Sometime during summer I will be going to a new doctor, so he needs to do a routine lab where I'll be given a blood test and maybe a urine test.

I was wondering how long I had to go without smoking to be able to pass a blood test, and if there was something I could do to help pass the test.


Thanks in advance.
