The contemporary uses of hallucinogenic plants and mushrooms: a qualitative exploratory study carried out in France.

Characteristics and behaviors of ketamine users in France in 2003.

The increase in recreational use of ketamine in France led to the carrying out of a survey aimed at depicting the sociological profiles of French ketamine users, their addictive behaviors, and the characteristics relevant to the use of the substance. This survey is based upon the analysis of 250 questionnaires, 24 semi-directive interviews, and two focus groups. Data was collected between July 2002 and June 2003 among individuals who had used ketamine at least once since January 1, 2001.

[High-dose buprenorphine substitution during incarceration.].

MANAGEMENT OF OPIATE ADDICTS: OBJECTIVE: To describe the social and medical profiles of incarcerated (in detention or after sentencing) opiate addicts, whether or not they had already begun substitution treatment at arrival, and assess the impact of high-dose buprenorphine substitution therapy on the health of prisoners and the course of their incarceration. METHODS: A prospective survey was conducted on opiate addicts on admission to prison and after 2 months of incarceration, from December 2001 to February 2003, in 6 prison centres in the South East of France. RESULTS: During incarceration, no significant difference (other than in medical follow-up) appeared between the prisoners receiving substitution treatment and those who went through withdrawal on arrival.

[Risk factors of early drop-out during induction of high-dose buprenorphine substitution therapy. A study of 1085 opiate addicts].

Background: The revelation of an acceptable rate of users still treated one year after initiation of a substitution program with high-dose buprenorphine (HDB) has contributed in the validation of the interest of the molecule in this indication. However the frequency of early drop-outs (after the first consultation), when treatment is set-up, is frequently evoked, although undocumented, by general practitioners.

Objective: During analysis of a survey on the follow-up of opiate addicts starting substitution therapy with HDB, we attempted to assess the frequency of early drop-outs and identify the contributing factors.

Economic and social effects of high-dose buprenorphine substitution therapy. Six-month results.

The purpose of this study was to analyze the impact of high-dose buprenorphine substitution therapy in opiate-dependent patients in terms of use of psychoactive substances, associated risks, social integration, and the social cost generated by the use of these substances. This was a longitudinal quantitative survey carried out in 1083 patients who were evaluated at three times: at the beginning of substitution therapy (D0), at 6 months and then at 12 months follow up (M6, M12). Data were collected with an anonymous self-administered questionnaire, completed in the presence of an investigating physician.
