I remembered the # of joints, but just confirmed the amount and its 9oz/month...leave it to the federal government right?

As far as respiratory issues, I have never seen any medical record (nor would I discuss them if I did), but my Client is a public figure/activist for medical marijuana and addresses this question regularly. You can find videos online of him discussing this and many other issues if you are interested, but in short he claims no negative respiratory effects and 34 years on this dosage.
