it has nothing to do with inspecting meds, its about spreading false information from a single anecdote
One cop may have felt like he didn't care enough to ask for your LP bottle as proof and accepted your note, but he or any other cop is in no way obligated to accept that, so you're just testing your luck. BY REGULATION, the only proof is your bottle. the mere fact that you are saying things like "dont be a dick" means you are accepting you are at the discretion of the officer. if you are a legal patient with an LP bottle, you can be a dick as much as u want, they cant do anything
whether you are caught with or without your bottle, nobody is going to look at your meds. you can refill LP bottles with weed bought elsewhere and have that legal, but i dont recommend walking around with a doctors note and weed in a baggie, thats not accepted by law
