Persian heroin in the San Francisco Bay area: 1977-1980.

A new type of heroin has increased in frequency in the San Francisco Bay Area in the past three years. "Persian" heroin, coming to this country from Southwest Asia, differs from commonly-seen heroin in several ways: (1) distinctive marketing channels, (2) different routes of administration, (3) increased purity, (4) more severe withdrawal, and (5) different demographic characteristics of users. "Persian" heroin users tend to be younger and more likely to be White and unemployed as compared to other heroin users.

Addicts' attitudes toward drugs: a semantic-differential study.

The Drug Rating Scale, an adaptation of the Osgood semantic-differential technique, was devised to measure the connotative aspects of attitudes toward drugs. Sixty-two heroin-addict clients and fourteen staff members of the Haight-Ashbury Free Medical Clinic completed the Scale. The Addict group tended to regard heroin in a negative light, possibly consistent with their own lack of self-esteem. Amphetamines and LSD had the greatest distance from heroin in the addicts' "semantic space"; this was consistent with addicts' relative preference for alternative drugs to heroin. The evaluative and activity dimensions provided a plausible assignment of the eight drugs inquired about into four quadrants.

The heroin epidemic in San Francisco: estimates of incidence and prevalence.

Much attention has recently been focused on the question of the extent of heroin use in America. In a worthwhile effort to call public attention to the problem, many estimates of its size have evidenced a tendency toward exaggeration and aggrandizement. This paper presents methods of estimation of the extent of heroin addiction which, when carefully employed, should effectively correct such distorted estimates. Two general types of estimation are employed, incidence and prevalence. Incidence estimates are concerned with new cases of heroin addiction that occur in a specific population within a given amount of time. These estimates are based upon self-report data from addicts regarding date of first addiction. When corrected for the "lag phase" (that period of time between onset of first addiction and eventual visit to a treatment program), these data permit accurate retrospective charting of incidence trends. Prevalence estimates focus on all known cases of heroin addiction in a specific population within a given amount of time. Three separate types of prevalence estimates from three separate sources are outlined in this article: estimates based on overdose death data, estimates based on crime statistics, and estimates of "unknown" addicts. In outlining these methods, this article describes the fluctuations in heroin addiction in one major American city, San Francisco, California. After analyzing data gathered from a sample of 2,367 addicts contacted over a 3-year period, this study suggests that the incidence of heroin addiction seems to have declined after 1970. Possible factors underlying this apparent decline in heroin addiction are then discussed, including the post-1970 maturation of the "population at risk," the effectiveness of antidrug media messages, the changing drug fashions in the heroin subculture, and the gradual deterioration of the quality and potency of street heroin.

The use of propoxyphene napsylate in the treatment of heroin and methadone addiction.

The use of methadone in the treatment of heroin addiction continues to be controversial. Propoxyphene napsylate (Darvon N(R)) is a possible alternative and a pilot study was conducted to test its acceptability, safety and clinical efficacy in treating long term, "multi-relapse" heroin addicts. Findings indicate that propoxyphene napsylate suppresses many of the symptoms associated with opioid withdrawal phenomena. It should be viewed as a very promising therapeutic tool to be used in conjunction with psychological counseling and socio-vocational rehabilitation in detoxification and maintenance therapy for heroin or methadone addiction.
