Hi everyone, I'm 16 and I smoke marijuana every other day or so. I recently went to the doctor for blood work and was told not to eat like for 8 hours beforE, so I didn't, but I had smoked like the day before, after I got the test results back. My ldl cholesterol level was so high that it didn't even show up on the charts!!! Could someone help me with my situation and tell me how long before blood work to not smoke??? Help please.
