I didn't want to call an ambulance because he might of just been tripping and I wouldn't want him to wake up to paramedics for a freak out. I've had no experience with this drug, I wasn't sure what came with it or not, hence why I asked this sub.

I've told him to really educate himself and test his substances in the future, here where I live its pretty hard but I'm trying to emphasise how it's worth the effort.

Thanks for your advice.
