I hate to tell you this but you're just comparing one addiction to another and you're COMPLETELY INCORRECT about your addiction knowledge. I was a psych. therapist in a hospital and we handled a lot of addictions, guess which drug withdrawal we had to watch vigilantly due to it's severity? ALCOHOL WITHDRAWAL. In fact, we RARELY had to be as concerned about heroin withdrawal because those symptoms are not nearly as intense. I've seen people go into seizures from alcohol withdrawal. Case-in-point: you're very incorrect with your information.
To say that food, alcohol, and cigs are not nearly as addictive is completely ignorant. People become addicted to different things, it depends on their body chemistry, everyone does not react the same to each drug. In fact, AS SOMEONE WHO DID THERAPY WIHT MANY DRUG ADDICTS some could quit using heroin, but thought that kicking a cig. habit was the hardest thing in the world to do.
And as far as the statement "If it were truly an addiction, you would never be able to break it without medical intervention..." is NOT true. I have seen people break all sorts of clinically diagnosed addictions, without medical attention. Yes, medical intervention helps, but it is not 100% always necessary.
Instead of relying on your ONE EXPERIENCE with an addict to justify your argument, you should do some research.
An addiction is not classified as such by the extent of withdrawal, just because you can die from one and not the other does NOT MAKE IT ANY LESS DIFFICULT TO DEAL WITH!!!! An addiction is an addiction is an addiction, severity of withdrawal has NOTHING TO DO WITH IT.
Also, FYI food addiction is AN ADDICTION. The most addictive substances in our diets? caffeine, wheat, gluten, and sugar. Do not underestimate the power of food in your body. Breads and gluten substances increase serotonin levels in the body, they are CHEMICALLY ALTERING substances. Check it our for yourself. and even though "food addiction" is not in the DSM yet, it is being discussed and debated as we speak, if people did not think it met diagnostic criteria, then it wouldn't even be debated!
Honestly, please read up on your information before touting an uneducated opinion.
