The marijuana enforcement division in Colorado, US, is proposing to label edible marijuana products with a new red stop sign in the state.
The new rules come as the regulator works on new guidelines for edible marijuana, which can be baked into cookies or brownies or added to a wide range of products such as sodas, pasta sauces and granolas.
When put into force, the proposed rules would require individual edible marijuana item to carry an octagon stop-sign shape with the letters 'THC' (tetrahydrocannabinol) that indicate marijuana's psychoactive ingredient, The Associated Press reported.
The state is also contemplating plans to impose a ban on the usage of the word 'candy' in edible pot products, including sweets such as suckers or gummy chews.
Additionally, liquid marijuana products will be restricted to be packaged in single-serve packs defined as 10mg of THC.
Smart Colorado's Diane Carlson said: "It's time we have a tool to really let people know there is pot in something."
The latest proposals come after the regulators declined to mark edible pot with a weed-leaf symbol after parents complained the symbol would attract children rather than preventing children from consuming such products.
These rules would also ban premade edible items.
The proposed rules would be put into effect by January to revamp marijuana packaging.
However, the manufacturers have raised concerns that the law, which requires edible to be 'stamped, shaped, coloured or otherwise marked' that is not for consumption by children would be unwieldy when it comes to liquid products or anything apart from hard candies or cookies.
