There might be some risk with idiots taking z packs for colds and creating more super bugs but there's definitely less stupid ways of doing this.

People who take critical stuff regularly usually have to ration drugs so they have a store in case of emergencies. If you travel somewhere and you forget your life saving drugs you then have to spend a good chunk of your trip grovelling to the pharmacist and doctor (depending on the drug) to get an emergency refill if the drug is even available in that location. The whole system is bonkers.
