I’d recommend reading a bit on Erowid[0] or checking out Michael Pollan’s book How To Change Your Mind.
In general it’s important to trip with people you trust, in a safe place you are ideally somewhat familiar with, and with as open eyes about your current mental landscape (what’ve you been excited about? What’re you struggling with in your life?). Set positive intentions for your trip!
If you do find yourself wanting someone to talk to either during or after a trip, please reach out to the Fireside Project peer support line[1] (I’m a volunteer here, this is a cause and domain very dear to me)
If you do decide to trip, know that you are loved, experience is positively weird (both on and off drugs, eh?), and… welcome!
