It’s the “like candy” part. People are on antidepressants, anti-ADHD, hormonal birth control constantly for
years and much longer than these meds were tested in clinical studies. Some severe side effects are downplayed or ignored if they only develop after this long-term use. Women in particular are often not taken seriously by practitioners, check out current lawsuits surrounding hormonal IUDs (mentioned side effects include heavy migraines that happen to end up in dangerous intracranial hypertension in many). Gynecologists don’t even check for a family history of thrombosis when handing out the pill.
Alternative solutions that don’t involve selling pills for years are underexplored to the point that research is actively prohibited (e.g. psychedelics against addictions or depression).
