Another song is often known as "Cocaine Blues" but is completely different; it is also known, in its different versions, as " Take a Whiff on Me" and "Cocaine Habit Blues". This song has three families of variants.

To our knowledge, no forensic studies have been published on the applicability of low‐cost NIR spectrometers operating in the relatively limited spectral region of 740–1070 nm.

After the first verse, there is no similarity in the lyrics.

Some users report feelings of restlessness, irritability, and anxiety. The psychoactive and pleasurable effects are short-lived without continued administration. Continued use, or even a first-time use, can be dangerous and deadly. Do employers test for cocaine?

Cocaine is metabolized primarily in the liver, with less than 1% of the parent drug being excreted in the urine. Avery S. New ingredient in cocaine vaccine shows promise in mouse study. Duke University. Feb. 6, 2020. https://medicalxpress.com/news/2020-02-ingredient-cocaine-vaccine-mouse.html Conventionally, simple colorimetric tests are used to obtain a first indication of whether a substance contains a frequently occurring illicit compound. According to the NIDA, this drug-drug interaction is the most common two-drug combination that results in drug-related deaths. Death can be due to due cardiovascular (heart) death, stroke, or other organ toxicity. A well‐known limitation of these cobalt(II)thiocyanate‐based tests is their false‐positive (FP) response to several common adulterants such as levamisole and lidocaine.

As NIR spectra, in general, and these small‐range spectra, in particular, are relatively information poor, a subsequent derivative preprocessing step is often suggested to put emphasis on the spectral differences. Consistent with an earlier NIR study on narcotics from Liu et al,

Eventually, a tolerance to the high develops. Many addicts report that they seek but fail to achieve as much pleasure as they did from their first exposure. Some users will increase their dose to intensify and prolong the euphoric effects. While tolerance to the high can occur, users can also become more sensitive to the anesthetic and convulsant effects without increasing the dose taken. This increased sensitivity may explain some deaths occurring after apparently low doses. Even though the recreative use of this drug has been banned for years, cocaine abuse is still increasing. In 2020, the annual report of the Drugs Information and Monitoring System in the Netherlands revealed that around 6.5% of the Dutch population has used cocaine at least once. The sympathomimetic properties of cocaine are related to the above-mentioned inhibition of noradrenaline reuptake via noradrenaline transporter (NAT). Because cocaine impedes this reuptake of noradrenaline, and thus increases its availability, there will be an increase in the stimulation of the α- and β-adrenergic receptors, and an augmented adrenergic response—which relates to the marked vasoconstrictive properties of the drug (responsible for a few of the cardiotoxic effects) [ 2, 82, 83]. demonstrated the correct classification of the origin and quality of rice by both kNN and SVM machine learning models applied on short‐range (740–1070 nm) NIR spectra after multiplicative scatter correction as preprocessing and PCA for data dimensionality reduction. Another example is the detection of counterfeit tablets among genuine pharmaceutical products for several active pharmaceutical ingredients. It is interesting to compare youth numbers of cocaine use with marijuana use, the most commonly abused substance. Past-year use of marijuana / hashish in 2021:In the forensic field, colorimetric tests are accepted to provide a presumptive result suitable to detain a suspect and to select samples for confirmatory laboratory analysis. Only the laboratory results are subsequently used as evidence in court by the prosecution.
