Can you pass a drug test if you smoked 2 days ago?

Depends on the quality of the marijuana and the amount you have smoked.3

One a month ordeal or every day thing.

If you aren't a heavy smoker and only smoke once in a great while, then 22 days should be fine. Pick up a home drug test kit and check to see if you are in the clear.

It can take up to three months to pass a urine test, depending on your build, the amount you were consuming and the cut-off point required for the test. There are products available that will enable you to pass a urine test, provided you're not under the influence at the time of the test. The most popular product is Ultramask 1 hour liquid formula, sold as B-Clear in Australia.

Taken 1 hour prior to a urine test, Ultramask will allow the average drug user to pass their test, provided they are not under the influence of drugs at the time of the test and they are well hydrated, so diuretics such as alcohol and caffeine (including tea and energy drinks) should be avoided in the days leading up to the test.

It is recommended by the manufacturer that heavy users, or users with a bodyweight over 100kg, should also use Power Flush herbal capsules in conjunction with the liquid formula.

In Australia B-Clear and Power Flush are available over the counter through a variety of health food stores, hydroponic stores, bong shops etc.
