Sort of: Regular heavy drinking and problematic alcohol use can be diagnosed with certain liver enzyme tests and other blood tests and biomarkers of alcohol intake such as GGT, CDT, PEth. Drug problems can't be diagnosed by liver tests per se but blood, urine, and hair can be tested for drugs of abuse or their metabolites. Interpreting these tests is not always straightforward depending on the context.
