Getting drugs that were prescribed to someone else is not legal.

The prescription allows the person named on the script, and only that person, to possess and consume medication or drugs. And without a valid prescription, possession and consumption of those same drugs is illegal.

A prescription also means that only certain people can prescribe those drugs. And outside of that prescription system, distribution of prescription medication is illegal. Even intending to distribute prescription drugs is illegal.

How much trouble you can get into for sharing or giving away prescription drugs will depend on how much of a drug you are sharing or giving away, and who's prosecuting you. For instance, a conviction under federal controlled substances laws could land you in prison anywhere from 10 to 30 years. Meanwhile, you could be looking at a sentence from 1 year in jail up to five years in prison under California's drug laws.

Nvm I was trying to make use of these unused and sealed pills…whatever

You mean California has started prosecuting drug offenses? Good thing they are in NC.
Those drugs named are not a controlled substance but, should be disposed of properly.
Also, I doubt any prosecution of elderly medication sharing is going down in the CV of even the pickiest prosecutor.
Just sayn'
