It won’t take long before “Free” means taxpayer subsidized. As it is, their paying customers will pick up the tab to begin with and then it will be shuffled off to the taxpayers.
Marijuana will follow the same path as contraceptives and abortions. What first was the freedom just to use will be then further twisted to say someone, whether taxpayer or business, has to provide it at no/low cost to the users.
I will bet you $100 at some level, it already is subsidized. Who runs the "dispensaries?" who owns the buildings? Who is organizing the "poor" to get free weed there? Look and you will see it is likely some activist group with grants from somewhere - and free money means its from the government.
No, "free" already means taxpayer subsidized. Whether those taxpayers are the potheads who pay increased prices to make up the difference, or Berkeley finds a way to tax its residents to pay for the 2% mandate, either way -- taxpayers are already paying. (Well, assuming the potheads are taxpayers I suppose.....)
