Alcohol, nicotine, marijuana, cocaine and amphetamines increase dopamine levels in the brain. Dopamine is a chemical transmitted between neurons that helps transmit feelings of satisfaction, arousal, reward or euphoria. As someone uses drugs, their brain learns to associate the drug with feelings of pleasure. The brain fails to reaffirm connections between pleasure and activities that the person used to find pleasurable. For this reason the old associations die, causing a person to feel less pleasure from the simple things in life like watching a sunrise or listening to their favorite music. The person continues to increase their consumption of drugs to fill in the gaps from daily pleasures, which they no longer feel. As the person's body becomes used to the drug, they develop a tolerance to it. A tolerance is the ability to consume a drug without feeling its effects. Although the drug may still be damaging the body, the person taking the drug does not feel as high or intoxicated as they used to when they first began taking the drug. They require larger doses of the drug in order to achieve a high. This pattern can continue until the person overdoses, dies, or increases their tolerance until they no longer feel any pleasure from the drug. When they aren't taking the drug they feel depression, weakness, or pain. These are symptoms of withdrawal. Withdrawal is the experience and associated pain occurring when a person stops taking a drug. In order to escape the pain of withdrawal the person may take larger doses of the drug just to function. Some users will increase their dosage to avoid pain until they overdose or kill themselves.

Cigarettes have been designed to be extremely addictive. People can develop an addiction to virtually any drug existing today. If you want to live a happy healthy life, you must recognize that drugs are addictive, and drug abuse is toxic to your body. The more drugs you take, the more prone to addiction you become. For these reasons it's important to avoid illegal drugs, all of which are highly dangerous and addictive, to only take prescribed medication as instructed by your doctor, and to only take over-the-counter medication when absolutely needed.
Use more than one strategy to give yourself a better chance of quitting. When you want to beat an addiction do not screw around! If you want to quit, you mean business. Hit that slime-ball addiction with all the artillery you have access to.
