BACKGROUND: Despite public awareness that tobacco secondhand smoke (SHS) is harmful, many people still assume that marijuana SHS is benign. Debates about whether smoke-free laws should include marijuana are becoming increasingly widespread as marijuana is legalized and the cannabis industry grows. Lack of evidence for marijuana SHS causing acute cardiovascular harm is frequently mistaken for evidence that it is harmless, despite chemical and physical similarity between marijuana and tobacco smoke. We investigated whether brief exposure to marijuana SHS causes acute vascular endothelial dysfunction.
METHODS AND RESULTS: We measured endothelial function as femoral artery flow-mediated dilation (FMD) in rats before and after exposure to marijuana SHS at levels similar to real-world tobacco SHS conditions. One minute of exposure to marijuana SHS impaired FMD to a comparable extent as impairment from equal concentrations of tobacco SHS, but recovery was considerably slower for marijuana. Exposure to marijuana SHS directly caused cannabinoid-independent vasodilation that subsided within 25 minutes, whereas FMD remained impaired for at least 90 minutes. Impairment occurred even when marijuana lacked cannabinoids and rolling paper was omitted. Endothelium-independent vasodilation by nitroglycerin administration was not impaired. FMD was not impaired by exposure to chamber air.
CONCLUSIONS: One minute of exposure to marijuana SHS substantially impairs endothelial function in rats for at least 90 minutes, considerably longer than comparable impairment by tobacco SHS. Impairment of FMD does not require cannabinoids, nicotine, or rolling paper smoke. Our findings in rats suggest that SHS can exert similar adverse cardiovascular effects regardless of whether it is from tobacco or marijuana.

Abstract – Mayo Clinic
The opioid crisis that exists today developed over the past 30 years. The reasons for this are many. Good intentions to improve pain and suffering led to increased prescribing of opioids, which contributed to misuse of opioids and even death. Following the publication of a short letter to the editor in a major medical journal declaring that those with chronic pain who received opioids rarely became addicted, prescriber attitude toward opioid use changed. Opioids were no longer reserved for treatment of acute pain or terminal pain conditions but now were used to treat any pain condition. Governing agencies began to evaluate doctors and hospitals on their control of patients' pain. Ultimately, reimbursement became tied to patients' perception of pain control. As a result, increasing amounts of opioids were prescribed, which led to dependence. When this occurred, patients sought more in the form of opioid prescriptions from providers or from illegal sources. Illegal, unregulated sources of opioids are now a factor in the increasing death rate from opioid overdoses. Stopping the opioid crisis will require the engagement of all, including health care providers, hospitals, the pharmaceutical industry, and federal and state government agencies.
“A complementary and necessary approach is to target the “demand” side of opioid use, namely, implementation of preventive measures, educating physicians, requiring physician continuing education for opioid prescribing licensure, and addressing why patients use opioids in the first place. Indeed, prevention of initiation of use is the only 100% safeguard against addiction; however, millions of patients remain addicted, and they need comprehensive, rather than perfunctory, treatment. Rummans and colleagues are absolutely correct in their delineation of the unwitting consequences of a focus on pain, given that a perceived undertreatment of pain fuelled the opioid epidemic in the first place. They are correct to point out how effective pain evaluation and treatment are much more than prescribing and should routinely include psychotherapy, interventional procedures, and nonopioid therapies. In addition, we have described the crossroads between pain and addiction as well as successful strategies to manage patients with both chronic pain syndromes and addiction.”
CONCLUSIONS AND RELEVANCE: In this study, our findings indicate that while individuals who
use cannabis or cigarettes during adolescence have an increased risk of subsequent psychotic
experiences, epidemiological evidence is substantively more robust for cannabis use than it is
for tobacco use.
