Patient Question

Hello Doctor,

 

If I have a yearly check-up tomorrow and they will do blood work, and I smoke weed the day before, will anything be elevated?

 

Answered by Dr. Elver Martinez

Hello,

Thank you for reaching out to Dr. Galen. Please find the below response to your query.

 

Generally, marijuana can remain in your system for about one to seven days, depending on factors like your metabolism, how frequently you use it, and your overall health. While it may not directly cause significant changes in most routine blood work, certain tests, like liver function tests or markers related to drug use, could potentially show some elevation. It's always a good idea to inform your healthcare provider about any substances you've used prior to your check-up, so they can interpret your results accurately.

 

Thanks
