Hemp and marijuana are the same plant species, Cannabis sativa L. The difference is legal, not botanical.
The federal line
- Hemp is cannabis with no more than 0.3% delta-9 THC by dry weight, a definition set by the 2018 Farm Bill.
- Marijuana is cannabis above that limit. Under federal law it is still a controlled substance, even though many states have legalized it for medical or adult use.
Federal hemp rules were tightened by Congress in late 2025 (counting total THC and limiting intoxicating hemp-derived products), with the change scheduled to take effect in November 2026. Some states have their own, stricter hemp rules too. Check the current federal and state rules before you buy or travel.
What this means on WeedWayz
- CBD and hemp stores sell hemp-derived products. What they can sell depends on state law.
- Dispensaries are licensed by a state cannabis program to sell marijuana to adults 21+ or to registered patients.
- WeedWayz is a directory. We don't sell any of these products.
