The reactionary politics come coupled with idiotic films and ‘comedians’ who glorify excess, e.g. The Hangover (and many, many others), portraying drugs and alcohol as ‘cool’ and ultimately harmless.
Case in point: last night there was a lot of ecstasy, cocaine and LSD flowing around in a rave here in Buenos Aires. So far half a dozen people are dead, they had body temperatures of up to 42 ºC. Why? Because ‘it's cool and you can't tell me what to do’.
It doesn't help here that the organisation which ruled this country for the last quarter-century derived their profits and their muscle from the drug trade, so controls have been, to say it politely, relaxed.
