The Controlled Substance Act (CSA) federally regulates drug schedule classifications. Based on these schedules, the type and amount of drug listed in your criminal charges can affect the severity of your case. The five drug schedules include: Schedule I: Drugs with no currently accepted medical use and a high potential for abuse. Examples include heroin, LSD, marijuana, peyote, and ecstasy. Schedule II: Drugs with a high potential for abuse, with use potentially leading to psychological or physical dependence. Examples of Schedule II drugs are cocaine, methamphetamine, and oxycodone. Schedule III: Drugs with a low to moderate psychological or physical dependence. Examples include Tylenol with codeine and anabolic steroids. Schedule IV: Drugs with low abuse potential and low risk of dependence. Examples are Xanax, Tramadol, and Ativan. Schedule V: Drugs with low abuse potential, often used for antidiarrheal, antitussive, and analgesic purposes. A criminal defense lawyer can review your charges and examine evidence connected with your arrest. A lawyer can also explain the charges against you so that you understand the specific punishments you may face.
