well nobody replied to my previous thread, and my friend's now in hospital. i was not there at the time. he had been having a headache for about 6 hours after ingesting an oral dose of amphetamine sulphate (a normally unharmful dose despite the difference in people), then he started to throw up repeatedly and get dizzy. he lay with these effects for a couple more hours before he started getting short of breath and his heart started hammering.
at this point my friend called an ambulance.
this is my question, why did he react so badly to it when me and my friend had stuff from the same batch? he has taken amphetamines before and has had no ill effects. i was not there but from the description of the symptoms i would have personally waited to see if they had developed before ringing the ambulance, as i believe he was just having a bit of a bad time, rather than a medical emergency. opinions?
