Okay, I'm going to put up my two cents.
1) Yes, it is kids who crush and snort their medications until the bottle is done that makes doctors wary of prescribing it to people who have a legitimate use for it.
2) You have ADHD and are medicated for it with a given monthly aliquot; except you abuse and run out of your medication so now you use vaporized methamphetamine. The latter essentially nullifies the therapeutic benefits of the former.
You have to admit that you are truly addicted to stimulants and should take a look in the psychological mirror.
I've wanted to ask this for a while but due to social taboo here of the question I have refrained until now. Problems that you may have are likely intwined with your lifestyle. What do you do in your average week? Are you in high school? college? do you have a job? Are you preparing for doing any of those?
Where do you see yourself in 5 years? I hope it's not living in your mom's basement vaping meth, ranting with anti-grammar and posting memes on the internet.
I don't mean to rub it in; I just don't want to sit idly by with thoughts I have about your life situation, and by not expressing them, condoning your current path.
