Drugs are addictive because they either mimic or stimulate the production of brain chemicals that cause feelings of pleasure. After a period of time, your brain adjusts to the higher levels of the chemicals, and it becomes necessary to use more drugs to get the same effect.
Eventually, you reach a point where -- due to the changes in the brain -- you need to use the drug to maintain something like normal functioning. At that point, having become dependent on the drugs to function, you experience severe withdrawal symptoms without drugs. These symptoms usually are the opposite of whatever effect the drugs had, and in some cases -- especially tranquilizers and alcohol -- they can be life-threatening.
