unless you overdose, opiate use doesn't affect lifespan or mental acuity.
the first list of nasty stuff listed are temporary side effects, the second is withdrawl and getting dopesick. the thing is, despite the dramatics of the symptoms you can tie a heroin addict to a lampost, come back three days later and find them alive, the same isn't always true when it comes to serious drinkers or housewives who eat benzos like cookiemonster. BP-up, heart go pop. me garfield. roar.
