Abstract:
This study examines hypotheses and builds models to help clarify the causal connections between drugs and violence outcomes among Mexican-American male gang members. The study uses cross-sectional data of 160 male gang members sampled from 26 gangs in a Southwestern city. A life-history /intensive interview using closed and open-ended questions and a violence risk psychometric test (PFAV) also employed 10 scenario questions to elicit self-produced accounts of the participant's last fight. Gang member participant's ages ranged from 14 to 25 years with a mean age of 18.5 years. The study concludes that drug use interacts with an individual gang member's risk for violence to affect violent behavior outcomes. Furthermore, an important situational variable explaining violent outcomes among respondents scoring high on the violence risk measure was whether the rival was using drugs that resulted in high intoxication levels. The study concludes that drugs have a modulating and mediating influence on violence that is conditioned by situational and individual level variables among members of these adolescent street gangs.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
