ATF regulates tobacco products. To the extent marijuana is regulated on the federal level, it's regulated by the DEA or (at the border) US Customs. Otherwise each state has regulatory entities and commissions which regulate marijuana.You misunderstood my post. Marijuana is not tobacco. I was just stating that there are special import conditions for different products and that those products being legal in 2 different countries doesn't imply you can bring it with you through a boarder. I was responding to @Doc Holliday that posted: "Whenever i’d cross the border i’d always be asked if i had any tobacco or alcohol products. I did not but i figured if i did & said so they likely would have got confiscated."
