The IQ of a piece of toast? It's probably pretty close to mine.

It dosent matter if it has medical uses or not, people should still be able to use it without a doctors prescription. Even if marijuana is legal for medical use it's still illegal for the general public. How many people are really going to need marijuana for the specific medical conditions it is prescribed for? Not many. And Most people don't have time to fuck around going to court when they get caught with a little weed.
