From my past experience in real life and also listening to the stories of others here at SR....my thoughts are that using cocaine is ALWAYS a problem, whether used daily or occasionally (which usually leads to daily in very short time), I have never once heard anyone say "Cocaine made my life better."
It's a harmful, illegal drug that has destroyed lives and killed our loved ones.
Nope, from where I sit it is never okay.
I wish you luck and send hugs because I know this must be a very emotional difficult time for you.
Hugs
