SC Cultivation & Manufacturing — One Plant = Felony

Last verified: May 2026

The Statutory Framework

S.C. Code § 44-53-370(a) makes it unlawful to "manufacture, distribute, dispense, deliver, or purchase ... or possess with the intent to manufacture, distribute, dispense, deliver, or purchase a controlled substance." Marijuana and its concentrated forms are Schedule I controlled substances under § 44-53-190. "Manufacture" is broadly defined; cultivation of cannabis is treated as manufacturing because it produces a controlled substance from precursor materials.

Penalty exposure depends on the quantity (and prior history):

• Cultivation of any plant, 1st offense: felony under § 44-53-370(b)(2); up to 5 years and/or up to $5,000 fine.
• Cultivation, 2nd offense: felony; up to 10 years and/or up to $10,000 fine.
• Cultivation, 3rd or subsequent: felony; 5–20 years and/or up to $20,000 fine.
• 10+ pounds or 100+ plants: trafficking under § 44-53-370(e); mandatory minimums kick in (1–10 yrs at low end; 25 yrs at 100–2,000 lbs / plants).

The "One-Plant Felony"

Unlike most adult-use states — and even some prohibition states with a "personal cultivation" defense or de minimis exception — South Carolina has no statutory home-grow allowance. A South Carolinian who plants a single seed in their backyard is, on those facts alone, manufacturing a Schedule I controlled substance. Prosecutorial discretion may divert some cases to PTI or charge bargaining, but the underlying statutory exposure is felony manufacturing with up to 5 years.

This is significant because most state-level reform conversations begin with a "personal cultivation" or home-grow allowance — an authorization for adults to grow a small number of plants for personal use. SC’s draft Compassionate Care Act (S.53) also bans home cultivation in any future medical program, distinguishing SC from Florida (no home-grow) and from most adult-use states (typically 6 plants per adult). See what S.53 would do.

The 100-Plant Trafficking Trigger

Under § 44-53-370(e), cultivation of 100–1,000 plants triggers the 25-year mandatory minimum trafficking sentence. The plant count is mechanical: the state typically counts every plant, including seedlings and clones, regardless of whether the plant has reached maturity. Defense bar practice in 100-plant cases routinely involves contesting the count (which plants count? are dead plants counted? are clones in propagation trays counted as separate plants?), the chain of custody, and the search authority.

Above 1,000 plants: 25 years mandatory minimum continues; above 10,000 plants: 25–30 years mandatory. See trafficking page.

BHO and Concentrate Manufacturing

Concentrate manufacturing — butane hash oil (BHO) extraction, wax, shatter, distillate, vape-cartridge filling — is treated as a separate Schedule I felony manufacturing offense under § 44-53-370(b)(2). Hashish itself has its own ten-gram simple-possession threshold under § 44-53-370(d)(4), but other concentrates (BHO/wax/shatter) are typically charged under the broader Schedule I framework. Manufacturing exposure is 5 years (1st), 10 years (2nd), 5–20 years (3rd+).

BHO extraction also carries collateral exposure: butane is flammable, and explosions from amateur BHO operations have, in SC and elsewhere, produced separate arson, reckless endangerment, and homicide charges where injuries or deaths result.

School-Zone Enhancement — § 44-53-445

Cultivation or manufacturing within a half-mile of a school, park, or playground triggers the § 44-53-445 enhancement: separate offense, up to 10 years and $10,000. The half-mile zone covers most urbanized SC neighborhoods; for indoor-grow operations in dense Charleston, Columbia, or Greenville residential areas, the enhancement is a near-default add-on.

Hemp and the "Total THC" Question

South Carolina hemp law tracks the federal 2018 Farm Bill: cannabis is "hemp" if delta-9 THC concentration is at or below 0.3% on a dry-weight basis. THCA flower (which converts to delta-9 when heated) sits in a contested space. AG Alan Wilson’s position is that products with significant THCA exceed the 0.3% delta-9 threshold once heated and are therefore unlawful "marijuana" rather than legal "hemp." Solicitor General Robert D. Cook’s September 16, 2024 opinion took a contrary view on hemp-derived delta-9 beverages. Operation Ganjapreneur prosecutors test on a "total THC" theory; SLED lab found 261 of 270 brands "came back hot." See Wilson–Cook conflict page.

Hemp Farming — What Is Authorized

The South Carolina Hemp Farming Act (Act 37 of 2017, amended by Act 14 of 2019) authorizes commercial hemp cultivation by licensed farmers under SCDA oversight. As of 2024, 98 farmers were permitted, planting 40 acres outdoor and operating 62,600 sq ft indoor. Hemp cultivation by an unlicensed grower is treated as marijuana cultivation regardless of the delta-9 content, because the licensing structure is the affirmative authorization. See hemp farming act page.

Federal Cultivation Exposure

Federal cultivation under 21 U.S.C. § 841 carries its own mandatory minimums: 100+ plants = 5-year minimum / 40-year maximum; 1,000+ plants = 10-year minimum / life maximum. U.S. Attorney intake criteria typically pull in the largest indoor-grow operations and outdoor-cartel-affiliated grows. Defendants in 100+ plant SC cases often face simultaneous federal-charging consideration.

Practical Implications for South Carolinians

• There is no SC home-grow exception, even for severely ill patients under Julian’s Law (which authorizes only out-of-state CBD product, not in-state cultivation).
• Even a single seedling is felony exposure.
• Above 100 plants, the case becomes a 25-year mandatory case.
• BHO/concentrate manufacturing produces additional explosion/arson exposure on top of drug-felony charges.
• Federal exposure layers on top of state exposure for any 100+ plant operation.
