Proponents of legalization say marijuana is not addictive, yet peer-reviewed research concludes that it is. Proponents also say that most people who use marijuana will not move on to harder drugs, yet other studies note that most people who are addicted to other drugs started with alcohol and marijuana.

Advocates of legalization rightly point to the racial disparity of our jail and prison populations, noting that marijuana infractions often lead to lives trapped in the criminal justice system. We recognize the truth of that premise, while observing that recent sentencing reforms should soon reverse that trend, since possession of less than 10 grams of marijuana now results in a ticket of up to $200 and no jail time….

As lawmakers consider this issue, it is important to remember they are not only debating legalization of marijuana, but also commercialization of a drug into an industry the state will profit from. In seeking the common good, the state should protect its citizens.

We ask lawmakers to say “no” to legalization of marijuana, as Pope Francis explained in 2014 when speaking about marijuana and other recreational drugs: “… To say this ‘no,’ one has to say ‘yes’ to life, ‘yes’ to love, ‘yes’ to others, ‘yes’ to education, ‘yes’ to greater job opportunities. If we say ‘yes’ to all these things, there will be no room for illicit drugs, for alcohol abuse, for other forms of addiction.”
