His reversal is a good reminder that our ultimate goal is to be rid of an entire health care system by which we are ruled by health care technocrats, bureaucrats, and politicians.
The mainstream perspective is that experts and technocrats should establish what the best medical practices are and then bureaucrats should enforce those practices on everyone. Practices deemed suboptimal, unproven, or potentially dangerous should be prohibited by politicians and the prohibition enforced by bureaucrats. This is a one-size-fits-all system with the state determining what fits and what does not.
Never shy about intervention, the government has provided monopoly privileges for doctors through licensing, for drug companies through patents and trade restrictions, and for hospitals, who can prevent competitors from entering their market through “certificate of need” requirements. The combination of monopoly suppliers and subsidized consumers is the primary reason for this era of rising medical costs and falling health care outcomes.
With the prevailing attitudes and policies toward marijuana, it should not be surprising to learn that almost all of the research funded by government has been to determine if marijuana causes medical problems and not of the medical benefits of its use. Almost all the negative health results found in older studies have since been found to be false or irrelevant to the real world. In contrast, positive medical benefits continue to be found without producing any significant side effects.
