Of course it's not suggested however some people suffer from long term chronic pain and need a strong enough medication in order to at least have some quality of life without laying paralyzed on a couch. Unfortunately cannabis is not strong enough to accomplish the type of pain relief necessary for people in this condition and there are millions and millions of these people. That said one of the major negatives of long term intake of opiates is also long term , or at least while in taking said opiates, which also means long term use of laxatives which creates a whole new internal problem for those millions as well. However it is absolutely possible to limit useage of those opioid s simply by adding medical marijuana into the equation in an effort to reduce the pharmaceuticals.
When suffering with chronic pain there's a spread 1-10 of the severity of the pain. Generally speaking people are not at level 8 or 9 thruout the day. They might start the day in a little pain, level 2-3, but within a couple hours watch it advance to level 5, 6 in which case a lower amount of narcotics will probably suffice for at least a few hours. If at some point medical pot is added it seems to help lengthen some of the effects of the drugs without lengthing the destructive capabilities or adding more pharmaceuticals. It's all an individual thing, how much pain are you in but it's definitely possible for people who suffer at level 7 and 8 to lessen the intake of the opioids by adding pot to the mix and in a significant enough way to then also experience less of the negatives with an ultimate goal of using more pot and less pain pills. And that would be a good thing.
It is criminal for what these legislators do in writing laws that not only force people into taking risks simply to live a life of minimal pain and I repeat minimal pain as the pain is NOT going way no matter what you do, the only thing a free society can do is "allow" that sick person to make every attempt at living as normal a life as possible and pot absolutely does that for millions of us around the globe . I have nothing nice to say about people like mitt romney who would like to see people hurt even more.
