Addiction

Addiction is an intensive craving that comes over your body and it needs what it searching for.  This can be for candy, foods, drinks, alcohol, nicotine, and so on.  The users get an addition to the feeling fro his or her drug choice.  For example when someone is addicted to heroin, the don't crave it to stick  needle in their arm or because they like doing that, they crave the euphoric and relaxing feelings that come with it.  An example of how bad addiction can get is Bassist from Motley Crue, Nikki Sixx.  Nikki overdosed one day at a party from heroin and died the ambulance picked him up and Emt's gave him two injections Narcan where he was revived.  Mr. Sixx was released from the hospital and upon returning home he shot up again.  So to rewind, Nikki died from heroin, hours later he shot up again after already dying.  You cannot  control addictions, you can only control trying something for the first time.
