Sen. Heather Steans and Rep. Kelly Cassidy, both of whom like Fritchey live on the city’s North Side, introduced legislation in March to allow the possession of up to 28 grams of pot, or about an ounce, and to grow five plants. Their proposals call for a tax of $50 an ounce, plus the standard state 6.25 percent sales tax. Local governments like the city and county collect their own sales taxes, so they likely also would bring in more money as a result of legalization.
