The example cited above is a clear example of how labile and volatile the boundary between legal and illegal really is. The day before the political decision, marijuana was illegal. The day after, it had become legal and, a few months later, widely available in shops. At different latitudes and in different contexts, we all live in an environment in which rules are pre-defined, almost “parachuted” onto politically organized communities (most often, modern states) through legal and civil codes the design of which is neither consensual nor participatory. We are innately members of social groups with their own social rules, conventions, behaviours, attitudes and perceptions about what is morally acceptable and socially appropriate and what is not. We are educated and indoctrinated with the rules that are necessary to survive in our given society, fed with laws that we need to know in order to avoid bringing the coercive or punitive arm of the state down on ourselves. We learn the “dos” and “don’ts” of the environment(s) in which we are born, raised and eventually decide to live. Sometimes rules are relatively similar across environments, sometimes they differ radically and at other times they change significantly over time, either gradually or all of a sudden.
