Welcome to SR uncertain21
Binge using of harmful substances in part of addiction. Not all that are addicted to coke or any drug have the same using pattern as most people that are addicted. Typically an addict will use daily, but for some people they use on the weekend only.
Binge users can have the same legal, health, family, work and a host of other serious problems as the person that is using daily.
There is no safe level use of coke.
Its time to stop if your using and SR can help with that.
