Only people that don't have any experience/knowledge of what drugs are like say that.
A bit of blow every 4-6 weeks is not a big deal. The last party got cancelled, then went ahead with only ten people. People there were passing out coke and pills but I declined, because there's simply nothing to be gained from it.
In a larger social setting good coke just gives you a bit of confidence, makes you a bit more chatty, which is helpful if you're an introvert and often stuck in your head.
Coke is inconsistent, even in the UK which is presumably a major market when compared to some Eastern European Country. I can say with 100% certainty I could never touch it again.
Likewise, when I was going out regularly, I preferred MDMA/ecstasy. And a) I only saved it for special occasions, 2-3x a year to avoid building a tolerance b) everything was tested with reagents to make sure it was legit and c) everything was measured out into decent dosages.
The only time I've had a "drug" problem was with mephedrone aka bath salts, because that shit was legal so you could order it online, and because it was legal and cheap even if you didn't buy any, everyone on a night out would be passing it around like candy.
