I went to a southeast asian country and got a staph infection. I walked down to the pharmacy, asked the pharmastst for a topical and an oral antibiotic. 3 days later i was healed, continued the course the rest of the week and that was it. $12 dollars american.
I got another staph infection previously in the united states. Needed to go to a doc in the box who misdiagnosed it. A few days went by and i needed to go to another doc in the box who gave me topical and trued to give me a steroid shot. Needless to say it progressed and turned into fullblown MRSA which required admitance and a IV antibiotic. Extremely painful. I don't have the ability to add the costs but north of $10k easily.
That's why drugs should be legalized.
Okay question was about drugs that are contraindicated for all medical purposes like heroin.
Also do you see any ironic connection between your two examples: easily accessible antibiotics and a medically resistant infection?
>"What is the argument for legalizing drugs that are contraindicated for all medical purposes, are toxic, and have a high addictive potential?
I'm sorry that happened to you. Sincerely. That sounds incredibly frustrating, painful, and scary.
I think your maximalist conclusion of "drugs should be legalized" might have some second-order effects that might be net worse for society, though. Addiction, misuse, MRSA, overdoses, etc.
