Rise in Marijuana Use among American Seniors

A strange and rather surprising trend was reported in today's news. The headline screamed out "Marijuana Use by Seniors Goes up as Boomers Age". These were the same folk who enjoyed the magic drug back in the 1960s and 1970s. Now they are back at it after retirement, to have some senior fun and relaxation.
I wonder if this is the example today's youth should be emulating? What will be the future of today's youth if the trend continues? During the 1960s and 1970s the communications and transportation was not so rapid. Drug trafficking was not so rampant, even if that generation was hooked on "grass" it was not this easy to get it, I suppose. Now with the proliferation of markets and easy availability of the drug and with so many senior people to emulate, I wonder what lessons the youth will learn when they read this article.
Too many questions and too few answers...
