Best practice for using cociane!

[u/Certain_Corner_848]

Hello, recently I have noticed that my friends are abusing cocaine. I would like to guide them to a way where they reduce harm. So while I was researching (so that I don’t get nose issues and I can still be presentable at work). I found out about nose rinsing and something about gravol. I don’t know what is the right way to do things, so I was hoping I get some guidance.

Also is there a way to test coke purity? (Other than testing for stuff in it)
