When the procedure was over the woman said she was feeling better already, demonstrated how much better she could walk and departed.

Other patients were treated with much the same procedures, the doctor never once referring to notes or formulas as he mixed up sometimes six and eight injections for a patient. Dr. Jacobson delivered his potions in the skin covering the hips, neck, jaws, abdomen and knees.

Statement by Drug Bureau

In recent years Dr. Jacobson has been investigated several times by the Federal Bureau of Narcotics and Dangerous Drugs. In response to an inquiry by The Times, a bureau official gave this statement:

“Dr. Jacobson was the subject of a compliance order conducted on March 6, 1968, that developed numerous recordkeeping violations.

“In October, 1969, following another investigation, seizure was ordered of all controlled, drugs in possession of Dr. Jacobson. This action is currently, being contested in a civil action’ brought by the subject and pending before the civil section of the Federal District Court for the Southern District of New York.”

Although the bureau's investigation has been going on over almost five years, no action has been taken to charge, Dr. Jacobson with any violations or to prevent him from carrying on his practice.

State Investigation

The Division of Professional Conduct of the New York State Department of Education, which regulates the practice of medicine, said that it too had an investigation of the doctor in progress.

Dr. Jacobson said recently that his practice is now “busier than ever.”

Dr. Lawrence Hatterer, a New York psychiatrist who has treated several victims of amphetamine overuse, including several former patients of Dr. Jacobson who became psychotic, believes that some persons are particularly susceptible, to dependence on such stim‐’ ulants.
