Something like 25% of people who “try it once” will go on to be problem users. So don’t.
I had to call an ambulance for one friend cos he stopped breathing in front of me.
I woke up on my kitchen floor 45 minutes after a shot. I had time to cap the needle before I passed out and had no idea I was about to go down.
Another mate died because she used at home alone while her partner was at work.
Other than that, it’s a pretty nice high :)
