In the following video, Motley Fool analyst Charly Travers takes a question from a Fool reader, who asks, "Now that marijuana is starting to become legalized with some of the states, I believe that eventually the federal government will legalize marijuana also. If it becomes federally legalized, then I believe the tobacco companies like Altria, Philip Morris (NYSE:PM) and Reynolds American (NYSE:RAI), and so on will start to get into this also because they already have the infrastructure and capital to produce and distribute tobacco. So my question is would it be a good idea to begin speculatively investing in American tobacco companies soon so to capitalize on the potential of the marijuana industry later?"
