Addiction can occur more easily to some individuals than others. Not only is it the addictive power of the substance, may it be drugs, alcohol, or even caffeine, but it is also depends on the individual and the individual's environment. Humans have always had a curiosity in experimenting with things that alter them both mentally and physically. It is just human nature. This is how many addictions occur, mainly drug and alcohol addiction.
There is an array of different drugs, prescription and non-prescription. Addiction can occur in a number of ways. If and individual is using prescription drugs, such as Ritalin, and they are taking doses higher than recommended they can become dependant on the drug. If they abruptly stop taking the drug or dramatically lower the doses they may become depressed and feel extremely fatigued. To counter these symptoms they continue using the harmful drug to make them feel what they think is normal but is actually increasing their dependence on the drug.
Non-prescription drugs are usually experimented with in adolescence, probably because this is when many people are most insecure and experience the most peer pressure. From my experiences I have noticed that teens feel the need to fit in and if it is "cool" to experiment with drugs than many insecure teens will do it. Most teens can quit after experimenting with drugs for a while but some can't. Of course it depends on the harshness of the drug, but even with the lesser addictive drugs such as marijuana a person can get addicted. Then people can sometimes become too disoriented to deal with reality.
Heroine is probably the most addictive drug and the drug that has claimed most lives. Heroine is a form of morphine. Morphine, named after Morpheus, the Greek god of dreams. It is widely publicized by the media and the most famous drug probably because of all the famous people that have been killed by it possibly making the drug more attractive. Media both reflect and influence
