yes we already have needle safety, what to do incase of a overdose, opiate withdrawal survival (makes me feel like a proud parent ) and others, don't mean to sound untoward but aren't you the one who wanted to try codeine as a one time thing? bit odd that you are collecting needle data and such. if your just being helpful my apologies
PS: i agree with china_white.. hanging out in an opiate forum aint the best place for someone who wanted to do opiates as a "one time thing"
