I wanted to ask a question: In light of Colorado now legally allowing recreational marijuana use, I wanted to know what the moral implications of partaking in this or other “legal drugs” is from the Catholic prospective. Obviously the Church doesn’t have a problem with moderate alcohol use (provided a user does not drink themselves to such a point that they no longer possess use of their reason and do not engage in any dangerous or disordered activity while under the influence, like driving), but my understanding had been that using MJ or other illegal substances was sinful because to do so needlessly breaks the law. So can Catholics in Colorado now light up without incurring any legal or moral guilt? What about the fact that MJ is legal in the state but still illegal under American federal law?
***Disclaimer: I do not live in Colorado or Washington, and am not condoning or recommending the use of any substance to "get high"or advocating violating any federal or state laws. This is just a theoretical question about moral theology with real religious implications for Catholics in the United States.
