HEMP Derived

In the U.S., “legal THC” usually means hemp-derived cannabinoids that are federally legal under the 2018 Farm Bill (≤ 0.3% Delta-9 THC by dry weight).

Common Legal (Hemp-Derived) THC Forms

Delta-8 THC

• Mild psychoactive effects
• Often described as calmer than Delta-9
• Legal federally, restricted or banned in some states
• 
  

Delta-10 THC

• Lighter, more uplifting effects
• Less potent than Delta-8/Delta-9
• Also state-dependent

THC-A (Tetrahydrocannabinolic Acid)

• Non-psychoactive in raw form
• Converts to Delta-9 THC when heated (smoked/vaped)
• Popular in flower, vapes, concentrates
• Legal if hemp-derived and Delta-9 stays under 0.3% by dry weight

THC-O (THC-O Acetate)

• Semi-synthetic cannabinoid
• Stronger, slower-onset effects
• More legally risky; banned or restricted in many states

HHC (Hexahydrocannabinol)

• THC-like effects, often described as smoother
• Chemically altered from hemp cannabinoids
• Legal federally, state restrictions vary
• 
  
• Delta-9 THC (Hemp-Derived)

• Same molecule as marijuana THC
• Legal only if derived from hemp and ≤ 0.3% by dry weight
• Common in gummies (because weight allows compliance)

THCP (Tetrahydrocannabiphorol)

• Extremely potent — studies suggest it may bind to CB1 receptors up to 30× stronger than Delta-9 THC
• Psychoactive — effects can be intense even at very low doses
• Longer-lasting effects compared to Delta-9 for many users
