Lead, u referring to the medical delivery of free marijuana or free delivery of fairly priced mmj? I like the price but made a comment on hiz pozt of "I don't want it completely legalized!" Or something like that. Cause he/she may have to pay more for a liquor type license to make bundles more of $. Cept, if those prices are real, I'll take some! i am an equal opportunity opportunist! meddeliv!
Limiting myself, so short form. Ran out of room so you'll just have to imagine the rest! So read Granny Storm Crow info, while you can!

Smoking and cancer, ask Weedhound! She made it very clear what her doc told her in her thread, check it out.

I believe the study you are referring to is the recent one that came out last week, which said Austrailia did a study and said one tobacco cig. eqivalent in size, etc. to one joint of cannabis is the equvilent of 3 tobacco cigs in the effect to your lungs. Same paper, size, etc.
Last Fall they said it was no longer true.
As they came up with these same figures and findings approx 27 years ago, 3:1 ratio! So, it will be overturned in the future. Seems totally irrelevant.
What will happen to your lungs IUD--first look for worms in your nose. then an IQ of 0, then snails out of your ears and blue lips, blue digits-fingers toes or loss of them completely, coughing so hard you hit the wrong keys. Basically, over the years you'd become an irritating asshole due to the lack of oxygen to whatever is between the snails and worms!
