The conclusion was that - at least, for mice - those were the most addictive among all the drugs tested." Having been the rat pushing the lever, I have to say that I think the researchers came to the wrong conclusion. They are mistaking the compulsion to obsessively take the drug with the difficulty of withdrawing from the addiction. One of the effects of the drug, like a feeling of euphoria or being kept awake, is a strong desire to do more while the drug is active in your system. Once doing more is no longer an option (for whatever reason) the crash, or 'withdrawal' is very short. The whole experience seems to have more in common with a manic depressive episode than anything else. In some ways I'd have to say that cocaine is not addictive, certainly not in the same sense as opiates. Doesn't mean it won't kill you, doesn't mean people don't ruin their lives over it. I remember seeing film of that experiment in some class I took in college, roughly 1968-69, oddly enough. Nicotine is addictive in the same sense as opiates, but mildly so. That is my experience of these things at any rate. I debated not posting this, but there is so much bad information being accepted as gospel that I decided I had an obligation. It's no wonder that when people who actually do drugs hear the official opinion they just role their eyes. I know it's just anecdotal, but I'm inclined to believe my experience, plus my observations of all the people I've run into in similar circumstances. ARS PS I'm tempted to take on the 'but pot is 100 times stronger than it used to be' canard, or the 'crack is more addictive than coke' proposition, but will not. Suffice it to say that while there is some truth in both statements, they both leave enough out to effectively be lies if presented as any kind of defining summary.
