if the bill passes. Canada’s recreational marijuana bill has three major problems The key word in the previous sentence is “if.” Right now, Canada is debating Trudeau’s bill, and there are three components to the opposition that could halt or delay its progress . To begin with, conservatives in Canada’s Parliament are concerned about the home-grow option in the current bill. While it would only make sense for a recreational legalization bill to allow households to grow their own cannabis, conservatives contend that it would give minors easier access to weed. Adolescent access to pot has long been a sticking point when trying to legalize adult-use marijuana throughout Canada and the U.S. Secondly, conservatives are also concerned about drivers being impaired behind the wheel. With alcohol, there’s a very cut-and-dried method of determining if a person is impaired: a breathalyzer test, along with a field sobriety test. There’s a well-defined barrier of 0.08% blood-alcohol content that draws a line in the sand for law enforcement in the U.S. between legal and illegal. There are no guidelines when it comes to testing for tetrahydrocannabinol (THC), the psychoactive component of cannabis. THC stays in the body for days or weeks, potentially leading to positive readings well after a person has used a cannabis product.
