Controlled Substance and Drug Offenses Attorney

A significant part of the criminal defense practice at the Law Offices of Marc Neff is devoted to the representation of clients facing serious felony and misdemeanor controlled substance charges in the state and federal courts.

The firm’s drug defense litigation practice handles cases ranging from a simple possession to large scale manufacturing and distribution cases. Mr. Neff has represented defendants in some of the area’s largest drug cases. Nationally, he has consulted on cases from Florida to Canada. Prior clients have included doctors and dentists who were charged with improprieties arising out of their medical or dental practices.

Controlled substances are drugs which are regulated by federal and state law. The production, possession, importation, and distribution of these drugs is strictly regulated or outlawed, although many may be dispensed by prescription. The substances are listed in five categories, or schedules, according to their characteristics, and the type and degree of regulation is determined by the category the particular substance is in. The basis for the regulation is to control the danger of addiction, abuse, physical and mental harm, the trafficking by illegal means, and the dangers from actions of those who have used these substances.

The Controlled Substances Act (CSA) Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970 is a combination of numerous laws regulating the manufacture and distribution of narcotics, stimulants, depressants, hallucinogens, anabolic steroids, and chemicals used in the illicit production of controlled substance. It is administered by the Drug Enforcement Administration (DEA). The DEA’s enforcement of the CSA includes investigation and preparation for the prosecution of violators of these laws, on both interstate and international levels.

Marc Neff has over twenty-five years of trial experience in defending these cases. Immediate response and an aggressive approach can often make the difference in the defense of drug cases. The firm utilizes a team of investigators and, where necessary, forensic translators to battle these cases. Additionally, the firm maintains certain international relationships to assist United States citizens facing charges in foreign jurisdictions as well as foreign nationals who may be facing extradition proceedings in the United States.

As in all of our cases, preparation is the key to success. With over twenty-five years experience defending complex controlled substance and money laundering cases, Mr. Neff has the experience, knowledge, and expertise to effectively prepare and litigate these cases.
