Most drug users I know take them infrequently, myself included. Everything in moderation. For example I've used cocaine a handful of times since 2011. The last time was October last year. At the moment I'm in a straight arrow stage because exams are looming and I've got too much to do -- I've not so much as had a pint of beer in over 3 weeks. Just because someone takes drugs it doesn't make them a junkie. Addiction is a choice IMO.
