Never done anything IV, but I do plenty of drugs (cocaine included) during basically every weekend, and have been doing so for the last ~30 years more or less.

Sure, some people do fall down into the trap of doing something too much, this is true for lots of things, including video games (which I've been more addicted to than drugs at some points in my life). But if you have a kind of normal life during the week that you like too much to lose, then it's not that hard to keep your drug usage to where it's accepted, for your sake and others.

I do love cocaine, but seeing what happen to others when consuming things too much, is a great tool to avoid liking it too much so it takes over your life.

Its like eating. Most of us do it every day with no issue, and some of us are mindlessly munching and experiencing negative effects of obesity.

Aren't 45% of US adults obese?

The same way you cope with anything, really: You consciously develop a personality that handles whatever you face in life. Some people call this process "growing up". I think it's more spiritual than that.
