It depends on the drug type and dosage - and what is called "synergistic effects". That means that there are molecules in milk / coffee (like lactose in milk - a sugar - and caffeine in coffee - a stimulant) - that could potentially bind with the drug molecules - if they are chemically binding. You may increase the potency of the drug dosage or neutralize it entirely or even have other nasty side effects. If you're talking about prescription drugs, you'll get a guide print out with the pills to alert you of any potential synergistic effects - in other words - what not to take with the drug. Nearly all drugs are tested and calibrated in neutral pH water - which is usually what you use to swallow the pills. Street drugs don't carry such warnings and consuming them with other liquid substances, like alcohol and benzodiazepines can result in respiratory arrest - and death. The same is true with opiates. We've lost many talented people in their prime this way - never chance it - each of us has different tolerances to drugs - and street drugs are not tested in science labs - they're usually graded for potency by street addicts - not a reliable source of information.
Well it depends on what kind of pills were talking about. If were talking about narcotics, ( pain killers such as percocet, morphine, fentanyl, oxycodone, etc. etc.) Then some people say that calcium or vitamin D counter acts the opiods, meaning if you take them for pain as directed or are even abusing them, then the milk or calcium or vitamin D would stop you from feeling them at their strongest. But, I don't know if this is true. Its only what I've heard, and I've heard it from quite a few people.

The consumption of milk after taking certain medications can inhibit the proper metabolizing of the scripts to the extent that one may end up totally negating or magnifying the effect of such drugs anywhere from 7 to 10 times their normal potency. This reaction may indeed cause an "overdose" of sort necessitating medical intervention. Caffeine? Safe Journey
