Biomechanics of Vaporizers
This particular device provides a simple yet efficient mechanism through which the active elements of plant material or beneficial blends are released. The vaporizer is engineered in such a manner that it does not burn the ingredients and as a result produces a vapor with a unique scent. The plant material is heated at a very low temperature in contrast with traditional methods and the produced vapor has negligible, if any, particulate matter while the presence of harmful gases and other by-products is substantially diminished. During this process combustion and the resulting toxic fumes are totally prevented while simultaneously obtaining the same outcome.
Three types of Vaporizers
The first type is called the direct heating vaporizer (also known as conduction vaporizer), the name is derived from the very fact that the method used involves the plant material such as tobacco or marijuana coming directly in contact with a heating element. The latter serves the function of igniting the material into particulate matter or vapor state which is then inhaled by the consumer as it remains hanging within the glass-enclosed space Another kind of vaporizer is called the indirect heating one which follows a similar mechanism with the difference that this time the material is jammed inside a tubular glass vial-like chamber and then heated at a reduced temperature as aforementioned with the vapor emerging for inhalation from the other end of the tube. Besides, it is important to note that such a vaporizer considerably diminishes the concentration of carbon monoxide and gases released. One more variation of vaporizer models utilizes a heat gun to infuse the plant material with the necessary amount of heat through a side opening of the flask-shaped glass. When the heat and material are effectively combined, vapor is released from the upper part of the flask with the optimum temperature for marijuana to produce the best vaporization being at around 240 degrees Celsius/464 Fahrenheit.
Mechanism of Vaporization
Technically the vaporizer involves the transportation of gases and solid particles through an air conduit also referred to as pneumatic conveyance. The introduction of liquid matter such as water or ice allows fluidization to happen which in turn traps the vaporized particulates. Afterwards these fluidized particulates are pushed forward to the user after defeating atmospheric frictional forces and gravitational forces through the application of pneumatic transportation. Appropriate dimensions play a vital role when it comes to dealing with the avoidance of any mechanical blocking of the vaporizer and relevant communicating channels. This aim is achieved by making the latter around three to five times the size of greatest particle size. It is also logical that the density of the plant material being vaporized affects the transport velocity and decreases the pressure inside the communication channels in direct proportion the velocity of inhalation.
Mechanism of Particulates and the Human Respiratory Tract
The structure of human breathing can be categorized into approximately two main areas which are the Upper Respiratory Tract and the Lower One. The Lower Respiratory Tract consists entirely of the lobes of the lungs while the bronchial tubes, trachea, larynx, pharynx, nose, mouth and sinuses are attributed to the Upper one. The interlining of the breathing tube (trachea) is constituted from goblet cells that force out neutrophils, lymphocytes, antibodies and other severe catalysts to immerse the throat. The lower part of the trachea, at the point where the two main-stem bronchial tubes disconnect towards the lungs has a sensory area called carina which brings about the cough reflex if an abundant amount of phlegm or dangerous dust or heat find their way in. In addition, since the bronchial tubes are a continuation of the trachea they possess identical arrangement and act likewise in reaction to substances which are not recognized as forming part of the body. This process is described as the immune response. Floating particles sometimes surpass the size of 0.0005 millimeters (0.5 microns) and hence they are sensed by the bronchial tubes and trapped in the interlining as a result. The other particles which are smaller than the stated size of 0.5 microns remain undiscovered and make their way into the lungs. Plant material such as tobacco and marijuana produce particles which belong to the latter group and thus make it to the lung tissue. Nowadays since people are becoming more and more aware of the medical conditions connected with smoking together with steeply rising prices to cope with considerable taxation, the smoking habit is declining drastically. However, in parallel the amount of people smoking marijuana has been on the increase at a steady pace. Also, recent years brought along new methods of consuming marijuana rather than just smoking it such as edibles, dabbing and vaping. Vaping and edibles are very popular among the younger generation which seems to be the most aware that smoking is damaging to our well-being and indulges in these non-smoking alternatives with enjoyment.
Biomechanics of cannabis sativa (marijuana)
The biomechanics of marijuana differ a great deal from those of tobacco. The active elements of cannabis sativa contain cannabidiol and delta-9-tetrahydrocannabinol among other obtained products which are together termed as ‘cannabinoids’ (see figure below). Several studies were carried out by the United States Institute of Medicine which were instrumental in discovering exclusive human biomechanics in connection with this essence when arriving at the bloodstream. These included pain reduction, muscle movement control reduction and memory reduction together with a function in the immune system. However, since the immune system has several distinct aspects the methods are not so apparent since cannabinoids utilize receptors which are disparate from the usual anatomy.
Approximately, around 10-20% of people suffering from conditions like chronic pain, HIV/AIDS, multiple sclerosis and epilepsy smoke cannabis for healing intentions. From one particular study it was derived that when marijuana was smoked a reduction of pain by a factor of 34% was shown. This figure is treated as substantial and meaningful by statistics. Further more than half of the marijuana group stated an over 30% decline in pain in comparison to less than 25% of the group that was not utilizing the plant material.
