Question: Hi,

So I have a hair test for my internship tomorrow. The last time I smoked was a little over four months ago. I had smoked less than ten times in the months prior to quitting. Will I pass my test tomorrow?

Brief Answer:
most likely

Detailed Answer:
Hello,
Thanks for using healthcaremagic.

I read your query and understand your concerns.

Cannabis can be detected by hair test upto three months after the last use. Since you smoked it four months back there is very good chance (read 100%) that it will not be detected positive for scheduled hair test. The chance becomes very slim as you were infrequent user.

I hope this helps you.
If you have more questions feel free to write back to me.
If not please close the query and rate the answer for my future patients.
Thanks and regards.
