LSD Possession Laws and Penalties in Arizona

Updated September 2026: LSD remains illegal to possess without authorization in Arizona. Arizona classifies LSD, or lysergic acid diethylamide, as a “dangerous drug.” This is a statutory classification used by Arizona law for LSD and numerous other controlled substances.

Possession of LSD is generally a felony in Arizona, although probation may be available in qualifying personal-possession cases. Arizona also establishes a specific statutory threshold for LSD, but exceeding that threshold does not automatically mean that someone possessed LSD for sale.

How Does Arizona Classify LSD?

LSD is specifically included in Arizona's definition of a dangerous drug under A.R.S. § 13-3401.

The term “dangerous drug” is a legal classification. Arizona uses it for a broad group of controlled substances that includes LSD, MDMA, MDA, methamphetamine, certain prescription drugs and numerous psychedelic and designer substances.

Arizona separately classifies substances such as heroin and cocaine as narcotic drugs, which are governed by different provisions of Arizona's drug laws.

Is LSD Possession a Felony in Arizona?

Yes. Under A.R.S. § 13-3407, knowingly possessing or using a dangerous drug is generally a Class 4 felony.

LSD is treated somewhat differently from many other dangerous drugs when it comes to reducing a first possession offense. Arizona law allows certain first-time dangerous-drug possession cases to be designated as a Class 1 misdemeanor or left undesignated while the defendant completes probation.

However, LSD is specifically excluded from that provision. The statute lists lysergic acid diethylamide along with methamphetamine, amphetamine and PCP as drugs for which that particular first-offense misdemeanor or undesignated treatment is unavailable.

That distinction makes it important not to assume that an LSD possession case will be handled exactly like an MDMA or other dangerous-drug possession case.

Can You Receive Probation for LSD Possession?

The fact that LSD is excluded from the special misdemeanor-designation provision does not necessarily mean that a person convicted of simple LSD possession must go to prison.

A.R.S. § 13-3407 separately provides probation eligibility for qualifying convictions involving possession or use of dangerous drugs when the defendant does not have a disqualifying criminal history or another circumstance that makes the person ineligible for probation.

Arizona also has provisions addressing probation and treatment for qualifying personal drug-possession offenses. Because the interaction between these statutes and a defendant's criminal history can be complicated, the consequences should be evaluated based on the specific case.

What Is the Statutory Threshold for LSD in Arizona?

Arizona establishes a specific statutory threshold for LSD in A.R.S. § 13-3401.

The current threshold is:

• One-half milliliter of LSD in liquid form; or
• 50 dosage units when the LSD is on blotter.

The threshold is important, but it is frequently misunderstood. Possessing 50 or more blotter dosage units does not automatically establish possession for sale, nor does crossing the threshold automatically change a personal-possession charge into a sale charge.

Instead, the statutory threshold affects sentencing and probation eligibility for certain offenses identified in A.R.S. § 13-3407, including possession for sale, administering a dangerous drug to another person, and transporting or selling a dangerous drug.

Possession of LSD for Sale

Arizona treats possession of LSD for sale considerably more seriously than possession for personal use. Knowingly possessing a dangerous drug for sale is a Class 2 felony under A.R.S. § 13-3407.

If the amount involved equals or exceeds Arizona's statutory threshold, a person convicted of possession for sale is subject to the threshold provisions of § 13-3407, which restrict eligibility for suspension of sentence, probation and certain forms of release.

Quantity can be evidence in a possession-for-sale case, but the threshold itself does not automatically prove an intent to sell. The prosecution must establish the elements of the offense charged.

Selling or Transporting LSD in Arizona

Arizona law also prohibits transporting a dangerous drug for sale, importing it into the state, selling it, transferring it or offering to do any of those things. These offenses are generally classified as Class 2 felonies.

The statutory threshold becomes especially significant when a defendant is convicted of one of the offenses specifically covered by Arizona's threshold provisions.

Other Consequences of an LSD Conviction

A conviction under A.R.S. § 13-3407 can carry financial and other consequences in addition to incarceration or probation.

The statute requires a person convicted under § 13-3407 to pay a fine of at least $1,000 or three times the value of the dangerous drugs involved, whichever is greater, subject to the maximum fine authorized by Arizona law.

When probation is granted under § 13-3407, Arizona law also requires drug testing and at least 360 hours of community restitution as conditions of probation.

What If the LSD Was on Blotter Paper?

Arizona law specifically accounts for LSD distributed on blotter paper. For purposes of the statutory threshold, 50 blotter dosage units constitute the threshold amount.

The statute also contains special language concerning mixtures or substances containing LSD. Depending on the circumstances, Arizona law looks to the greater offense determined by the entire mixture or substance or by the number of blotter dosage units.

This makes LSD different from many controlled substances for which the statutory threshold is simply expressed as a weight in grams.

Possible Defenses in an LSD Possession Case

A charge is not the same thing as a conviction. The available defenses depend on the evidence and circumstances of the individual case.

One issue may be whether the prosecution can establish knowing possession. The fact that LSD was discovered in a home, vehicle or other location does not necessarily establish that every person present knowingly possessed it.

Search and seizure issues can also be important. The Fourth Amendment protects against unreasonable searches and seizures. Depending on how the evidence was discovered, a defense attorney may examine whether police had lawful grounds for a traffic stop, whether a search was permissible, whether consent was valid or whether a search warrant was legally sufficient.

The identity of the substance may also matter. Modern psychedelic and designer drugs include numerous substances sold on blotter or in forms that may resemble LSD. The prosecution still has to establish that the substance involved in the case is the controlled substance alleged.

If you have been arrested or charged with LSD possession in Tucson or elsewhere in Southern Arizona, the amount allegedly possessed, how the substance was discovered, your criminal history and the specific offense alleged can all affect the potential consequences.
