if you want to see a realistic movie about drug addiction watch trainspotting, i dont really care for requiem for a dream i mean towards the end its like "if you do drugs youll end up taking a double headed dildo in front of a crowd of cheering middle aged males in exchange for dope" or "if you do drugs theyll have to cut off your arm or consciously administer electroconvulsive therapy" you arent conscious during ECT they put you under
