Hi,

I had my last unprotected exposures 2 years ago. I tested negatvie one year later, 3 days ago via Oraquick negative and today received 4th gen negative result. I am a chronic marijuana smoker (3,4 times a week) and I am wondering if my weed smoking habits can cause false negative results? I have smoked marijuana the day before my last HIV test (10 hours before test). I was told by my doctor that he thinks it does not impact HIV test results.

Best,

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about the the effects of smoking marijuana on HIV test results. As marijuana does not have short or long term effects on the immune system, [1] it should not cause false negative test results.

If the 4th generation test was taken outside of the window period, the results are considered to be conclusive.

Regards,
