HS 11350 Ready to Work for YOU


California Health and Safety Code 11350

Possessing controlled substances without a prescription is a crime in California. That crime became less serious after the passage of Proposition 47 but a conviction still has significant consequences.

What The Government Must Prove

  • unlawfully possessed a controlled substance;
  • knew of its presence;
  • knew that was a controlled substance; and
  • possessed a usable amount.

A controlled substance is a regulated drug that has been placed on a schedule of controlled substances by State of California. Cocaine and heroin are examples of controlled substances. Section 11350 applies to many drugs while other drug possession offenses are criminalized in other sections of the Health and Safety Code. Marijuana is governed by a different set of laws.

Unlawful Possession Of A Controlled Substance


The phrase “knew of its presence” protects people who possess a drug inadvertently. If someone left cocaine in your car and you did not know it was there, you did not violate section 11350. If you know that a substance is in your possession but do not know it is a controlled substance, you are not violating the law.

On the other hand, you do not need to know the specific nature of the controlled substance. If you know the drug is a controlled substance but believe it to be cocaine and it turns out to be heroin, you have still violated section 11350.

Usable amount

The requirement that possession must be of a “usable amount” is intended to protect you from prosecution if you are found with a baggie that has trace amounts of the drug. “Usable” does not mean “enough to get you high” but it does mean “enough to use.”

Understanding “Possession”

Section 11350 is intended to criminalize possession for personal use, although the government is not required to prove that you intended to use the drug. It is enough to prove that you possessed it.

There are three ways to possess a controlled substance. The way in which you are accused of possessing the drug may have an impact on the defenses you can raise in your case.

Actual possession

Actual possession means that you either had the drug on your person or that you exercised direct physical control of the drug. For instance, if you place the drug in the glove compartment of a car you are driving, you are in actual possession of the drug.

Constructive possession

Constructive possession means that you had the right to control the drug even if it was not in your actual possession. For example, if you gave the drug to a friend to hold for you and were entitled to have the drug returned upon request, you constructively possessed the drug.

Joint possession

Joint possession means that the drug was possessed by two or more people at the same time. For example, if you and your friend pool your money to buy a quantity of drugs that you intend to share, you are jointly possessing those drugs.

Penalties For Possession Of A Controlled Substance

After November 4, 2014, Proposition 47 made the possession of controlled substance a misdemeanor. The amount of jail time for this drug crime is now one year.

The revision of the law made by Proposition 47 applies to controlled substances criminalized by section 11350 and to other controlled substances, including methamphetamine, that are criminalized by other sections of California law. The only exceptions apply to possession by certain offenders with past convictions for a narrow range of violent offenses and to possession by people who are required to register as sex offenders.

Proposition 47 gives individuals accused of possessing illicit drugs more options than they had under the prior law. Misdemeanor charges allow those who are accused of the crime to seek drug diversion as an alternative to a jail sentence or probation. Since the purpose of Proposition 47 is to channel persons who possess drugs into treatment rather than prison, prosecutors and courts should now be more receptive to the argument that treatment, not punishment, is the best outcome.

Any drug conviction carries the potential for additional consequences. Drug convictions can make it more difficult to obtain certain jobs, to enlist in the military, or to obtain professional licenses and permits. The change in the law is helpful but it does not mean that a California drug charge should not be taken seriously. You should always contact an attorney to find out whether a conviction can be avoided in your case.

Defenses To The Charge You Should Consider

  • I had a valid prescription (or the prosecution cannot prove beyond a reasonable doubt that I did not have a prescription).
  • The drugs were planted by someone with a grudge against me. I did not know they were there.
  • The drugs were left in my house or car by someone else. I did not know they were there.
  • I did not know that the package someone gave me contained a controlled substance.
  • I had no drugs on my person. The witness who claims the drugs were mine is lying to protect himself or someone else.
  • I was trying to buy a controlled substance but the sale was never completed so I did not actually possess it.
  • I was near some people who were in possession of controlled substances but I had no right to use or control the drugs.
  • The substance was not a controlled substance.
  • Whether or not I committed the crime, the evidence cannot be used against me because it was obtained by means of an illegal search or seizure.

  • "Thank You Randy Collins"
    I utilized Mr. Collins services to fight a drug case, which could have ended my career. Mr. Collins was not only very knowledgeable regarding my rights, but also handled my case with the most professionalism that I have yet to experience. His staff was also very friendly and efficient when having any doubts or concerns. At the end my drug case was dropped, I was able to continue my career.
  • "Always Helped Me Understand"
    My son had gotten into some trouble, so thankfully we found Mr. Collins and his paralegal Chris. Every time I called the office, Chris or Mr. Collins guided me through every step and always helped me understand. The legal system is very complicated! But with their assistance and expertise, I couldn't be happier with the outcome of my son's case.
  • "Case Dismissed"
    Case dismissed! I got my girlfriend an attorney to help clear up a warrant she had as well as an outstanding case. The warrant was three years old and she skipped out on court. Randy got case dismissed and warrant is now gone. Only took him one week to accomplish this! Thanks for your help Randy Collins!

    Randy before I call him a professional honest lawyer, he is a human being person and sample of pure lawful person, he won’t do business through your case, he help you before even be your lawyer, with no contract!!! Wow I have never seen a lawyer as honest as him. He left me speechless about his prediction for my case, without charging me. He tells what you need to know with no charge. He was like an angel when I needed him. I couldn’t afford even his advice, but he gave me free information when nobody did . I won’t forget your help. Dear Randy I just was watching my pictures and saw your business card, I don’t remember who introduced you to me. But just wanted to say thank you. We need more lawyers like you.

  • "It Was a Welcome and Uplifting Experience"
    I called to inquire about a case I was facing, this was one of the many attorneys I was speaking with during a free consult about my next steps. The future was looking more and more alarming as the implications of what I was facing were becoming clear. Halfway through explaining my situation, he interrupted me and asked some basic information, put me on hold for one second and came back telling me he had called around and found out that my case was not proceeding. Four other attorneys I had spoken to did not do this, and in fact had used scare tactics and worst case scenarios to try and hard sell me into signing a retainer. (unfortunately, the evening before I HAD with another attorney signed a retainer but that's for another review) Although I did not need to retain the services of this office, I believe that single action speaks worlds about the integrity, helpfulness, intelligence and capabilities of this office. In a world that is so difficult for the uninitiated, such as the legal system, it seems people are taking advantage of you at every turn. It was a welcome and uplifting experience to see the opposite of that with this law office and I am so grateful I was able to find them and know I could call them if anything were to ever happen to me later in life and know I could trust this team.

  • "Easy Communication and Genuine Care"
    I called Randy's office essentially in a panic looking for help for my infant daughter and I in a very difficult case. He and his staff immediately consulted with me, and ultimately resolved my case in the most direct and quickest manner possible. I could not be more grateful or complimentary of how Randy handled my case, as well as the easy communication and genuine care for my well-being. I could not recommend Randy more.
