The lead author, Dr. Lorenzo Stafford, an olfactory expert in the department of psychology at the University of Portsmouth, summarizes his findings: " the higher the caffeine consumption, the faster the consumer recognizes the smell of coffee. These caffeine consumers are thus able to detect the odor of a highly diluted chemical in coffee at much lower concentrations, and this capacity increases with their dependence. So, the more they want caffeine, the more their sense of smell seems to develop for coffee ".
The smell, a recognized stimulus but also a marker of dependence
The team looked through 2 experiments to see if there were any differences in people's ability to feel and respond to coffee odors, depending on the importance and regularity of their consumption. The results clearly indicate a link, with heavy coffee drinkers being more sensitive to the smell of coffee.
- In the first experiment, 62 men and women were divided into non-consumers, moderate consumers (1 to 3.5 cups of coffee per day) and large consumers (> 4 cups of coffee per day). Each participant was blindfolded and, to test his sensitivity to the smell of coffee, had to recognize very light aromas of coffee vs other odors. They had to identify the aroma of coffee as quickly as possible. The most diligent consumers are able to identify coffee at lower concentrations and with greater speed. Each participant having previously informed his coffee consumption by questionnaire, the analysis confirms a link between these data, the precision and speed of recognition of the aroma and his desire for coffee. This increased need or dependence is thus also linked to a greater sensitivity of the odor detection test.
- In a second experiment, 32 other participants, divided into consumers and non-consumers, passed the same test for detecting coffee odors. This second group confirms the results of the first.
Researchers already know that olfactory signals (eg, the smell of alcohol) can cause cravings among substance users. This study shows, for the first time, that this olfactory sensitivity is a mark of the degree of addiction: its results indeed suggest that changes in the ability to detect the olfactory signals of a substance constitute a useful index of dependence.
The results therefore suggest that olfactory sensitivity is dose-dependent dependent on the degree of addiction to the substance. It is therefore a rather simple marker of the state of dependence but also a stimulus that can be used to put an end to certain addictive behaviors such as tobacco addiction or cannabis addiction.
For previous research has shown the effectiveness of aversion therapies, which consist of training patients to associate an odor with something unpleasant to induce them to develop an aversion to the odor in question and therefore to the associated substance.
Here is what you want to know before seeing your local medical dispensary:You will require a physician’s recommendation, medical cannabis certification, and/or whatever proper documentation is required by your state. Typically, you must be 18 or older to qualify for a medical consent, but exceptions may be made in some conditions for minors with particularly debilitating problems. You will often enroll with a medicinal dispensary. This is to keep your medical cannabis recommendation or certification on file for regulatory and legal purposes. There will be a waiting space. This will be to control the circulation of product and patients, but a simple dividing wall gives patients privacy and direct one-on-one contact with a budtender to discuss medical issues. Many times, but not always, your purchases will be tracked by medical dispensaries. This process can help budtenders and patients monitor effective medication in addition to have a living record of producers and products for future reference and follow up. Medicinal dispensaries usually permit you to smell and analyze the buds prior to purchase. This might vary from state-to-state.
