Is Drug Possession a Felony or Misdemeanor in San Francisco?
Since California voters passed Proposition 47 in 2014, simple possession of a controlled substance for personal use is almost always a misdemeanor. The five statutes that show up most often in San Francisco arrests:
- Health & Safety Code 11377 — possession of methamphetamine and other Schedule II/III substances. The most common San Francisco drug charge. Up to one year in county jail.
- Health & Safety Code 11350 — possession of cocaine, heroin, prescription pills without a valid prescription. Same maximum.
- Health & Safety Code 11357 — possession of cannabis in a prohibited place or by someone under 21. Recreational adult possession is legal in California, but possession on school grounds, in a vehicle, or by someone underage still triggers this statute.
- Health & Safety Code 11364 — possession of drug paraphernalia. A pipe, a needle, a spoon — charged on its own or stacked on top of a possession count. Up to six months county jail.
- Health & Safety Code 11532 — loitering for the purpose of using or being under the influence of a controlled substance. Used heavily in San Francisco’s open-air drug market enforcement.
For a first offense in San Francisco, jail time on any of these is rare. The fight is about keeping the case off the record.
The exceptions where drugs are still felonies: possession for sale, possession with a firearm (HS 11370.1), or possession with prior serious or violent felony convictions. Those facts change the calculus. Simple personal-use possession does not.
Three Paths That Don't End in a Conviction
1. PC 1001.95 — Misdemeanor Judicial Diversion
Since 2021, a San Francisco judge has the authority to divert most misdemeanor cases — including possession under HS 11377, 11350, 11357, paraphernalia under HS 11364, and loitering under HS 11532 — over the District Attorney's objection. No guilty plea is required. The court tailors the conditions — alternatives to incarceration the lawyer negotiates — over up to 24 months. Complete it, and the case is dismissed. The arrest can then be sealed under PC 851.91. Carve-outs apply — domestic violence and 290-registerable offenses are excluded — but standard drug possession qualifies.
2. PC 1001.36 — Mental Health Diversion
If a qualifying mental health diagnosis contributed to the offense, the defendant may qualify for mental health diversion. This is a more comprehensive track that requires evaluation by a qualified social worker or clinical psychologist. ASH Legal regularly works with social workers funded through BASF-IDA to build the evaluation record. Successful completion dismisses the case entirely. The arrest can be sealed.
3. Suppression Motion — PC 1538.5
If the police found the drugs through an unlawful search — no warrant, no consent, no probable cause — I can file a motion to suppress the evidence. If the motion is granted, the prosecution has no case. The charges get dismissed. Many drug possession cases turn on the legality of the stop or the search; that's where the work begins.
What a Defense Attorney Actually Does
Most clients have never been through this. They imagine a courtroom drama. The real work happens before any of that.
- Read the police report. Was the stop legal? Was the search consensual? Was Miranda triggered? A bad stop is a case-killer.
- Inspect the chain of evidence. Was the substance properly tested? Properly weighed? Properly stored? Crime lab errors happen.
- Push the diversion. Not every prosecutor agrees to PC 1001.95 reflexively. Some need to be pushed — and the judge has authority to grant it over the DA’s objection. That is leverage.
- Build the mental health record — if applicable — with a qualified social worker, so PC 1001.36 becomes a real option, not a long shot.
- Litigate the suppression motion if the search was unlawful. Successful suppression dismantles the case.
Why a Drug Conviction Isn't Just a Drug Conviction

What to Do Right Now
Do not talk to the police. Anything you say is an admission. The right to remain silent is the most important right you have. Use it.
Do not consent to additional searches. If the officer asks to search your phone, your car, your home — say no. Politely. Clearly. On the record.
Do not post about the arrest. Not on Instagram. Not on Snapchat. Not in group chats. Prosecutors use social media as evidence.
Save everything. The citation, the booking paperwork, the names of the officers, anything they handed you. It all matters later.
Call a lawyer before your arraignment. The earlier I’m involved, the more options stay on the table.
