    Lognormal distribution
    refers to the theory, first propounded by Sully Ledermann in the 1950s, that alcohol consumption is distributed among the drinkers in a population according to a lognormal curve varying between populations on only one parameter, so that a large proportion of alcohol consumption is by a small proportion of drinkers. Although Ledermann’s particular formulation is now discredited, it is considered generally true that, in societies where alcohol is available freely on the market, drinkers are distributed along a spectrum of levels of alcohol consumption in a unimodal curve skewed to the left (referred to as the unimodal distribution of consumption, which also characterizes consumption of most consumables). The focus on the distribution of consumption in the population became associated with renewed attention to alcohol control measures to reduce levels of alcohol problems in a population; hence, this public-health oriented perspective is sometimes termed the distribution-of consumption theory.

    Lysergic acid diethylamide (LSD)
