Thanks for your vote of confidence, but all credit and truthful reasearch goes to Dr. Tashkins of U.C.L.A., and Dr. Melanie Dryier, Dean at the School of Nursing in Iowa. These people have done hands on independent research with no politcal/corporate people to please. I, like you, have only used cannabis in my life and my lungs are just fine. My MD's at Stanford University tell me that i am as healthy as any 20 year old they have seen, with a very healthy set of lungs. I will be 50 in Oct. Fuck. lol.
I will always tell people to do what they think is right for them when it comes to making personal decisions. If i felt that cannabis was making my life unmanagable, whether it be my health, my mental health or posed any threat to my grandchildren, i would be the first to revisit that which i find so much pleasure in doing. The truth, education, and keeping myself approachable is how i choose to deal with the issue with my kids and grand kids. It works for us. Teaching fear and spreading mis-information will eventually destroy any family/society. My 14 year old grand-daughter knows more about cannabis and it's uses than most adults. I am proud of that. To this day she remains cannabis free/drug free/ no sex/no booze/no tobacco. Which will always be her choice, one way or the other. I see no point and no justice in lying to her about drugs or any other topic. Education is the answer to any problem or postive adventure.

peace and happy new year to you and yours,
