Health - Cocaine usage frecuency and health damage

[flashcash]

so, SWIM has been doing blow for about 4 months now, SWIM used to do it 3 or 4 days a week but now has cut down to 2 or 3.
SWIM has never considered himself an addict and is an overall pretty healthy person. SWIM eats healthy, works out 3 times a week, doesnt drink at all and ocasionally smokes a ciggy or two (mostly when he's coked up).
How much harm is SWIM doing to himself by doing blow a few days a week (about 4 or 5 lines a day or 1/2 g).
Sometimes SWIM thinks too much about his coke usage and gets scared and thinks: "HOLLY SHIT, SWIM'S DOOMED!!!, SWIM MIGHT BECOME A FULL BLOWN ADDICT IN A FEW YEARS!!! ITS ALL I CAN THINK ABOUT!!!!!
but then the feeling goes away and swim gets back to his everyday life and enjoys being sober.
so, is it possible to use coke recreationally or will SWIM inevitably become an addict?? at the beggining it didnt even crossed swim's mind that he would be still doing it it 4 months later

it would be really relieving to hear from someone who's been using coke for a long time and is not addicted to it.
also SWIM would like to know if SWIY find it hard to go for a whole week or a weekend without the good ol' blow even if SWIY isnt an addict
