Legalization of Marijuana?

Hi Humans,
You humans often allow politics and social feelings to decide real issues rather than practicalities. An example is the issue of marijuana and other "recreational" drugs. "Conservatives" tend to be opposed to any changes in the present system of regarding marijuana possession criminal. Other humans who consider themselves "progressive" favor legalization of marijuana in all cases and suggest that marijuana is not harmful. Trying to be objective, a perusal of PubMed will show articles that say marijuana can be harmful to the nervous system. The governor of California has pretty much said the same thing in opposition to legalizing marijuana. On the other hand, the present situation of criminalizing drugs has given criminals an opportunity to enter a business where honest merchants are barred, leaving the field open to the criminals.
So, this is what this dog recommends for you humans. Make marijuana and other drugs, tobacco, and firearms available to humans in a very restricted highly taxed way. They should be forbidden to children (including teenagers). Possession and use must be registered with the government. Misuse by anyone (especially children and teenagers) makes the registered owner liable for whatever harm is caused by them. Tax money received is to be all used to cure people of their addictions and to fight drug and gun cartels (none may be diverted for other purposes no matter how needed). In other words, partial legalization should not be construed as approval of drugs, tobacco, and firearms, but rather as a tool to counteract them.
