Doctors are all knowing gods and I know nothing after 2 years of pharmacy technology college, 5 years of experience with over 40 drugs and 14,500 pills, so just ask them <end sarcasm>
Ignore this advice, their are some good doctors out there and if you are not satisfied always seek a professional opinion.
This guy has been banned now, he is not a professional, has not authority to prescribe any medication, no right to push people into asking for meds he deems that will work for them, no right to recommend cannabis and certainly no moral right to tell a 13 year old via PM what drugs would work best for her (yes she reported the PM).
As a result, the mod team has removed him from the site.
