Evidence that chronic cannabis users have an increased incidence of respiratory symptoms such as chronic cough, sputum production, dyspnoea, hoarse voice and chest tightness has been reviewed recently. 6, 10 As marijuana smoke contains many of the same compounds as, and shares similar properties with, cigarette smoke, respiratory symptoms would be expected. 11, 12

How beneficial is vaping cannabis to respiratory health compared to smoking?
While vaping cannabis reduces respiratory exposure to toxic particulates in cannabis smoke, the resultant reduction in clinically evident harms to lung health is probably smaller than that likely to result from substituting e-cigarettes for smoked tobacco due to the comparatively greater harms of tobacco than cannabis ...

How much does FVC decrease in marijuana smokers?
All studies reporting a significant decrease, ~1.5%, in FEV1/FVC ratio in marijuana smokers published incomplete data; in particular, most omitted the absolute results for FVC alone. However, two of these studies reported no significant effect on FEV1in chronic cannabis use.20,22Sherrill et al.34in a follow-up survey of a random, stratified, cluster sample of the Tucson population, aged 15–60 years (n=856 who had at least two measurements), found a reduction in FEV1/FVC of −1.9±0.7% and in FEV1of −142±44 ml only in previous marijuana smokers, with a nonsignificant decrease of −0.5±0.6% in current marijuana smokers.22Surprisingly, in 1,239 of the same subjects, tested on at least one occasion, FEV1/FVC was reduced by 0.5±0.6% and FEV1increased by 58 ml. However, in a population-based cohort born in 1972 and 1973 in Dunedin, New Zealand (n=1,037), Hancox et al.showed no significant association between chronic marijuana use and change in FEV1or FEV1/FVC at age 32 but found an increased FVC.32Subsequently, both Pletcher et al., in a longitudinal study over 20 years, recruited in 1985, examining Coronary Artery Risk Development In 5115 young Adults, and Kempker et al., in a cross-sectional study of 7,716 US adults from the National Health And Nutrition Examination Study cohort 2007–2008 and 2009–2010 surveys, reported similar findings as had Tilles et al.previously, although with a much smaller sample size (n=15 women).25,31,33Pletcher et al., reported that FEV1and FVC were 36 and 59 ml greater in cannabis users, with >10 joint-years’ smoking history, than in non-smoking controls.33Kempker27showed no effect on FEV1/FVC up to 20 joint-years but over 20 joint-years was associated with a 2.1-fold risk for FEV1/FVC ratio <70%, accounted for by a significant increase in FVC and no significant reduction in FEV1.25Interestingly, Tashkin et al.29reported a nonsignificant increase in both FEV1and FVC in a convenience sample of 144 heavy marijuana smokers compared with other smoking groups, and in another study, in the same subjects,39found that heavy habitual marijuana use, over a period of 8 years, was not associated with a decline in FEV1. Taken together, this information suggests that, although in some cases FEV1/FVC decreases by ~1.5% in chronic users, this may relate more to an increase in FVC rather than to a reduction in FEV1. This represents a major difference from the effects of tobacco smoking. The possibility that the effect on FEV1is due to selection of people with higher FEV1(because those with lower values do not smoke or do not continue to smoke cannabis) cannot be excluded in some of the studies.
Where does cannabis come from?
Cannabis comes from a flowering plant, native to central Asia and the Indian sub-continent. The genus includes three different species—Cannabis sativa, Cannabis indicaand Cannabis ruderalis. They produce two major active compounds, delta-9-tetrahydrocannabinol (d-9-THC) and cannabidiol (CBD); however, they contain 60 cannabinoids and over 400 compounds in total.2THC is the psychoactive compound, but it is modulated by CBD. The C. sativa-dominant strains have higher THC content, whereas the C. indica-dominant strains have higher CBD content.2The C. ruderalis-dominant strains contain even lower THC concentrations than the C. indica-dominant strains.3There is also ‘skunk-like’ cannabis, named for its smell, containing very high THC concentrations.4
Does smoking marijuana reduce TLCO?

Does cannabis have analgesic properties?
Experimentally, the acute bronchodilator effect5,6and analgesic properties7 –9of inhaled cannabis are well described. Acute bronchodilatation is due to THC.4However, as cannabinoids can have partial agonist, or even antagonist, effects, little is known about differences in airway effects from different strains of cannabis containing varying concentrations of cannabinols.
Does smoking cigarettes affect your lungs?
The effects of cigarette (tobacco) smoking on lung health are well known. They include symptoms of cough, sputum production (which when marked constitutes chronic bronchitis), wheeze and shortness of breath. Spirometric changes such as a progressive, largely irreversible decrease in forced expiratory volume in 1 s (FEV1) and FEV1divided by forced vital capacity (FVC)−FEV1/FVC ratio occur. This ratio is the most reliable measure of airflow obstruction. These changes may be accompanied by air-trapping within the lungs, measured physiologically (as increased total lung capacity (TLC) or residual volume (RV) or the ratio RV/TLC) or radiologically, on chest X-ray, etc. Chronic persistent, progressive airway narrowing, damage to the alveoli (emphysema) and effects on small airways (investigated with more sophisticated methods, beyond the scope of this review), in varying proportions, comprise the condition chronic obstructive pulmonary disease (COPD). As cannabis was thought to affect the lungs in similar ways to tobacco, it was logical to use spirometric measurements to detect the adverse health effects of marijuana. However, with concurrent tobacco smoking, it is difficult to separate changes due to cannabis from those due to tobacco.
