Sorry to butt in, but with non-traditional treatments, and most natural drugs and preparations, general practice physicians are not properly equipped, trained, nor encouraged to step outside the box when prescribing. There is not enough certified and/or approved information available to risk their practice or license on. Take MMJ (Medical MJ) for instance - few MD's will officially condone or approve use for these same reasons, even though they may accept the efficacy non-professionally.
With Schedule I and II drugs readily available on the street, regulation would be a good start to getting these drugs out of the shadows and the court rooms, so research and information can be gathered objectively; then MD's and Psychologists could make informed and beneficial recommendations. Also, drug companies would have the green light to certifying and marketing many of these substances. Groundwork has already been laid, but most research has been silenced and buried by governments since the 1960's through protest and legislation. Research suggests that some substances such as LSD are both safe and effective:
From Wikipedia: LSD was brought to the attention of the United States in 1949 by Sandoz Laboratories because they believed LSD might have clinical applications.
In one study in the late 1950s, Dr. H. Osmond gave LSD to alcoholics in Alcoholics Anonymous who had failed to quit drinking. After one year, around 50% of the study group had not had a drink — a success rate that has never been duplicated by any other means.
From the late 1940s through the mid-1970s, extensive research and testing was conducted on LSD. During a 15-year period beginning in 1950, research on LSD and other hallucinogens generated over 1,000 scientific papers, several dozen books, and six international conferences. Overall, LSD was prescribed as treatment to over 40,000 patients successfully (no one died or suffered physical contraindications).
