I guess I'm not sure what the point of the comparison is. If the death rate from opioid addiction were 1000x lower, I would happily bite the bullet and say Purdue did nothing wrong. Chronic pain is real and terrible - it would be great to have a solution where the downside risk is no worse than an Adderall dependency.
In my experience, people who use amphetamines (and cocaine) regularly start making very bad decisions, and heavy use leads to amphetamine psychosis. A very public example of this was the behavior of the SBF / FTX / Alameda operation, where by several accounts regular amphetamine use was the norm. That doesn't mean it should be illegal, but I'd avoid associating with anyone I knew had an amphetamine or cocaine dependency.
