On what basis? Does him taking your "life saving medication" somehow make it less effective for you? Or are you concerned that if normal people take for performance enhancing reasons that'll cause the government to crack down and impact you negatively? If that's the case, shouldn't your ire be directed at the government for instituting said crackdown, rather than adults making decisions for themselves?
Imagine if asthma medicine became so trendy that you had to hike up a mountain to get it. Great. If I could do that, I wouldn’t need the medicine in the first place.
I liken it more to a shortage of insulin and everything the diabetic can eat screws with their blood sugar horribly because that's how society kind of works for someone with ADHD and executive functioning. Everything is frustrating, everything is waiting, everyone seems so fucking slow (and it's not their fault you have to give people grace), everything basically "drains the tank".
I have to work with my doctor and the pharmacy in order to adjust my prescription so I could be prescribed the right kind of medication that works for me that also jives nicely with what the pharmacy inventory gets and I also have to make sure none of this looks like drug-seeking behavior so I have to talk with full disclosure with my doctor and be very forthright with frustrations. It's been a nightmare since the shortage happened. And if I didn't have other people in my life that care, I wouldn't be able to handle any of it on my own especially during the months when getting my prescription was more than just the next day after my prescription runs out usually.
So, uh, one time I mentioned to my doc that sometimes my meds were wearing thin by lunchtime. He wrote for another 15 pills that month so that I could break some in half for an additional half dose at noon. (I’m on a low dose of my stuff. Adding another half wasn’t a Dopesick jump or anything.)
Turns out, because ADHD I often forgot to take the afternoon dose and ended up with a couple weeks of buffer. That was a nice outcome on its own.
Both are true. Neither will happen. So... yay society.
