1. Painkillers/Pain relievers = Painkillers are commonly over-the-counter medications which people take for headaches or fever. It can also be prescribed by doctors and it actually works with wonders if taken accordingly. However, if a person relies on it too often, this will lead to a higher tolerance for the drug. Thus, the person will need to increase his dosage every time in order to relieve himself from pain. A high dosage of pain reliever may lead to death.
2. Sedatives like "sleeping pills." = Sleeping pills are commonly given to people who have a hard time sleeping. Sometimes it makes people too dependent on them that they take it every day. This should only be used in a short-term period. This could lead to an abuse of using them and thereby increasing one's tolerance. This means that, the person will have to increase his dosage without the prescription of the doctor. In some cases, they seek medical help from other doctors to get an additional refill. If they ever decided to undergo rehabilitation, it will be hard for them to recover and they may experience the so-called "rebound insomnia."
