I tried to find some definitive info,but most of it was high tech serious medical mumble jumbo,something a doctor or medical researcher would certainly know how to read,which I am not even close to being,but I did find a few links relating other peoples own experiences with smoking herb and dealing with asthma,a person would have to make their own decisions of course whether it was good or not,http://www.cannabisnews.com/news/thread7749.shtml is one of the sites that has some interesting info,and some 'testimonies' from people who have asthma and smoke.
The biggest obstacle the herb has is because there is so much dis information or no information or very little information,and what we think we know could only be limited to our narrow scope of given information,what we see,what we hear,what we've been told,etc.So when someone tells me what they 'know' about herb I like to listen,do my own research,and try to add that information to my knowledge,is it true,is it not?,and granting that there is
so much more going on so quickly in so many fields of study,surely I won't be
able to know it all,nor do I ever want to profess that I do,can any of us know,all of it?We can only listen and learn,and if we are lucky we can pass it on,and teach.But always in the nicest way possible,because that is the best way to learn.
Peace out
