Man, I'm not trying to preach to you or anything but our brains aren't fully developed until around 23-27. That is based of what I have studied so far in college majoring neuroscience (Ultimately getting a degree for Pharmacy tech, or Physician Assistant). Anyways, I have HBP, SVT (A form of tachycardia that often causes heart attacks/or even heart failure), & Permanent nerve damage. All from taking 20mg of vyvanse one time and i was prescribed it for treatment of my ADD in 2012 [I was 16 then, 19 now]. Worst week of my life. Sure, the pediatrician who was writing that and didn't do more testing to make sure a pro-drug of Adderall that goes through your red blood cells instead of your liver or kidneys first is in prison. But I have to live with all of that. And Take up to 3 Xanax a day (never abused them, been taking since 2012 when the vyvanse incident happened.) for PTSD, And panic disorder. Unfixx said stay away from opiates/benzos until you're older. Which I can definitely see why with the opiates. I have Scoliosis w/ spondylolisthesis, spinal stenosis, L-5 disk Slipped down, etc you get it. I was written Vicodin (hydrocodone 10 mg & APAP 325 mg) kuzz of being jumped at school all the time. And the APAP (Tylenol AKA Acetaminophen) Caused me to have a certain type of liver disease. And now I'm off anything that causes a high risk of liver damage. I'm fine now on a high dose of 60 mg Morphine E.R. (MS Contin) 3 times a day around the clock from my pain management doctor. I do take it for pain and to get high, I'm being honest. & For ADD i take ritalin 20mg, it's awesome for me, but everyone's different. I apologize for this being so long. But my rambling was from seeing ''the effects of drugs on teenage brains is highly overstated". Bruh lol I hope you understand some stuff now. Peace for now, and i know I'll get downvoted like hell, but idc. If anyone can learn from my experiences idc if you downvote me
