The impact of gamma hydroxybutyrate (GHB) legal restrictions on patterns of use: Results from an International Survey

Abstract

AIMS: To conduct an Internet-based survey of GHB use, identifying differences by respondent residence. METHODS: We recruited GHB-knowledgeable persons via "social networking Internet sites." Individuals (n=314) or groups (n=66) were approached based on GHB-use testimonials. DATA COLLECTED: location, use, reason for cessation (if applicable). FINDINGS: We recruited 155 GHB users. U.S. respondents (53 of 70; 76%) compared to non-U.S. respondents (38 of 85; 45%) were older and more highly educated (p<0.05) but manifest a 3-fold greater adjusted odds of GHB cessation (Odds Ratio [OR] 3.1; 95% CI 1.4-6.9; p < 0.05). Of the 80 respondents stating reason for cessation, 36 (45%) cited legal risk, price, or access; 44 (55%) cited health or related concerns. U.S. compared to non-U.S. respondents more frequently invoked legal and related concerns (OR 2.5; 95% CI 0.99-6.3; p=0.05). In a nested analysis, narrowly stated legal (n=4/5 U.S.) versus health (n=6/18 U.S.) reasons differed by location (p=0.048, one-tailed). CONCLUSIONS: In the U.S., where GHB has stricter legal penalties, GHB cessation is more likely, with legal and related reasons more commonly invoked for cessation. These findings support a link between declining U.S. GHB abuse and more stringent restrictions; although other un-assessed factors may also explain this association.
