The Chase for a Legal High: Discovering What Arizonans Know About Designer Drugs

Description

This creative project explores the trend of designer/synthetic drug use in Arizona and nationwide. The project serves as "gap research" - bringing to light the problem of limited use statistics

This creative project explores the trend of designer/synthetic drug use in Arizona and nationwide. The project serves as "gap research" - bringing to light the problem of limited use statistics and constantly-changing drug chemical compounds. The project was thoroughly researched using media reports, psychology/drug addiction experts, community education organizers and available healthcare statistics. The results provided not definitive answer other than that more work needs to be done in the area of synthetic drug use. Parents and youth must educate themselves on the dangers of using these "legal" drugs.

Methamphetamine and novel "legal high" methamphetamine mimetics: abuse liability, toxicity, and potential pharmacobehavioral treatments

Globally, addiction to stimulants such as methamphetamine (METH) remains a significant public health problem. Despite decades of research, no approved anti-relapse medications for METH or any illicit stimulant exist, and current treatment approaches suffer from high relapse rates. Recently, synthetic cathinones have also emerged as popular abused stimulants, leading to numerous incidences of toxicity and death. However, contrary to traditional illicit stimulants, very little is known about their addiction potential. Given the high relapse rates and lack of approved medications for METH addiction, chapters 2 and 3 of this dissertation assessed three different glutamate receptor ligands as potential anti-relapse medications following METH intravenous self-administration (IVSA) in rats. In chapters 4 through 7, using both IVSA and intracranial self-stimulation (ICSS) procedures, experiments assessed abuse liability of the popular synthetic cathinones 3,4-Methylenedioxypyrovalerone (MDPV) , methylone, α-pyrrolidinovalerophenone (α-PVP) and 4-methylethylcathinone (4-MEC). Results from these seminal studies suggest that these drugs possess similar abuse potential to traditional illicit stimulants such as METH, cocaine, and 3,4-methylenedioxymethamphetamine (MDMA). Finally, studies outlined in chapter 8 assessed the potential neurotoxic or adverse cognitive effects of METH and MDPV following IVSA procedures for the purpose of identifying potential novel pharmacotherapeutic targets. However, results of these final studies did not reveal neurotoxic or adverse cognitive effects when using similar IVSA procedural parameters that were sufficient for establishing addiction potential, suggesting that these parameters do not allow for sufficient drug intake to produce similar neurotoxicity or cognitive deficits reported in humans. Thus, these models may be inadequate for fully modeling the adverse neural and psychological consequences of stimulant addiction. Together, these studies support the notion for continued research into the abuse liability and toxicity of METH and synthetic cathinones and suggest that refinements to traditional IVSA models are needed for both more effective assessment of potential cognitive and neural deficits induced by these drugs and screening of potentially clinically efficacious pharmacotherapeutics.
