Heroin Crimes

Heroin is an illegal and highly addictive drug made from morphine. It’s a part of a class of substances called opioids, which also include prescription pain killers such as hydrocodone, codeine, and oxycodone. Although many people who utilize the drug feel “high” and relaxed, the substance is known to cause a high level of a dependency. If a person uses heroin often, it can develop into an addiction.

According to the National Vital Statistics System of the Centers for Disease Control and Prevention (CDC), 19.8% of drug overdose deaths in 2019 involved heroin. That is why a conviction for possession of heroin is very serious and punishable by up to 99 years in prison depending on the number of grams a person secures. If you were charged with possession of heroin in Texas, it’s best to contact an experienced criminal defense attorney to represent you.

What is a Controlled Scheduled Drug?

Controlled substances are illegal drugs recognized by the Controlled Substances Act (CSA) in the United States. These drugs also include unlawfully obtained prescription medicine such as Vicodin or Percocet. According to Chapter 481 of Texas Penal Code, a “controlled substance” is defined as a substance including a drug, an adulterant, and a dilutant, listed in Schedules I through V. The Controlled Substances Act outlines the drugs into these five schedules according to the highest potential for abuse. The substances with the highest abuse potential are placed in Schedule I, and those with the lowest are in Schedule V.

  • Schedule I – These drugs contain a high risk of chemical dependency. Many have serious long and short-term effects and therefore are not utilized in the medical field. Some examples are heroin, marijuana, lysergic acid diethylamide (LSD), marijuana (cannabis), and 3,4-methylenedioxymethamphetamine (ecstasy)
  • Schedule II – Schedule II lists drugs that have a high abuse risk, with use potentially leading to severe psychological or physical dependence. These substances have an accepted medical purpose in some circumstances. Schedule II drugs include cocaine, methadone, morphine, Demerol, and methamphetamine.
  • Schedule III – Substances under this schedule have a moderate to low potential for psychological and physical dependence. Some examples of Schedule III drugs include ketamine, anabolic steroids, testosterone, and Tylenol with codeine
  • Schedule IV – These substances have a low potential for abuse and low risk of dependence. Some examples include Ativan, Darvocet, Talwin, Tramadol, and Soma.
  • Schedule V – Schedule V substances carry a low potential for abuse in comparison to drugs listed in Schedule IV. They consist primarily of preparations containing limited quantities of specific narcotics. Some examples of Schedule IV drugs include Lomotil, Motofen, Lyrica, and Parepectolin.

Certain factors are considered in determining the category of each drug. According to Section 201 (c), [21 U.S.C. § 811 (c)] of the CSA, these factors are as follows:

  • The drug’s potential for abuse.
  • Scientific evidence of the substance’s pharmacological effect.
  • The state of current scientific knowledge regarding the drug or other substance.
  • The drug’s history and current pattern of abuse.
  • The scope, duration, and significance of abuse.
  • What, if any, risk there is to the public health.
  • The drug’s psychic or physiological dependence liability.
  • Whether the substance is an immediate precursor of a substance already controlled under this subchapter.
