Marijuana dispensaries have lost the political battle.
Drug stores have been around to sell medicines and sundries with state-licensed pharmacists for years. Government control already exists for these businesses. It seems only logical that the state should develop a system to provide the medical marijuana to legitimate patients through legitimate pharmacies and licensed pharmacists.
It is only a special interest industry that favors a completely segregated business model. The benefits of a special pot dispensary law are primarily for that one specific industry. That industry has been illicit and illegal. Patients need a stable, secure and legal system to obtain medications of any kind.
To legalize marijuana use by medically needy patients, simply make sales subject to all other pharmaceutical product laws, sold only in licensed drug stores by licensed pharmacists.
