Hello,

Thanks for using health care magic for posting your query.

I have gone through your question in detail and I can understand what you are going through.

However I would require a couple of more details to help you in answering your query in a better justified way.

1) If this question is for you, I would like to know how much you take and since when? Are you a heavy user of marijuana?
2. Do you have any other medical issues?

Hope to hear from you at your earliest convenience.

Regards and wish you good health,

I took marajuana on XXXXXXX 6th and 7th. I had my drug test on XXXXXXX 26th. I had two or three hits each time. I only weigh 120 lbs. I have a fast metabolism and I work out every day. I drink a lot of water every day to help.

Brief Answer:
7-12 days

Detailed Answer:
Hello
Considering the fact that you do not use marijuana regularly and it was an isolated exposure on 6th and 7th XXXXXXX its unlikely that the test will come positive on 26th. Mostly in cases like yours, marijuana will get washed off in 7-12 days which is much before 26th. So mostly it should not bother you.
Hope this helps,
if you have any further query, do let me know.
Kind regards
Dr. Srikanth Reddy MD
