Industry Guide
A high-level overview of the cannabis and hemp industry, including regulation, product categories, market structure, and business economics.
Policy
Cannabis and hemp operate within a layered mix of federal, state, and local regulation. The legal distinction between hemp and cannabis shapes how products are produced, distributed, sold, taxed, and enforced.
That framework continues to evolve as lawmakers, regulators, and courts confront hemp-derived THC products, federal rescheduling debates, enforcement uncertainty, and the widening gap between federal law and state-legal markets.
- Grown In Policy Guide
- Illinois Hemp Regulation
- The Federal Status of Marijuana and the Policy Gap with States
- FDA Regulation of Cannabis and Cannabis-Derived Products, Including Cannabidiol (CBD)
Key policy topics:
- Controlled Substances Act — the federal legal framework that still classifies marijuana as illegal at the national level
- 2018 Farm Bill — the law that federally legalized hemp and established the 0.3% delta-9 THC threshold
- Internal Revenue Code Section 280E — the federal tax rule that limits ordinary business deductions for many cannabis operators
- Federal Legal Consequences of Rescheduling Marijuana — how rescheduling could affect criminal exposure, tax treatment, medical research, business operations, and the tension between federal and state cannabis law
Markets
Cannabis markets vary widely across states. The Midwest offers a useful lens into how different regulatory models shape pricing, competition, licensing, consumer access, and long-term market structure.
Products
Product categories are shaped as much by regulation as by chemistry. The distinction between hemp-derived and cannabis-derived products affects where items can be sold, how they are taxed, who can buy them, and how they are regulated.
Visual Guide
The legal distinction between hemp and cannabis begins with THC concentration under federal law.
Research
Scientific research, institutional infrastructure, and data systems will play a major role in the long-term development of the cannabis industry. Despite rapid market growth, research remains limited by federal restrictions, funding gaps, inconsistent standards, and fragmented data.
