Tolerance, or physical addiction is exactly that. A given dose is less effective after a certain amount of repeated use and a larger dose is required for the same effect. Not using the drug at all may cause withdrawal symptoms.

And now we’re selling a litre of iced coffee in a single serving vessel, which has 396mg of caffeine (or 475mg if you get the extra charged version).
