A state Senate committee that visited Colorado to learn about recreational marijuana is warning that Massachusetts may not be prepared for legalization.

In a report released today, the panel recommends steps be taken should voters approve a likely November ballot question that would allow the recreational use and possession of up to an ounce of marijuana for those 21 and older.

The report takes no official stand on legalization but says taxes included in the plan would likely fall short of covering regulatory and social costs attached to legalization. It also outlines public safety concerns including the likelihood that a black market for marijuana will persist even if the drug is sold legally.

The panel spent time in January visiting Colorado, one of four states that allow recreational pot use. (Associated Press)
