Yes, marijuana will become readily available in the US because many states are currently holding a vote on legalization. Once enough states vote yes, the rest of the country will follow. There is no reason for it to be illegal, since science has proven it is not a very harmful drug.
People are finally using common sense when it comes to their views on the medicinal value of marijuana and it will become commonplace once its effects more widely publicized. There is no valid reason to deny this relief to those who suffer from various afflictions, especially since it is so inexpensive to most pharmaceutical drugs. It is also less toxic than many approved medicines. It is only right that the government change its position and embrace the benefits of this as a legitimate means of treating various disorders and diseases.
Colorado is a great example of this. Marijuana has proven to have many medical benefits. It is an untapped market that can be taxed and earn the country extra money. Crime has also gone down immensely in areas where marijuana is legal. It is a matter of time before it is legalized everywhere.
Yes, I do believe that medical marijuana will become readily available at some point. I believe within the next 20 years there will come a point where the benefits of marijuana for patients with certain types of ailments will be better known. At this point it would be foolish for the U.S. government not to make this available to them.
