two problems with that. first of all, some drugs would be impossible to monopolize. anyone can grow pot in their back yard or basement. the second, and biggest IMO, problem, is that there is too much money invested in keeping the drugs ILLEGAL. all the people who get paid to make up lies about drugs for the government... all the people who have made careers out of putting people in jail for drugs. our prisons are filled with first time non violent drug offenders. PRIVATE prisons that make money off of these people being locked up. cops get money for their "task forces" and similar bullshit. they profit off of it being illegal... the drug test companies, who somehow have convinced the public that everyone needs to be drug tested for every single job out there, and even our our kids in school etc etc. those drug tests cost MONEY. they profit off of it. the pharmaceutical companies who make "marinol" (basically pot in a pill) would lose lots of money if it were legal... it goes on and on. these people are not going to be happy when you start fucking with their bread and butter.
