I mean, come on!!!! I've been guilty before of doing the 'cut & paste' of certain articles I feel are relevant, but at least I back them up with the sources they're quoting.
lol. i didnt claim to write the article. OK. So i shouldnt just cut and paste the relevent article but, I guess, demand this journalist's source notes for my internet arguments. Well, apparently this material is ammassed from at least 50 sources including The Scripps Research institue, Geroge Koob M.D,National Institute on Drug Abuse (NIDA) director Alan Leshner, Ph.D.Steven Hyman, M.D, and the NiDA brain imaging center. So if you think PBS is lying, contact these folk and see if they feel misrepresented. But You DO realize the science supports that addiction is real, an illness, a disease, whatever you want to call it, right?-Even if you don't agree with that? I'm sure this isnt the first youve heard about this information. I mean, this isnt some tiny, crazy, obscure opinin by a doctor in kallamoozoo, this is mainstream verity , supported by mainstream legitimate research for half a century.
There are 1000s or more studies on, and around this subject all supporting and charting this pathology. Anyway, good night

Although there are some cases where a person's reaction to first use is so positive that they immediately begin to abuse a drug, Koob says most addiction has a subtler start. It usually doesn't take place until the person has been using chronically. The person has become an addict when his or her brain has literally been changed by this chronic use of the drug, University School of Medicine
Many substances and activities, from food to sex, exert control over human behavior by motivating us to indulge in them. But addictive drugs, such as alcohol, nicotine, cocaine, and heroin, can affect the structure and function of the brain -- and hence our motivations -- in long-lasting ways. They can actually alter and "usurp," in one scientist's term, the "circuits" in the brain that are involved in the control of emotions and motivation, impairing an addicted person's will. "What addiction really is, is a result of brain changes that over time get translated into behavior changes," says National Institute on Drug Abuse (NIDA) director Alan Leshner, Ph.D.
If a person uses drugs, at a high enough dose, frequently enough and for a long period of time, these drugs change the way the brain works. "You change the way nerve cells communicate in such a way that you develop this compulsive, out-of-control use despite knowing that all kinds of terrible things can happen to you, and despite even experiencing many of those things," says National Institute of Mental Health director Steven Hyman, M.D.
Studies using new technologies show the precise effects of drugs on the brain. "In many cases, we can actually see changes in the structure of synapses and in the shapes of [brain] cells," says Hyman. A NIDA study released in 1996 provided the first direct evidence that chronic use of opiates (such as morphine and heroin) is linked with structural changes in the size and shape of specific neurons. Researchers at the Yale University School of Medicine found that rats chronically given morphine experienced marked structural changes in critical brain "circuits." Other NIDA studies have shown that altered brain circuits could be responsible for the major differences in brain functioning between an occasional cocaine user and a cocaine addict.
