Yeah, definitely don't try to get them off the street if you don't know what you're doing then. I haven't gotten any shrooms in 10 or so years, but when I did my girlfriend and I had a guy for weed and we just asked him. I don't know the scene around Maryland, but I know around here you can't get anything off the street without risking fentanyl or xylazine (knew a guy who dipped joints in formaldehyde too for some reason) which none of that you want to mess with if you care about a single thing. I'm not thinking shrooms would be as risky as trying to get any kind of pills, but depending on who you go to, it could be (personally, I wouldn't it risk it from people I don't know well).

I probably wouldn't even do a study unless it was "bring some friends to the park and have this toast," which I don't envision studies being like that.
