Kay stole and abused all ADHD drugs when a teen. That includes Ritalin. We found it in her room! Somebody in the know told us that Kay and her little crowd of dysfunctional drug users both crushed it for snorting and sold it for money. Yes, I am ashamed that she sold drugs.
Adderrall is more preferred because it is stronger than Ritalin, I hear, but all of these drugs are speed. They would not be so carefully monitored if they were not so greatly abused.
Also I have many relatives on SSRI antidepressants. While they were told that these drugs were not addictive, getting off of them was as hard as any addictive drug. Look up SSRI withdrawal. I am afraid of SSRIs after seeing relatives in agony while trying to wean off these medications.
