

How much and how often taken

Body weight

Individual metabolism

Sensitivity of testing used

Body fluid/tissue used (blood, plasma, urine, saliva, sweat, hair)

Other substances taken (e.g. dilution of urine sample, masking agents or adulterants)

Most urine tests are simple colour-change screening devices, which can react positively to other inactive substances, and should always be confirmed with a detailed GCMS forensic analysis (Gas Chromatography-Mass Spectrometry).

A single hit of cannabis may disappear in a few days, whereas heavy or chronic use can be detected in urine up to a month after stopping. Amphetamine is detectable for up to a week.

A low level of cannabinoids in urine can readily be produced from passive exposure to cannabis smoke, from being in a room, car, bar, concert etc with others who are using. If a responsible test is used, there should be a cut-off level below which a negative result would result, to avoid 'false' positives from passive exposure. The more sensitive the test, the greater the number of false positives, and the longer period for detecting drugs in urine after the last use.

One way to minimise the risk of a positive result is to avoid giving a sample from the first pee of the day, and to maximise the volume of urine produced e.g. by drinking plenty of water or coffee (caffeine is a diuretic) before the test. Several websites offer various products claimed to beat the drug tests, but I am unaware of any which are effective every time.

Answer 3

Depends on how much and how long you have been using it. You can confuse the results of a test by t aking ibuprofen which gives a false negative. As far as I am aware, moderate use is liikely to stay in your blood for anything from seven days to a month. A heavy user may have it in their blood for up to three months.

Answer 4

30 days

Answer 5

30 days

Answer 6

30 - 60 days depending on your daily consumption

Many drug tests now use a hair sample. They don't tell you that before you show up either! The hair folicles maintain a drug history and never decay off.

Good Luck!

Answer 7

Depend on the potency, frequency, and method of use. Sometimes THC can be detected in a user for over a month after abstaining in drug tests.

Answer 8

If your in the forces and smoking dope then I hope you are aware of the consequences and also the psycological effects cannabis can have ............... ie paranoia/reduces brain function ........... it stays in your blood/urine for a couple of weeks..........solution = dont smoke it/eat it,

Answer 9

28 days. Can stay in hair for longer. Depends on how much you take it and how long your hair is, also how often you cut it as well.

Answer 10

Depends.........it it's your first time a couple of days
if you do it on occasion say once a weekend it will take about 5-7 days
...........and if you do it every day or for every meal well it could last from a week to a week and a half. Don't believe that 2-3 weeks bull crap, it's just a scare.
BUT.......if you drink tons of water and keep pissing then you can knock off a couple of days.
