According to a study published by a team of Australian doctors in the latest edition of the scientific journal Respiratory Medicine, cannabis smoke does not pose a threat to the integrity and health of a person's lungs. Long-term follow-up and study of the lung health of a group of people who used cannabis only from a young age did not reveal any problems in terms of health and organ function, in contrast to people who mixed cannabis with tobacco or used tobacco exclusively during the observation period.
The study involved three groups of volunteers, aged 21, who were users of tobacco, cannabis, or both. Physicians have been monitoring them for the past 10 years, conducting regular examinations of the health of the lungs of the subjects, including analysis of their structure and tests of the functionality of organs. As a result, the doctors were able to establish that, unlike the groups of participants that included tobacco users, there were no dysfunctions in the field of lung function and health among the subjects who used cannabis exclusively.
“Among the members of the tobacco user group, severe signs of lung dysfunction and organ tissue damage were observed in all subjects. In particular, the problems were acute in those subjects who regularly used tobacco in large quantities almost every day. On average, less organ damage was seen in the group that used tobacco mixed with cannabis. However, among the participants in the cannabis group, physicians have not been able to detect any noticeable deterioration in terms of lung function or health, leading us to believe that, unlike tobacco smoke, cannabis fumes do not really pose a significant danger to humans,” the paper concludes.
“All subjects who used only tobacco, by the age of 30, that is, after about 10 years of regular smoking, there were visible signs of upper airway obstruction. Similar symptoms occurred in some members of the mixed group, but not among individuals who used cannabis exclusively.”
“In other words, based on observational data, it can be stated with a high degree of certainty that the active substances of hemp and their vapors released when they are heated do not pose a threat to human lung health at all, even in the case of regular and frequent use of the plant,” states the text of the work.
“In general, the results of the observations are in full agreement with the data of a number of previously published works, which also cast doubt on the arguments about the high toxicity of cannabis smoke to the lungs.”
Doctors also suggested that if cannabis smoking can pose any risk to lung health, it can be completely leveled by vaporizing plant material or extracts with cannabinoids, rather than burning them. This fact also correlates with the testimony of doctors and scientists who have studied this phenomenon, claiming that the control of the temperature of cannabinoid decarboxylation allows users to extract the active substances from the consumed product without foreign impurities, which can pose a much greater threat to health than the evaporation of cannabis active substances.
