How does one host their own beeper server?

Edit: found it

This is very good advice, especially if someone has taken drugs. Please tell us. The medicine I give for chest pain can kill someone if they’re having that pain from doing a ton of cocaine and not a possible heart attack.

After the first time someone went into cardiac arrest after I started treating them after telling me they didn’t use any drugs or alcohol today - I followed up found out he survived but had in fact taken a ton of cocaine today, I’ve changed my wording to “Have you taken any drugs or alcohol recently? It’s okay if you have I’m not a cop but if you have it changes which medicine I can safely give you.”
