“Marihuana smoke, UNLIKE CIGARETTE SMOKE,
causes broncho-dilatation rather than broncho-constriction and,
UNLIKE OPIOIDS, doesn’t cause central respiratory depression”
Researchers from the Boston University School of Medicine.
New England Journal of Medicine, 1973.
Airway resistance decreased by 38 per cent in the higher-dose group.
The airway was expanded or unblocked by 44 per cent.
Significant positive change in the lungs’ airways in the low-dose group.
Cannabis containing 2.6 per cent THC was inhaled by nine study participants.
One per cent THC was inhaled by the other eight.
Heart rate increased 28 per cent in the higher-dose group, while this side effect was not documented in the lower-dose group.
Previous cannabis-smoking was known among all study participants.
FDA authorization was provided, with a Grant of Confidentiality from the U.S. Department of Justice.
The highest professional status in medicine was achieved by the lead researchers over the next 50 years, with credentials such as: Dean of Medicine, Chair of Psychiatry department, research fellow.

Psychiatrist, research fellow, professor, and chair of his department, Dr. Louis Vachon, who last year died just shy of this 85th birthday, worked at Boston University School of Medicine for 52 years as psychiatrist, research fellow, professor, and chair of his department.
Inhaling cannabis can make for easier breathing because it dilates – or opens up – the airways in the lungs, said the 1973 study published in the New England Journal of Medicine.
