>"There is no convincing evidence that prior prescription opioid use caused subsequent heroin use. ... This is much like the argument, popular among drug warriors, that marijuana is a gateway drug because most users of hard drugs start with marijuana." Except there are actually studies and data that do show a link between prior prescription opioid use amongst heroin users, along with a demographic shift: https://jamanetwork.com/journals/jamapsychiatry/fullarticle/1874575 https://jamanetwork.com/journals/jamapsychiatry/fullarticle/... And the second part of that comment "This is much like the argument, popular among drug warriors, that marijuana is a gateway drug ..." is a total strawman.
