::::Actually  the tobacco lawyer used the term  as did hundreds or thousands of non-tobacco people over a great many years.  This whole thing has become ludicrous indeed!    (American Patriotism, American Protest: Social Movements Since the Sixties  By Simon Hall; University of Pennsylvania Press, Jun 6, 2011,  224 pages, pp 109-110)  lists a bunch of totally independent usages - dating back to 1965 at least.   And not related in any way to tobacco.   I decline to believe in tachyons, so suggest 1965 was actually temporally before the 1970s. YMMV.
