Why, Do People Become Addicted?

[MUSEical]

Put simply, people become addicted because they are uncomfortable sober. Whether it be anxiety, pain, depression, the causes are simple and similar. There may also be a genetic and environmental aspect to it, but all of those explanations can get quite complicated. GS

+1 on this. I've known people who can take anything, even highly addictive substances and never even care to take it again. While on the other hand I've known people to experiment with something and it go downhill really, really quick. There's most definitely a genetic and environmental component to it. It all depends on the person. Everyone is different.
