Psilocybin mushrooms are not legal in Indiana. State law classifies psilocybin and psilocyn as Schedule I controlled substances, the same category as heroin and LSD, with no exception for personal, spiritual, or therapeutic use. Possession starts as a Class A misdemeanor and climbs to a felony when certain aggravating factors are present, while growing or selling mushrooms is charged as dealing and carries far heavier penalties tied to weight.
Why Psilocybin Is Illegal in Indiana
Indiana Code 35-48-2-4 lists psilocybin and psilocyn (the compound your body converts psilocybin into) as Schedule I hallucinogenic substances.1Indiana General Assembly. Indiana Code 35-48-2-4 – Schedule I Schedule I means the state treats the substance as having high abuse potential and no accepted medical use. The classification covers the mushroom in every form: fresh, dried, ground into powder, or baked into food. There is no small-quantity exception and no personal-use carve-out.
Federal law reaches the same result. Under 21 U.S.C. § 812, psilocybin is a Schedule I controlled substance nationwide.2Office of the Law Revision Counsel. 21 USC 812 – Schedules of Controlled Substances On federal land inside Indiana, such as a national park or military installation, federal charges can apply independently of state law. Federal prosecution is uncommon for simple possession but becomes a real risk when the case involves interstate activity or federal property.
Penalties for Possession
Under Indiana Code 35-48-4-7, knowingly possessing a Schedule I substance like psilocybin without a valid prescription is a Class A misdemeanor as the base offense.3Indiana General Assembly. Indiana Code 35-48-4-7 – Possession of a Controlled Substance A Class A misdemeanor carries up to one year in jail and a fine of up to $5,000.4Indiana General Assembly. Indiana Code 35-50-3-2 – Class A Misdemeanor
The charge becomes a Level 6 felony when an enhancing circumstance is present, punishable by six months to two and a half years in prison and a fine of up to $10,000.5Indiana General Assembly. Indiana Code 35-50-2-7 – Level 6 Felony The gap between a misdemeanor and a felony is enormous for the rest of your life, so what triggers the bump matters.
Any of these circumstances can push a possession charge from misdemeanor to felony:
- A prior conviction for dealing a controlled substance other than marijuana or salvia.
- Possessing a firearm during the offense.
- Committing the offense within 500 feet of a school when children were reasonably expected to be there.
- Committing the offense in a public park when children were reasonably expected to be there.
- Delivering or financing delivery to someone under 18 who is at least three years younger than you.
- Committing the offense in the physical presence of a child under 18, knowing the child could see or hear it.
- Committing the offense on the grounds of a prison or juvenile detention facility.
- Committing the offense within 100 feet of a substance abuse treatment program, recovery meeting, or similar facility.
The school-proximity threshold is 500 feet, not the 1,000 feet some sources report.
Penalties for Dealing and Growing
Indiana treats dealing as one broad offense that covers delivery, manufacturing, financing either activity, or possessing psilocybin with intent to do any of those things. The felony level depends mainly on weight, with an enhancing circumstance moving each tier up by one.6Indiana General Assembly. Indiana Code 35-48-4-2 – Dealing in a Schedule I, II, or III Controlled Substance
- Level 6 felony: Less than one gram with no enhancing circumstance. Six months to two and a half years in prison, up to $10,000 fine.5Indiana General Assembly. Indiana Code 35-50-2-7 – Level 6 Felony
- Level 5 felony: One to five grams, or under one gram with an enhancing circumstance. One to six years, up to $10,000 fine.7Indiana General Assembly. Indiana Code 35-50-2-6 – Level 5 Felony
- Level 4 felony: Five to ten grams, or one to five grams with an enhancing circumstance. Two to twelve years, up to $10,000 fine.8Indiana General Assembly. Indiana Code 35-50-2-5.5 – Level 4 Felony
- Level 3 felony: Ten to twenty-eight grams, or five to ten grams with an enhancing circumstance. Three to sixteen years, up to $10,000 fine.9Indiana General Assembly. Indiana Code 35-50-2-5 – Level 3 Felony
- Level 2 felony: Twenty-eight grams or more, or ten to twenty-eight grams with an enhancing circumstance. Ten to thirty years, up to $10,000 fine.10Indiana General Assembly. Indiana Code 35-50-2-4.5 – Level 2 Felony
Growing psilocybin mushrooms is manufacturing under the same statute. That means cultivation is charged as dealing, and prosecutors don’t have to prove you sold anything. Grow equipment, spore syringes paired with substrate, and mature mushrooms can all support a manufacturing charge. Tier depends on the weight of the mushrooms, not the number of them.6Indiana General Assembly. Indiana Code 35-48-4-2 – Dealing in a Schedule I, II, or III Controlled Substance
Are Mushroom Spores Legal
Psilocybin spores sit in a gray area. The spores themselves do not contain psilocybin or psilocyn, so they are not technically a Schedule I substance, and some online vendors sell them as microscopy specimens. Germinating them to grow mushrooms crosses the line into manufacturing a controlled substance, and possessing spores alongside cultivation supplies can support an intent-to-manufacture charge. Indiana has no statute that explicitly legalizes spore possession for research, so the real-world risk depends heavily on what else is found with them.
Amanita Muscaria Is a Different Story
Amanita muscaria, the red-capped mushroom with white spots, is not a controlled substance in Indiana. Its psychoactive compounds, muscimol and ibotenic acid, are chemically distinct from psilocybin and do not appear on any state or federal controlled substance schedule. Products containing Amanita muscaria, including gummies, chocolates, and extracts, are sold legally in the state.
Legal is not the same as safe. In December 2024 the FDA issued a warning stating that Amanita muscaria and its constituents are not authorized for use in food, do not meet the Generally Recognized As Safe (GRAS) standard, and are classified as unapproved food additives.11U.S. Food and Drug Administration. FDA Alerts Industry and Consumers about the Use of Amanita Muscaria or its Constituents in Food The FDA’s 2012 “Bad Bug Book” identifies these compounds as toxic agents that cause poisoning after ingestion, and the agency recommends avoiding foods containing them. Products marketed as “legal psychedelics” or “mushroom edibles” made from Amanita muscaria fall within that warning.
Where Indiana Is Headed on Psilocybin
Indiana has not decriminalized psilocybin or created any therapeutic access program. The state has taken one step toward studying it, though. In March 2024 Governor Eric Holcomb signed House Enrolled Act 1259 into law (Public Law 152), which creates a therapeutic psilocybin research fund administered by the Division of Mental Health and Addiction. The fund provides grants to Indiana research institutions studying psilocybin as a treatment for mental health and other medical conditions, and grantees must conduct clinical studies and report findings to the interim study committee on public health.12Indiana General Assembly. House Bill 1259 – Health Care Matters
That puts Indiana among a growing group of states looking at psychedelic therapy; the Healing Advocacy Fund counts at least 28 states that have introduced some form of psilocybin-access legislation.13Healing Advocacy Fund. Over 28 States Have Introduced Legislation for Psilocybin Access Indiana’s approach is conservative compared with Oregon and Colorado, which have built regulated therapeutic access programs. For now, the legal answer in Indiana is unchanged: psilocybin mushrooms remain a Schedule I substance, and possessing, growing, or selling them carries real criminal exposure.
