Despite laws against it, 'Moonshine' is still brewed and tobacco still gets laced with other drugs so your claim that voting "NO" is going to open the door to illicit activities, which BTW already occur, is just a 'straw-man' argument.I’m confused:
With a “Yes” vote we change the laws to what is added. Just like alcohol and tobacco
With a “No” vote we have no control what the drug dealers can keep lacing any substances they want Methamphetamine, LSD, Heroin, Cocaine, Antifreeze, Embalming fluid, Fuels, and much more...
