Hello, I understand your concern. The time it takes weed to clear out of your system depends on many factors, like the frequency you smoke and the body fat. Marijuana is stored in the fat tissue and the leaner you are, the faster does weed clear out of the system. It stays longer in the system of people who are overweight. Generally, if you are a regular smoker it will take approximately 4-6 weeks to weed to get out of your system. If you are an occasional smoker, it will clear in 6 to 10 days. If you are going to get a urine test, drinking plenty of water the day before and on the day of the test will help flush it out of the system. This is the best and the safest method. Lastly, a word of advice. Please refrain from smoking weed while pregnant. There are several studies indicating that smoking weed during pregnancy affects the fetal brain development. Good luck with your job application and have a happy and healthy pregnancy.
