Are Shrooms Legal in Vegas? Penalties, Spores, and Federal Risk

No, shrooms are not legal in Vegas. Psilocybin mushrooms are a Schedule I controlled substance under Nevada law, and possessing any amount is a felony. Nevada has no decriminalization ordinance, no medical exception, and no regulated therapy program. The penalties climb sharply with weight, and federal law adds a second layer of exposure on top of the state charges.

How Nevada Classifies Psilocybin

Psilocybin sits in Nevada’s Schedule I, the most restrictive category the state uses. Under NRS 453.166, a substance goes there when it has a high potential for abuse and no accepted medical use in the United States.¹ Psilocybin is listed by name alongside LSD, heroin, and mescaline.²

Federal law matches. Psilocybin has been on the federal Schedule I list under the Controlled Substances Act since 1970.³ There is no state loophole to work around, and no federal carve-out to fall back on.

Penalties for Possession

Every psilocybin possession charge in Nevada is a felony. The category depends on how much you have and whether you have prior drug convictions. NRS 453.336 sets the tiers.¹

Under 14 grams, a first or second offense is a Category E felony carrying 1 to 4 years in prison and a fine up to $5,000. The statute requires the court to defer judgment if the defendant consents, which typically means probation instead of prison. A third or subsequent offense at that weight becomes a Category D felony, still 1 to 4 years but with a fine up to $20,000.

From 14 to under 28 grams, the charge is a Category C felony carrying 1 to 5 years. From 28 to under 42 grams, it’s a Category B felony with 1 to 10 years and a fine up to $50,000. From 42 to under 100 grams, it stays a Category B felony but the prison range jumps to 2 to 15 years.¹

One detail that catches people off guard: the weight is the full weight of the mushroom material, not just the psilocybin content. An ounce of dried mushrooms weighs about 28 grams, which is enough to push a first-time possession case out of Category E and into Category B territory.

The One-Time Break for First-Time Offenders

If you have no prior drug convictions anywhere in the country, Nevada gives you one chance to avoid a permanent felony record. Under NRS 453.3363, a first-time offender who pleads guilty or no contest to a small-quantity possession charge can have the proceedings suspended. Instead of a conviction going on your record, the court places you on probation with conditions that include either a drug education program or, if you have a substance dependency, a treatment and rehabilitation program.⁴

Complete probation successfully and the court dismisses the charges. This is where a lot of first-time psilocybin cases actually end up in Las Vegas. But the offer only comes once. A second offense won’t qualify, and a failed probation puts you back in front of the judge for sentencing.⁴

Selling, Intent to Sell, and Trafficking

Anything that looks like distribution is prosecuted much more aggressively than personal possession. Under NRS 453.321, selling or giving away psilocybin is a Category C felony for a first offense (1 to 5 years). A second offense becomes a Category B felony with 2 to 10 years and a fine up to $20,000. A third or subsequent conviction carries 3 to 15 years and a fine up to $100,000.¹

Actual sale isn’t required. Under NRS 453.337, possession with intent to sell is a Category D felony on a first offense (1 to 4 years), and evidence like scales, baggies, cash, or divided quantities can support the charge even when no transaction took place.

At 100 grams or more, the case becomes trafficking under NRS 453.3385 regardless of whether you intended to sell. From 100 to 399 grams is a Category B felony carrying 2 to 20 years and a fine up to $100,000. At 400 grams or more, it becomes a Category A felony punishable by life with parole eligibility after 10 years, or a fixed 25-year term, plus a fine up to $500,000.¹

Federal Charges Are a Separate Risk

State penalties aren’t the whole picture. Federal law independently criminalizes psilocybin possession. Under 21 U.S.C. § 844, a first federal simple possession conviction carries up to 1 year in prison and a minimum fine of $1,000. A second offense raises the range to 15 days to 2 years with a minimum $2,500 fine. Three or more prior drug convictions push it to 90 days to 3 years and at least $5,000.⁵

Federal charges become the default rather than the exception when psilocybin turns up on federal property. The Las Vegas area contains a lot of it: Lake Mead National Recreation Area, Red Rock Canyon, and the Spring Mountains. Airports are federally controlled space too, which matters if you’re flying in from a state where the rules are looser.³

The Federal Analogue Act reaches further. Under 21 U.S.C. § 813, a substance chemically similar to psilocybin and intended for human consumption is treated as Schedule I even if it isn’t specifically listed. Synthetic analogues and novel tryptamines marketed as “legal” alternatives can still trigger federal prosecution.⁶

What About Spores?

Psilocybin mushroom spores are the one gray area, and it trips people up. Spores don’t contain psilocybin or psilocin, so they aren’t scheduled substances under state or federal law. They’re sold online, usually marketed for microscopy. The moment you germinate them and grow mushrooms that produce psilocybin, you’re manufacturing a Schedule I substance. Buying spores with the intent to cultivate can support charges before any mushrooms actually appear. Prosecutors take that line seriously.

Consequences Beyond the Sentence

A psilocybin conviction reaches well past whatever time or probation the court imposes.

Federal law prohibits anyone convicted of a crime punishable by more than a year in prison from possessing firearms or ammunition. Because every Nevada psilocybin charge is a felony, a conviction ends your gun rights under federal law. The Gun Control Act also bars anyone who is an “unlawful user of” a controlled substance from possessing firearms, and that applies without any conviction at all.⁷

For non-citizens the stakes are worse. A controlled substance conviction generally makes a person deportable and inadmissible under federal immigration law. Even admitting drug use in an immigration interview, without any arrest, can trigger the same consequences. Deferred judgment in criminal court doesn’t shield you here.

Federal employment and security clearances are also affected. A drug felony isn’t an automatic bar to federal work, but agencies weigh the offense, how recent it was, and its relationship to the job.⁸ Clearance applications require full disclosure of drug history, and a Schedule I conviction can derail the process.

Why People Think Shrooms Are Legal

If you’ve heard psilocybin is legal now, you’re thinking of Oregon or Colorado. Oregon built the first regulated psilocybin therapy program. Colorado legalized personal possession and use for adults 21 and older, allowing cultivation in a locked space up to 12 feet by 12 feet and sharing among adults in therapeutic or spiritual contexts, though sales remain prohibited.⁹

Nevada has done none of this. No Nevada city, Las Vegas included, has passed a decriminalization ordinance. No ballot initiative has passed. What’s legal personal conduct in Denver is a felony arrest in Las Vegas.

What Might Change

Nevada is looking at the question. The state legislature convened a Psychedelic Medicines Working Group that produced a report for the 2025 session, exploring whether psilocybin should be rescheduled for therapeutic use. The FDA has also issued draft guidance on clinical trials with psychedelics, including psilocybin.¹⁰

None of that changes what’s on the books. Psilocybin remains fully illegal in Nevada, with no medical exception, no decriminalization buffer, and no therapeutic access program. Anyone possessing mushrooms in Las Vegas is facing state felony charges and, depending on where the arrest happens, potential federal charges on top.
