I'm 9 days post extraction of my first molar on left. i am struggling to gauge when to get back to my normal routine as answers vary so much even from my own dentist. when is it safe to drink with a straw? chew on the surgical site? use my cbd vape?

At 9 days post surgical, chance of dry socket is minimal. Just to be prudent, stay off the straw for 2 full weeks. Same for chewing on surgical site, let it heal without traumatic insult. As to vaping, it desiccates tissues. In other words it harms all oral soft tissues, not just the ones that are healing. You are 9 days into a healthier life style. Don't throw it away.

Your own dentist should be able to tell you since they extracted the tooth and know if it was a routine or surgical extraction. That being said, if you had no post operative issues and the wound has closed, you should be able to resume pre-surgical routines.
