Be honest and ask yourself: What is a "responsible drinker?  In all fairness to pot smokers, the main reason to smoke or ingest these things is an "effect" on the human body.  "Responsible" drinkers would hardly support the vast alcohol industry and all the "effects" of alcohol, both good and bad, have been well-documented. The "bad effects" contribute to the imbalance of insurance, health care and long-term detriments to society everywhere in the world. Those who have studied the "effects" of pot ingestion worldwide, see some similarities but not the degree of devastation of alcohol abuse.  The "responsible drinker" comes up against one serious problem; the tolerance effect of alcohol.  In order to achieve the same "effect" long-term, I think it is well-documented that larger doses are needed.  So logically, a "responsible drinker" is one who never builds tolerances, e.g. not drinking for the "effect." Both pot and alcohol users drink for "effect" - a fact, for better or worse.
