Read the law here...

To make an educated choice on the matter, don't listen to the pro-29er, or the anti-29ers, read the law. The one section that looks to me to mean that money can go out of state, is the research fund.
"Sixty percent shall be deposited into the HOPE 2010 Research Fund for the purpose of grants and loans to support research into the prevention, early detection, treatments, complementary treatments and potential cures of lung cancer and other types of cancer, cardiovascular disease, emphysema and other tobacco-related diseases, including, but not limited to, coronary heart disease, cerebrovascular disease, and chronic obstructive lung disease, which shall be awarded on the basis of scientific merit as determined by an open, competitive peer review process that assures objectivity, consistency, and high quality. All qualified investigators, regardless of institutional affiliation, shall have equal access and opportunity to compete for the funds in this act. The peer review process for the selection of grants awarded under this program shall be modeled on the process used by the National Institutes of Health in its grantmaking process..the rest of the money seems to be earmarked for your state.
If the money coming out of smokers pockets, and people selling cigs means more research is done on fighting cancer...real research and that money can go to the best institutions, in Cali or out..I myself would have no problem voting for it, if this was a PA law up for vote.
I can see your argument that the money should stay in Cali, but if there are better places for research throughout the county, why not help them out.
