Shipping Regulations

– It’s Federally illegal to transport cannabis products across state lines, excluding hemp-derived CBD products
– Importing certain materials such as vape batteries and cartridges may be considered Electronic Nicotine Delivery Systems or ENDS under the PACT ACT, and thus may be challenging to ship.
– Intra-state transportation of cannabis products requires that businesses be registered with the state.
– Cannabis must be transported only inside of a vehicle or trailer – cannot be shipped on a plane, even within the state, as federal law supersedes state law

Extra Notes

Label must read medical use only if for medical patients
– No cartoons, no resemblance to candy
– Prop 65 warning
– Must display state- Specific warning regarding dangers of smoking and consuming cannabis & cannabis products. A business wishing to provide a safe harbor warning must meet all applicable requirements of the Article 6 Clear and Reasonable Warnings regulations.
– Must have allergen warning

Warning Label

The symbol must be placed to the left of the text of the warning in a size no smaller than the height of the word “WARNING”.  If the sign, label, or shelf tag for the product is not printed using the color yellow, the symbol may be provided in black and white.  



The universal symbol for cannabis alerts people that the product contains cannabis. It must be on the primary panel of all cannabis goods sold in California. Do not alter the symbol, other than changing the size. It must be at least ½ inch by ½ inch in size.
