The name “proteuus indi” has come to be associated with various types of illegal drugs.
In recent years, the term has also been used to refer to crack cocaine, which has been linked to a range of health problems including addiction, obesity, cardiovascular disease, diabetes, cancer, and a host of other conditions.
The new research, published in the Journal of Neuroscience, shows that crack cocaine activates the same neural circuits that are associated with addictive substances.
As a result, it appears that crack may be a new and potentially addictive drug with potentially severe side effects.
“There is no doubt that crack has a long and storied history of use as a recreational drug, but it also has significant addictive properties,” said Dr. Daniel J. Wachter, a professor of psychiatry at Harvard Medical School.
“There is also an increasing recognition that crack is addictive and should be considered as such.”
The researchers used a technique known as electrophysiology that uses electromagnetic fields to detect electrical activity in the brain.
Dr. Wacheter explained that the researchers were interested in crack because it had been shown to activate the same brain regions associated with drug addiction.
According to Dr. Wachet, the researchers also used a technology known as functional magnetic resonance imaging (fMRI) to show that the drug was also able to activate areas of the brain involved in reward.
This allowed the researchers to show the drug has the potential to be addictive.
“The research team found that the same regions of the cortex that were associated with cocaine addiction were also involved in the reward-related brain activation of crack cocaine,” Dr. J. Robert King, the study’s lead author, told Newsweek.
While there have been previous studies using positron emission tomography (PET) to look at crack cocaine’s effects, Dr. King explained that this is not a reliable method of detecting the drug’s addictive potential.
Instead, the scientists used a different method known as magnetic resonance spectroscopy (MR-SEM).
This is a more precise technique that involves a combination of MRI and other imaging techniques, and involves a person performing a series of tests on the subject.
It is also a method that is less sensitive to detecting the addictive properties of crack.
Dr. King said the new study adds further evidence to the fact that crack should be a safe, legal drug that should be used as part of any health-care regimen.
“We now know that crack does not cause addictive effects, but we also know that it has potential addictive properties that should not be underestimated,” he said.
Other studies have found that marijuana users show reduced dopamine levels in their brains, which could be associated a decreased propensity to use drugs.
