"Although the mean annual opioid analgesic overdose mortality rate was lower in states with medical cannabis laws compared with states without such laws, the findings of our secondary analyses deserve further consideration. State-specific characteristics, such as trends in attitudes or health behaviors, may explain variation in medical cannabis laws and opioid analgesic overdose mortality, and we found some evidence that differences in these characteristics contributed to our findings. When including state-specific linear time trends in regression models, which are used to adjust for hard-to-measure confounders that change over time, the association between laws and opioid analgesic overdose mortality weakened. In contrast, we did not find evidence that states that passed medical cannabis laws had different overdose mortality rates in years prior to law passage, providing a temporal link between laws and changes in opioid analgesic overdose mortality. In addition, we did not find evidence that laws were associated with differences in mortality rates for unrelated conditions (heart disease and septicemia), suggesting that differences in opioid analgesic overdose mortality cannot be explained by broader changes in health. In summary, although we found a lower mean annual rate of opioid analgesic mortality in states with medical cannabis laws, a direct causal link cannot be established."
Couldn’t the fact that we are standing on 50 gazillion square miles of molten lava possibly have something to do with global warming. Also, could I get one global warming “expert” to stand on the shore and tell me “this is where the elevation of the ocean is supposed to be.” Obviously if they are stating that ocean levels are rising, then they would be able to say if they are receading and base it on a line in the sand. Arguement also goes for glaciers. Exactly how many square miles of glaciers are we supposed to have. Seems it would take a rather large ego.
A note on the "hidden" material below : Each section of this guide includes – beside the common readings – three subsections, one for an analytical task , one for recommended readings , and one for related readings . To simplify navigating through the course guide, only the headings for these subsections are initially visible. The content of all these subsections are hidden (so that the beginning appearance of the page is similar to a standard syllabus) until the viewer clicks on the subsection heading, then its contents will appear. While this organization is helpful for negotiating the page most of the time, it can become an obstacle if we want to search the page (for example, for a particular article) as searches will ignore the hidden material. To overcome this limitation, it is possible to show all the hidden sections by clicking the § symbol at the top of the page (and simply reload the page to collapse all the "hidden" sections to their usual look). The table of contents at the top of the page will still work to aid speedy navigation to any section.
