On the heels of its successful effort to allow medical marijuana dispensaries, the Rhode Island Senate has voted to launch a comprehensive study of marijuana laws in general. They'll seek to answer these questions, among others:

Whether and to what extent Rhode Island youth have access to marijuana despite current laws prohibiting its use;  

Whether adults' use of marijuana has decreased since marijuana became illegal in Rhode Island in 1918;  
 
Whether the current system of marijuana prohibition has created violence in the state of Rhode Island against users or among those who sell marijuana;  
 
Whether the proceeds from the sales of marijuana are funding organized crime, including drug cartels;

The costs associated with the current policies prohibiting marijuana sales and possession, including law enforcement, judicial, public defender, and corrections costs;

Whether there have been cases of corruption related to marijuana law enforcement;

The experience of individuals and families sentenced for violating marijuana laws;

The experience of states and European countries, such as California, Massachusetts and the Netherlands, which have decriminalized the sale and use of marijuana;

Hmm, I think I can tackle this one: Yes, No, Yes, Yes, Enormous, You don't even want to know, Heartbreaking, Impressive.

This is yet another superb effort from RI legislators and it really sets the standard for how public representatives ought to be examining these laws. These are central questions that, if answered honestly, will drive a stake through the heart of marijuana prohibition once and for all.
