Description: A new concept for a CDS has been developed under a Phase I ARPA funded program; it uses gamma resonance absorption (GRA) to detect certain illegal drugs that may be transported in man-portable containers. A high detection probability for heroin and cocaine is possible with a device that is also searching for explosives. Elemental detection of both N and Cl is utilized, and with tomography, a 3D density image of the elements is generated. Total density image is also developed. These two together may be used with considerable confidence in determining if heroin or cocaine is present in the interrogated containers in a small quantity (1 kg). The CDS employs a high current ({ge}10 mA) DC accelerator that produces a beam of 1.75 or 1.89 MeV protons. These protons impact a target with coatings of {sup 13}C and {sup 34}S. Depending on the coating, the resultant resonant gamma rays are preferentially absorbed in either {sup 14}N or {sup 35}Cl. The resonant gammas come off the target in a conical fan at 80.7{degree} for N and 82{degree} for Cl; a common array of segmented BGO detectors is used over an arc of 53{degree} to provide input to an imaging subsystem.

Heroin: Legalization for Medical Use

Heroin: Legalization for Medical Use

Date: March 14, 1984
Creator: Blanchard, Randall, IV
Description: This report discusses the limited legalization of diacetylmorphine (heroin) for use in the medical treatment of intractable pain. The report attempts to present pros and cons on the issue as well as information on pending legislation. The report also provides a comparison of heroin's analgesic qualities to those of currently available and equivalent pharmaceutical alternatives.
