The liver doesn't actually "absorb" anything. Instead, the liver filters toxins such as alcohol and drugs, taking the toxins out of the blood. The liver can filter about one drink per hour. The liver breaks down toxins to other by-products and tries to render the toxin as "less harmful" to the body. The by-products are then returned to the bloodstream to be excreted via the kidneys and bladder.
As a side note, "drug tests" are not necessarily testing for a certain drug as it is sold at a pharmacy. Instead, the drug test looks for certain by-products created when the liver filters the toxins within the medication. For example, users of cocaine who also drink alcohol often have a specific chemical that is only created from cocaine plus alcohol. A blood test or post-mortem toxicology would be looking for that secondary chemical, especially if it has been hours since the person "used" or if it was hours after the person's death.
