Crack Cocaine - shelf life?

[BergenRichNYC]

Hey y'all is there a shelf life to crack or cocaine?
example lets say I found a rock in my house and I knew it was a year or so old? same for cocaine lets say I found a gram someplace knowing its a least year old.
This may come off as a silly newbie style question, but what ever.

I've never smoked crack but I imagine it'd be good for many years

Is it still good? Only one way to find out!

(But in all seriousness, yeah it’s likely still good)
