Are you a user of marijuana, related drugs or any other drug for that matter? If the answer is ?yes?, then be on your guard! Do you know how long the signs of this weed will remain in your system? Read on; there is some news for you! 

When you use marijuana in the form of smoke or swallow, it the body breaks it down and metabolizes. The harmful chemical tetrahydrocannabinol or THC is separated. This THC is passed into the blood stream and stored in the fat of the body. It does not go away immediately. It slowly goes out of the body along with urine, sweet and saliva. THC is not soluble in water. So it does not go out of the body with these excretions very fast. THC is fat soluble. So fat in the body holds it for a long period.  

If you smoke marijuana or use any other related drug once, it will take three to four days for your body to throw the weed out of your system, provided of course, you do not smoke a second time during the interim period. If you decide to have another go at the drug a second time within two days of the first, the body will take about a week to discard effects from it after the last use. Every subsequent use within the stipulated period will double the time required to wash the weed off your body. For a frequent user it will take up to forty five days. Since the THC is fat soluble a fat body can store more of the chemical than a lean body. So a fatty addict may take up to sixty days to discard the weed in it. 

If you want to cheat at a drug test you will not find any success, if the time mentioned above has not expired. Some users are of the belief that in a blood test the traces of the weed will disappear with their urine if they drink plenty of water. That does not happen because THC is not water-soluble. Any quantity of water will not help. Water cannot wash it off. Only time can help you in a blood test. For a casual user a blood test will show ?positive? if the test is taken within four days of use. For a regular user the time required is about seven weeks.  

In the case of a urine test a casual user can be detected within seven days of the use. But for a regular user the weed can be detected up to thirty days. The blood test gives a more accurate test than the urine test. And there is the hair test also. The urine test is the cheapest one. So, most of the employers are using this test. The result also comes fast. It will take only an hour. The urine test is not very reliable. It can sometimes give a false result. 

The hair test will betray you if you have ever used any drug while the tested hair was growing. As said earlier the weed will remain in your blood stream seven to approximately fifty days according to the frequency of smoking marijuana. The hair growing during that period will have the traces of the weed even after the expiry of the period. Only if the hair is cut off the traces will disappear. That is the reason why some addicts shave their head. But if you are taking the drug test to obtain a job please remember that any suspicious act by the applicant may cause his disqualification. Very recent use of the drug may not show in a hair test. Apart from that it is a very reliable test. 

Then there is the sweet test. This test is taken by sticking a sweet patch on the body. The sweet patch will be kept there for about a week and then it is removed and sent to the laboratory for testing. A long term user can be detected by this test. Since it is time consuming it is rarely used.

Saliva test normally takes more than a week. Saliva has to be sent to the laboratory for the test. It is good to detect recent use of the drug. It is a very reliable test also. It is very convenient for the one who is tested.  

This marijuana does not do any good for your mind or body. It only harms the body and the mind. Marijuana ruins yours life. Instead of weeding out the deposits made by marijuana in your body is it not better not to use it at all? Excuses for the boys and girls using marijuana are not tenable. Some say that they use it because their seniors at home are using it. The excuse for others is that the seniors at school are using it. For some others it is for getting recognition from the friends and classmates. 

Lack of proper care and attention from parents is another reason for young people to fall into the practice of using the drugs. If the parents can monitor the activities of their children the parents can feel the changes in their offspring. The parents also can watch the friends the children have and enquire about their activities. 

The weed does not help in any way. It affects the memory. The use of marijuana hampers the motor coordination. If you use it for sometime you will get addicted to it. Then your relationship with others will get affected. If you use it longer you will have to use more and more to get a high. You will resort to criminal acts to obtain the necessary money.  

Only those who use the drug want to get the weed out of their system. The best way is to quit using the drug. Only time can properly cleanse your body of the weed. Some manufacturers are offering detoxification medicines for the purpose. These medicines are very expensive. Their effect is doubtful.
