&gt; But I don&#x27;t understand how people can be so pro marijuana on one hand, and so anti-opiates on the other.<p>It&#x27;s probably the hundreds of thousands of dead people from opiate overdoses vs the 0 dead people from marijuana overdose.<p>&gt; I would guess a majority of adults in the US have had Vicodin or similar and I don&#x27;t know anyone personally who ever got addicted.<p>You almost certainly know someone who has been addicted, you just didn&#x27;t know. It is shockingly common.
