STD: Stds do show up on blood tests--if they are tested for. Syphilis, hiv, hep, can be revealed in blood, as some herpes. The others like chlamydia and gc are done with swabs. But "routine" blood tests don't "screen" for these diseases.

It can: Usual blood tests do not test for weed. There are specific tests for week, but usually urine is tested rather than blood.
