Understanding Drug Crimes in Arizona
Drug crimes under the Arizona Revised Statutes (A.R.S.) criminal code include:
- Drug Possession
- Drug Distribution
- Drug Trafficking
- Drug Manufacturing
- Selling Drugs
- Growing Drugs
In Tucson, the consequences for dangerous drug crimes can be severe, potentially including fines, a criminal record, and incarceration. The severity of the penalties often depends on the type and quantity of the drug involved, as well as the specific charges, such as drug possession, trafficking, or manufacturing. Consulting with one of our Tucson criminal defense attorneys can help you minimize the impact these charges will have on your life, and maybe get them thrown out altogether.

Potential Strategies for Drug Cases
Although drug crimes are considered victimless, the potential sentences for convictions are harsh. Our drug crimes lawyers in Tucson can use a variety of defense strategies to lessen your sentence or prove your innocence, such as:
1. Challenging Searches and Seizures
It is your Fourth Amendment right to be protected from unreasonable searches by law enforcement. However, officers sometimes make civilians believe they have the right to perform searches of a person, vehicle, or home without a warrant or probable cause. Our criminal defense attorneys can question the legality of searches and seizures to get any evidence found during the search thrown out.
2. Challenging Evidence
In drug cases, the burden of proof lies heavily on the prosecution. Our criminal defense lawyers at St. Louis Huffman Law will challenge the prosecution’s evidence at every step of the proceedings. We can bring into question how the evidence of the drug crime was stored, who had access to the evidence, whether there were opportunities to contaminate it, if there were inaccuracies during drug testing, and other factors.
3. Demonstrating Unreliability
In some cases, government witnesses used by the prosecution are not reliable or credible. For example, a neighbor may claim that they saw a car pull up to your house, you hand the driver money, they hand you a controlled substance in return, and then saw the car drive away. This eyewitness testimony may not prove that a crime occurred. Our criminal defense attorneys can cast doubt on the reliability of witnesses or present evidence that contradicts what they say.

Drug Diversion Programs An Alternative Sentencing Option for Drug Crimes
Our Tucson attorneys will advise you whether to fight your drug charges pretrial or at trial. However, you may have the option of resolving your case by entering a drug diversion program. The Arizona drug diversion program was established to help drug-dependent defendants get the help they need and avoid incarceration through treatment and education. If this is your first drug offense, you may be a candidate for a drug diversion program.
Which Drugs Are Illegal?

Controlled Substances
Controlled substances are drugs that are tightly controlled by the government because they can be abused or cause addiction. They are illegal under most circumstances. The list of illegal drugs that are considered controlled substances includes:
- Heroin
- Cocaine
- Methamphetamine
- LSD
- Ecstasy
- Peyote
Prescription Medication
Drug crimes involving legal and prescription drugs have become increasingly common. Possession of a medication that is legal for a patient’s use may result in incarceration if the drug is transferred to another person. Prescription drugs included in this rule include:
- Adderall
- Oxycodone
- OxyContin
- Xanax
- Valium
- Morphine
You can also be charged for possessing or using prescription medications obtained through legitimate prescriptions under some circumstances. Additionally, under Arizona’s strict DUI laws, you can be arrested for driving under the influence of legally prescribed drugs.

Recreational Marijuana Laws What You Need to Know
In 2020, Arizona voters passed a referendum to make recreational marijuana legal to possess, use, and cultivate for those 21 and older. However, there are still some restrictions:
- You're only allowed to possess up to one ounce of marijuana or up to five grams of concentrate.
- Like driving under the influence of alcohol, driving under the influence of marijuana is illegal.
- It remains illegal for anyone under the age of 21 to possess or use marijuana.
- It's illegal to distribute marijuana to anyone under the age of 21.
- The use of marijuana in public is classified as a petty offense.
Our Testimonials
“I was recommended to the firm by a friend & police officer who said this was the firm to choose. I consulted and eventually hired Ryan Huffman after our initial meeting. He was great through the year and a half as my case went on, taking his time to explain any and all questions I had. He was also wonderful in his demeanor and handled my nerves and anxiety about my case without judgment… He was great at finding many discrepancies from the prosecution and arresting officers, which in turn greatly benefitted me and helped prove I was not at fault... So thankful to have him there to win my case!”
