support anti-marijuana laws (Rosenthal 2). Another interest group includes the scientists whose marijuana research is funded by the government. If marijuana were legalized, they would lose millions of dollars in research grants intended to prove the detrimental effects of the substance. Two other unrelated and very influential groups are the liquor lobby and pharmaceutical companies. Their spending is usually very secretive and not publicized very much. Legalization of a competing product that can be produced with relative ease by anyone with access to a plot of land would cut deeply into their profits. And the drug companies want control, rather than just a ban, for they know the medicinal benefits of marijuana (Rosenthal 9). Therefore the major reason marijuana still remains illegal is that special interest groups are blocking legislation by extensive lobbying. Clearly it is seen that many people support its use, at least for medical reasons. It is obvious that the current policy for marijuana is not working very efficiently. The government spends billions of dollars every year to stop its use. This leads to the opening of a very extensive black market for marijuana, because the drug is still in high demand. With the black market comes all the crime and violent acts that create a new problem of overcrowding prison populations. In effect, the government does not really solve the marijuana problem; instead it just creates a new one in its place.

This law established criteria for determining which substances should be controlled, mechanisms for reducing the availability of controlled drugs, and a structure of penalties for illegal distribution and possession of controlled drugs (Roffman 4). The criteria for Schedule I substances are: The drug or other substance has a high potential for abuse, the dru...
