I'd say any psychological addiction is similar to a food addiction. Psychological addictions to different drugs don't vary very much because they are all essentially the brain yearning for an experience that normal living by itself cannot provide. The only difference would be strengths, and that again wouldn't help b/c food addictions vary in strength among people.
If I were to compare food addiction to anything, I suppose I would say cocaine. Stronger than weed but weaker than heroine as far as psychological addictions go, which is about where I suppose food addiction belongs.
If this is for a project of some kind, just go with crack. It seems that addiction to anything non-drug is compared to crack, so just go with something that everyone thinks they understand.
drug abuse could lead to drug addiction and dependence
Drug addiction would likely refer to an individual's struggle with a particular drug or drugs. A drug menace is when the problem sweeps a community or country (such as the current heroin epidemic).
There is actually no such thing as an uncontrollable addiction to a drug.
Tolerance to a drug (so that higher and higher amounts are needed in order to obtain the same initial effect) and dependence - both are part of the physical addiction. Psychological addiction does not involve physical tolerance and dependence, but can be difficult to treat, unless there is motivation to kick the habit.
