Telehealth with limitations like the person's home address and pharmacy must be within 100 miles of your clinic location would solve the problem for 99% of doctors. Maybe the distance could be debated. It would have to be within proximity to the doctors actual clinic, not like Talkiatry is leasing office space there but the doctor actually works 2000 miles away.
Anything that gives carte blanche for prescribing controlled substance completely over telehealth regardless of distance means the pill mills have total reach to anywhere in the country, which will just continue unsafe practice and bad medicine. Which is exactly what Ryan Haight Act was intended to prevent. It's just that the capitalism of mental health being scalable over telehealth creates a breeding ground for startups to function as drug dealers for stimulants, benzos, ketamine, etc, under the guise of improving access.
