Could you have your wife sign over all her firearms/ammo? Then get a steel gun cabinet and ammo cabinet. I would then put all firearms/ammo in them. You keep the only key. I personally, don't care about the use of medical cannabis, for medical reasons. Issued under a doctors care of course. I think cannabis use for personal consumption has a few issues, its not like alcohol. I'm also concerned about what will be next, people are already want stronger stuff to be made legal.
You mean in the sense that unlike alcohol it doesn't kill ~80,000 people annually?
Alcohol and nicotine should be illegal. By that I mean, if the standard is what is "dangerous" and destructive to use and what kills totally innocent bystanders. Both are physically addictive and cause far more misery and expense.
