Welcome to HCM.
There is no easy way to pass drug test
. Drug tests are designed to override all kinds of masking techniques, otherwise those tests would loose authenticity.
Since you have indulged in unacceptable intake of things, you might as well face it and learn from this experience to be more responsible from now onwards and follow the regulations very strictly, if you wish to be successful in life. There is no easy way to success.
Wish you all the best.
