Times are changing; not fully changed yet, but in some kinda transition as the cooler young ppl of the 60's/70's become older and assume more of the roles of power in society. As this happens, the newer ideals/values will continue to become more of the accepted norms. Also, lets face it, altho some older generations still embrace the lunacy, the entire "Reefer Madness" movement has been fairly well debunked as having been based mainly in gov't orchestrated, media-exaggerated hysteria.
