Addiction is an intense craving, seeking out, and use of a particular drug. There are a lot of reasons why people use drugs but to me the most harmless way is when you get surgery and the doctors prescribe you with pills which cause your body to crave for more which causes you to become addicted which turns into popping perks or crushing them up or snorting them. Some people are peer pressured into doing drugs while others think doing drugs will take their stress away. This video was a great detailed example on addiction to me. If you have a friend or a love one and they are on drugs please get them help as soon as possible because our young people are killing themselves, everyone is doing everything looking like zombies or ten times their age. What's worst is the amount of money people spend just to get high then wonder why they're broke. More importantly is the stress and pain they put on their love through. People who are on drugs attitudes and behaviors change and they start lacking on their hygiene, their role as a parent and their professionalism at work. Take care of your body its more to life than being on drugs.
