This First edition also includes commentaries, defenses and latest jurisprudence for Violations of R.A. 9165, as amended. This Author believes that if criminality is to be minimized, if not eradicated, the Revised Penal Code must be amended to impose greater penalties for crimes committed by public officers, violations of the fundamental laws of the State, and for it to be an effective deterrent, the death penalty should be reimposed. It is also hoped that the law practitioners and students can use this Book in their advocacy, and in their pursuit of legal excellence.
